Dual Pixel AF vs. Conventional AF accuracy

We set up a few tests to compare conventional, dedicated phase-detect autofocus to sensor-based phase-detect, to better understand the new system's behavior.

In general, we would expect any on-sensor focus method to be more accurate than an SLR's conventional AF system, because it is measuring focus from the plane where the image will be captured. The conventional, dedicated AF sensor sits elsewhere in the camera, behind its own optics and a dual mirror assembly (each aspect of which will always be slightly mis-aligned), which means that it isn't directly measuring focus - it's taking a measurement as a proxy for focus.

However, with most lenses, we expect the difference in focus between the two systems to be quite small. When working with the relatively small apertures offered by kit zooms, the greater depth of field is likely to hide any slight imprecision. But with large aperture lenses, differences are likely to become more noticeable.

AF accuracy and consistency

Canon EF 85mm f/1.8 USM

The Canon EF 85mm f/1.8 USM is a relatively challenging lens to focus, especially with the aperture wide-open, due to its narrow depth of field and lens aberrations at maximum aperture. However its axial chromatic aberration (green and purple fringing in front of and behind the focus plane) has the advantage of making it easy to assess where the camera has focused.

The above target provides a good focus subject, and its angled sides reveal front and back focusing. Roll over the apertures listed below to see the 70D's performance at different apertures, and click the crops to see a full-size image.

F2.8
F4

As we'd expect, the Dual Pixel AF system outperforms the conventional autofocus system - it's more consistent, shot-to-shot and it's more accurate, in terms of where it focuses. Interestingly, it's not quite as accurate as manually focusing the camera by using both live view and the depth-of-field preview button to ensure you're focusing at the aperture you're using to take the photo.

Interestingly, when we subjected the EOS 60D to the same test, we got similar, but slightly different results. The conventional phase-detection AF produced almost identically soft images, but switching to live view autofocus yielded the same results as manual focus - putting its contrast-detect AF method ahead of the 70D's Dual Pixel AF in terms of accuracy. It's perhaps not a surprise that contrast-detect autofocus is more accurate than phase-detect, since it keeps moving the lens until optimal focus is achieved, but it's important to remember that it's quite a bit slower than the 70D's Dual Pixel AF.

Real-world Portrait

Conventional, OVF autofocus Dual Pixel, live view autofocus Magnified live view

Here you can see what those differences mean in a real-world shooting situation - informal portraiture with the 85mm f/1.8. Using the conventional, optical viewfinder focus we got pretty good, if not bitingly sharp results. The shot used here represents a fairly typical result but, for one of our five shots, the camera was able to get even better results. However, the Dual Pixel AF system consistently produced better results than the conventional system - the five shots we took are almost indistinguishable.

Autofocus consistency comparison - Canon 85mm f/1.8
Conventional, OVF AF - 100% crops
Dual Pixel, live view AF - 100% crop
Magnified live view AF - 100% crops

However, manually focusing or using live view autofocus with greatly magnified (10x) live view, we were able to get the very best results. And this, to a degree, highlights one of the limitations of the Dual Pixel AF system: its AF points are considerably larger than the conventional PDAF sensor's, meaning that it's not always possible to precisely position the focus point where you want it.

While we were able to use the 10x magnification in this shot to achieve more precise positioning, it's hardly the ideal method when shooting portraits. While zoomed in to focus, we didn't notice our subject had drifted around in the frame.

The Dual Pixel AF system offers a relatively large focus point. It can be moved with some subtlety around the central 80-or-so percent of the frame. Pressing the magnify button on the right-hand shoulder of the camera zooms in. Pressing three times takes you to the maximum 10x zoom, at which point half-pressing the shutter button uses this small square to fine focus.

Autofocus microadjust (for viewfinder phase-detect AF)

It's possible to get much better results from the conventional phase detect AF system by using Autofocus Microadjust. This option resides in the camera's custom function menu (C.Fn II 13), and allows you to bias the lens's focus position foward or backward compared to where the AF sensor thinks it should be. So if the lens is consistently focusing behind or in front of your subject, you can fix this.

OVF focus, no AF Microadjustment Dual Pixel AF, no AF Microadjustment
OVF focus, -10 AF Adjustment Dual Pixel AF, -10 AF Adjustment

Here you can see that with a microadjustment of -10, the 85mm f/1.8 can be made to focus much more accurately using conventional phase-detect AF. It's also important to understand that this setting doesn't affect the Dual Pixel AF focusing, so using microadjustment won't throw it out of alignment.

With 3rd-party lenses: Sigma 18-35mm F1.8 DC HSM

The Sigma 18-35mm F1.8 DC HSM is optically superb, but when we reviewed it, we found that most Canon bodies struggled to focus it correctly. Like the 85mm, it's a lens whose wide aperture can really show off any inaccuracy in focus.

Sigma 18-35mm F1.8 DC HSM, shot at 35mm with a focus distance of around 4.5m
Conventional, OVF autofocus Dual Pixel, live view autofocus
F1.8
F2.5
F4

Here we see the same pattern as we saw with the Canon 85mm, with the on-sensor, Dual Pixel AF system doing a much better job of focusing the Sigma 18-35mm F1.8 lens. As you can see, switching to the the Dual Pixel AF system produces greater accuracy than the conventional AF system; we found the consistency to be improved, too.

This particular copy of the Sigma 18-35 F1.8 focused very well up close on our EOS 70D, but from about 3m to infinity, the camera just couldn't do better than you see above. However, Dual Pixel AF made this very sharp lens perform as well as we'd expect at all distances.

Kit Lens

EF-S 18-135mm f/3.5-5.6 IS STM zoom, shot at 135mm and around 10m
Conventional, OVF autofocus Dual Pixel, live view autofocus
F5.6
F7.1

The other factor to bear in mind is that real-world shooting doesn't always involve shooting high-contrast targets with fast telephoto lenses. With the EF-S 18-135mm f/3.5-5.6 IS STM kit zoom, any difference in accuracy between the conventional focus system and the Dual Pixel AF system disappears. Part of this could be down to the new STM design, but its smaller maximum aperture also means you're unlikely to see a big difference in a lot of shooting situations. These tests were performed at several focal lengths and distances, and the above results are representative of what we saw from each combination.

Limitations of Dual Pixel AF - tracking and continuous shooting

These tests are all very impressive, but Dual Pixel AF does have its problems, most notably to do with tracking a moving subject during continuous shooting. The 70D offers a 'Face Detect + Tracking' mode, in which it can follow your subject's face as they move around the frame, and keep them in focus. But if you combine this with continuous shooting - both high and low speed - the camera locks focus at the first frame, and doesn't attempt to refocus for successive shots. Worse still, the screen blacks out completely during continuous shooting, making the whole thing something of a guessing game, particularly when panning to follow a moving subject. This means that Dual Pixel AF is effectively limited to being a 'one shot' mode when shooting stills.

This behaviour is disappointingly reminiscent of first generation mirrorless cameras, which worked in much the same way. It looks very dated compared to the most recent models, which offer continuous shooting modes that show live view between frames, and can refocus between shots. This requires them to shoot at a reduced rate compared to their fastest possible, but the Olympus OM-D E-M1's 6.5fps with focus tracking isn't exactly sluggish. Hopefully Canon will develop and improve future generations of Dual Pixel AF in much the same way.

Overall assessment of Dual Pixel AF

Overall, our impressions of the Dual Pixel AF system are pretty positive - it's one of the fastest live view focus systems in a current DSLR, so there's not such a dramatic shift in behavior when you switch to live view shooting as with most DSLRs. We've also found that it offers clearly greater accuracy and consistency than the conventional AF system. It's worth noting that while you can use AF adjust to fine-tune the behavior of the conventional AF (and may well need this to get usable results), the setting has no effect on the live view autofocus.

It's also worth noting that the Dual Pixel AF system doesn't necessarily use the same aperture as will be used to take a photo - instead it will use the diaphragm to control the amount of light reaching the sensor. In our tests, we found that this could result in a very small drop in consistency, if you're shooting images with a wide aperture in bright light, because that's where you'll have the largest discrepancy between the camera's working aperture value and your chosen shooting aperture.

Overall, any inaccuracy we have found with Dual Pixel AF has been very small. Anyone sticking with the kit lens will likely never encounter the difference we found between conventional phase-detect and Dual Pixel autofocus, but those with larger lens collections or who plan to purchase faster zooms and primes will benefit from shooting in live view mode with the 70D. Far from being 'just for video,' Canon's Dual Pixel autofocus does seem to offer a good balance between speed and accuracy, making it a good go-to mode when sharpness is critical, espeically when shooting at large apertures.

Overall, our testing makes it appear the 70D's Dual Pixel AF gives most of the speed advantage of conventional phase detection AF and most of the accuracy benefits of contrast detection, but doesn't quite manage to offer all of both.

Tracking AF

Sadly Dual Pixel AF is only really used for single image AF or movie shooting (see the movie page to see how it does). If you need continuous autofocus with tracking, you have to use the 70D's conventional AF system. We looked at how well it could track a subject walking towards the camera and left-to-right across the frame.

In wide-area AF, the Canon EOS 70D did reasonably well with both an older 85mm USM lens and the new 18-135mm STM lens (set to 85mm to match). There were more dropped frames with the USM lens (just one), but the LCD overlay points lit up and followed our subject as she walked toward the camera and tracked as well as we expected. Below we show only the 18-135mm results for the sake of brevity.

Wow, just finished watching the 70D vs the 7100. I did have the 7100 at one time and sold it. Guess I should have spent more time with it. However, a friend of mine is using his 70D for video and I like how the 70D has that pull out LCD touch monitor and can chose different focus points instantly where the 7100 you have to arrow your focus box to that location. End up getting the D800E because I shoot more photos but its still a Nikon and the video is the same setup. Image quality is great though but I like how the video is setup on the canon. Looks easier to work with. Should I just get the 70D or the new 7D to do video. I don't think the new 7D has a flip out Lcd touch screen which i think is really cool. Himm. But I shoot more photos than I do video. What do I do.

Well, it's kind of like buying a Toyota Camry or Honda Accord. They're comparable and either will get the job done. Both Nikon and Canon have have their followings. Look for features that you think you'll use: wireless, gps, video autofocus... (because image quality and lens selection are pretty much the same) Right now the most interesting lenses are being made by sigma, and the only camera body that stands out as being different is the sony a7.

Do you mean the forthcoming 70D, or the original one? Just as there are other cars besides Camrys and accords, there are other worthy camera brands and I think they are worth talking about. You don't specify what you want you want your camera for (landscapes? Sports? Children? Studio shots?) but there are other cameras that have garnered excellent response--the Fuji XT-1 or the Pentax K3, which is weather-sealed. You don't specify that you want full-frame … but if you're looking at the original 70D versus a Nikon D7100 I would go for the latter; if it's the *new* 70D, pending the official review, I'll go for that.

Upgraded from 350d and probably expecting too much of that ?
Because , after using it for a couple of months, I have more than one problem with this camera:
- some lenses I have give very poor results, the 28-135 f3.5-5.6 IS is the best example, sometimes I have to put the IS OFF to get a decent result
- red eyes all over when using the internal flash
- burst rate slows down after use of the camera for some time, so much that for about 15 seconds, taking another pîcture is impossible, awful when shooting a show
- in auto mode: flash sync jumps to 1/30 most of the time, there really was nothing wrong with the 1/60 on the 350d
- also in auto mode: focusing & metering was better in the 350d, I've started using that camera again for some things

I also found out that:
- the bulk lens 18-55 that came with the 350d performs well and shows the potential of the 70d
- tested the Canon 18-135 bulk lens of a friend, clearly better results than the 28-135 (price is about the same)

Just wanted to point out a couple things that you might not be considering. #1 your resolution more than doubled so you're going to see the imperfections in your lenses a lot more on the 70D. The 28-135mm is honestly a terrible lens. Pick a focal length that you like and buy a more specialized lens with a larger maximum aperture. For example the canon 50mm 1.8 costs around $100 and will blow your mind with image quality compared that terrible lens. #2 99.9% of the time when you're having write speed issues it's because of your memory cards. Look up the manufacturers max write speed for a card in MB/S. Then check your file sizes x frame rate and you'll have an idea how much data you need to write per second not to fill your buffer.

Hello lake4444, I'm not sure why "camera people" talk so much, say so little, fight so much and never answer a question. In any event, the 70D is an excellent mid-level DLSR camera. It is certainly not an entry level model and it certainly is not a professional model, so it sits nicely in the middle of the range. I beginner can take spectacular shots using it, there is a huge amount of learning you can do with this camera and anything less than a career in photography will see you never require another camera - it make take you quite awhile to learn everything it does, and many years beyond that to master the controls, but you can take excellent pictures right out of the box. This is Canon's premiere video DSLR and you won't find better video capabilities anywhere. Don't let all the talk about "models" and waiting for the "next" one throw you off - there is no end to the models. When I first entered into DSLR photography, I went to buy a Rebel Ti, found a 2Ti and 3Ti was out in 1 week

There are an awful lot of things that you probably need to think about. For example, if you plan on out door, all weather use, then a sealed camera is a very good idea. Canon added the dust and moisture seals back with the 70D. You don't want to dunk it a pond, or drag by the strap through a dune, but it won't die in a light rain or start making grinding noises when the shutter moves on a dusty day. DSLR results have more to do with the lens than the body, so one thing that you will discover is that what ever camera you chose, the lenses will tend to increasingly tie you to that brand. So, think carefully. What kind of photography do you want to do? What kind of money do you have/can you stand to spend on it? The 70D is an excellent camera body. So are most others.

Hello, just my two cents worth. I own a 5dMarkII but wanted a cheaper alternative for distance so I bought the 70d. I was waiting on the 7D replacement but there was a special deal of no tax (plus I had a trade in). Anyway, I bought the 70d.

Pros- I love the touch screen! The number of focus points over my 5DMarkII are wonderful.

Cons- I feel the noise at higher ISO is much more prevalent than in my MarKII.

I wish I had waiting on the 7D replacement. I must say I am a bit disappointed.

Andrehk,

Why would you say it is better?

1. You can buy ultra wide lenses to counter the crop factor with FF lenses like the 16-35 (The Tokina 11-16 is a great piece of glass for Crop cameras)

2. They are good for wildlife and sports photography because of the crop factor of the bodies.

3. They are the most manufactured cameras and most popular.

4. Image quality is not that far off compared to a FF.

5. They are more affordable.

I have owned crops and FF cameras and I struggle to find a major difference between the quality of the images when a good lens is attached and the photo is taken properly. I will say the high ISO noise of crops isn't as good as FF, but the difference isn't that noticeable in most situations.

So a little better maybe for some things such as High ISO performance, but a mile? I doubt that.

Hi Donnie. Yes he is. I ordered a new Canon 70D the first week of May, prior to seeing this video. Once I saw the video I was concerned and decided to run my own test using my 16-35 f2.8 canon lens. I mounted the camera on a tripod and took a picture using the center focus through the viewfinder and 1 using the LCD. The results were noticeably different. In truth my understanding is that in everyday use most folks would never have an issue. I did not want to deal with the issue and decided to spend more money and get a full frame 6D, which has had the price reduced. So I was glad to be notified of the issue. Also, I rarely shoot video so the 6D ultimately was a better choice for me. You can see the difference in the two pictures I took at

Well, this yes and no. He complains that microadjustment "should always work". In my experience, it varies a lot with focal distance.
And to focus on a thing on the same plane, well, that was the kind of scene were contrast detection would to better.
And honestly, I could not see a difference in most of the pictures.
but the best way to confirm: try it. As he said, it is not easy to reproduce, so will be hard to confirm, or meet on real life.
It's personal, but I wouldn't defer a purchase based on that video.

@sevoman
So far, the xxD line has consistently shown these advantages over the Rebel range (also known as the xxxD range):
- bigger build with better handling and weather sealing
- aluminium chassis, combined with plastic (a benefit often ignored because it's wrongly considered inferior to magnesium allow)
- expanded AF zones with more points being cross type
- faster burst rates for continuous shooting (70D = 7fps)
- top LCD control panel combined with greater number of external controls and switches
- and will usually sport features which the xxD range inherit from the xD range, in the case of the 70D it is built in WiFi as featured in the 6D.
In the case of the 70D, it offers all of the above vs the 700D and sports a new higher resolution sensor with improved AF performance in Live View and in Video.
You can also add in-camera aberration correction for 40 Canon lenses at a time (using EOS Utility) where the camera will correct for vignetting and colour fringing

How do you figure that the sensors on the 7D (18MP) and 70D (20MP) are the same for video? Especially since the 70D uses dual pixel technology, which is an inherent feature of the actual sensor?
That is why the 70D is so much better at AF in Live View and Video. As such, the image quality, if considered across the duration of a video clip, is better for the 70D because more of it is in focus...
The 7D would only be better all-round if it came down to handling, AF zones and ruggedness.

If you're already invested in Canon lenses, the 70D would be the logical choice from a 40D.
You should also look at the 700D, which is not as fast as the 70D on AF in live view or video, and which is more compact, but which delivers great stills and has it's own relatively good hybrid AF system for video. It also boasts articulated LCD with touchscreen.
If you dont have any Canon lenses other than the kit lens you got with your 40D, you could afford to look really wide and could even consider the Nikon D5300...

Faster than 7.5 fps in jpg...?
Only option is the 7D at 8 fps or you'll have to skip to 1Dx...
Similarly, this is as deep as it gets on burst shots in this category.
Unless you're referring to RAW, and even then you're out of options.
It may be that your AF experience is as a result of the glass you paired with the camera because the AF can not get any faster on my camera even if I wanted when I use any of my EF(L) lenses or even the kit lens (18-135 STM).
And that goes for the optical viewfinder as well as live view.
But, you have to trust your system and if it did not work for you, it's better to do what you did and change.
Happy snapping!

The picture quality will be about the same because the are compressed to be sent from you phone. Buying a camera with this option is a waste of money and the wifi rarely works well. Anytime you send something through wifi you lose data and therefore quality. Canon and nikon use the wifi thing as a sales gimic because they no longer build good cameras. Most amateurs don't understand this. Kind of like the megapixel thing. The human eye cannot tell the difference between 10 mp and 20 mp. Its a sales ploy. I use an older Nikon D90 ar 10 mp that will out perform any of the new cameras. Of course you need a good lense. Not one of the cheapies that come in a kit.

Dear RickC452: I find WiFi very useful for nature photography. I set up my Canon 6D camera on a tripod near a bird's nest. Retreat to a blind, watch the camera image on my iPad and activate the shuttle when the scene is right. I've got a few prizes for images taken in this way. As for the number of pixels, more pixels allows you to crop down while maintaining image quality. Also more pixels allows for larger prints. I find I can print larger sizes and get "image snap" that i couldn't get with my older 8 and 10 meg sensors. One wants to print images at 200 dpi if possible to maintain snap while viewing prints within a 3' to 5' range. a 20 megapixel sensor will allow prints up to 18" x 27" under these criteria.

Your opinion on this is factually incorrect.
The picture taken by the DSLR will have benefitted from zoom, image stabilisation, enhanced jpg processing, improved low light performance - things a cell phone camera cant do. And the picture is not as badly compressed as you make out when sent to a smartphone.
I think you are really missing the point.
Apparently you have a Pentax and a Nikon D90 which you consider adequate if not superior, really no need for you to troll the 70D page only to bash it.
The wifi option also gives you full remote control over the 70D so as to remotely adjust and actuate it - that's hardly a gimmick...

While Wi-Fi is not a necessity for everyone you act as if it is completely pointless. More and more pros (and amateurs too) are using the wi-fi features that cameras offer for quick uploads and remote shooting. Again it is not a feature everyone will need or use, but it is helpful. Just like having more megapixels. In most cases 10mp is adequate as but with 20mp (assuming the sensor is the same size) you have the ability to resolve more detail and crop photos a lot more while maintaining higher levels of detail. Again for most practical shooting this isn't really needed but for some shooters the extra MPs are worth it. Judging from your comments you don't seem to be one who embraces new technologies too often.

Wanted to sync GPS with my camera's time (for GEOSetter) and I had to take the SD card out in to the computer to read exif date digitized instead of just check time difference using smartphone and EOS app. dont understand why would wifi transfer remove all EXIF information from a photo!!

Sharing photos using smartphone and EOS remote app issues.
Can anyone help me find the solution for this? Here is the deal.
I am out in the woods with only mobile network available for internet access.
I am connected to my smartphone using wifi with my Canon 70D.
Now everything works as long as I don't try to send the image directly or indirectly using apps like whatsapp, skype, email right away.

Android phones have priority for wifi over mobile networks, while in most cases that is desirable, it is not in the case of sharing photos while wifi is on but isn't connected to internet AND mobile data connection is.
So you are stuck with downloading your photos to your smartphone, disconnecting from the camera and sending using mobile data connection once wifi isnt connected. Why the heck is there the option for sharing in EOS remote app? For other scenarios??

Did I miss some option how to have canon 70D wifi connected and still be on the internet using mobile data (SIM card)??

In essence, yes - you would have to download to your phone and then share.
The limitation of not being able to simultaneously run data on wifi and 3G/LTE (GSM), is a phone problem.
The Samsung S5 and Note3 can do so but not all Android devices can - a general rule of thumb is that phones with the ability to tether data from a GSM signal to a WiFi signal ('hotspot') should be able to run data side by side on GSM and WiFi.
I have no problem using my Note3 to share pictures directly from the EOS App on an internet based platform while being connected to the camera on WiFi.
PS, some Android devices will disconnect Mobile Data when you activate WiFi and you have to then manually switch Mobile Data back on while on WiFi - make sure your device is not doing this, especially if you are using certain Sony or LG devices.

RickC452 is right. Unless you are a photojournalist one seldom send photos taken by a DSLR so much in a hurry. Just use a smartphone for casual shots. I almost never send any DSLR quality photos by wifi. Photos taken by a DSLR should be treated more seriously. They may need more post-processing and later down sizing before they qualify to be sent out by wifi or shared by other means.

The characteristic of having more megapixels is more an advantage for those who need this resource. You should take into account the destination of the material beyond the digital medium. If a photographer clicks a scene destined to fill the space of the side of a building with an ad, it definitely has to be taken into account when shooting with more megapixels. Basic thing.

One more thing. The pentax has in camera stableization not in the lens like canon and Nikon. That's what makes it work so well with older lenses. Canon and Nikon don't want you using older lenses. They want you money.

non stabilized lenses can work nicely on Canon. A lens without IS is not useless. A non IS lens does not become invalid when a new IS lens in same range shows up.
In some applications IS actually have no use.

The only thing the Pentax doesn't have is an external mic port. But no body in their right mind does pro video work with a DSLR anyway. And you can get it a wild assortment of colors. Check it out, use one and you will also dump canon and Nikon like I did.

Your all missing out on the best camera out there in their in the mid price range. The Pentax K 50. Better than both the canon and the Nikon and cheaper. I switched because both canons and nikons are getting cheap in their builds. And the pentax can use any pentax lense ever made. I'm using a 135 mm f2.0 from the 80s with awsome results.

Awesome camera - the best mid sized DSLR available today and sorry, but better than the Nikon D7100.
They both take great pictures but the Canon is in another league when it comes to handling - the touchscreen, the wifi option using the EOS App on a smartphone... great!
The wifi was super simple to setup - the app allows remote trigger, exposure setting, ISO/aperture setting and focus area setting and screen mirroring (with camera in live view ). The creative options are endless!
I've shot about 500 pictures with a Sigma 50-150mm, f/2.8 EX APO DC HSM lens and the AF is pin sharp in stills whether you use the opt viewfinder, or live view or video. You can of course fine tune AF on the 70D if necessary but I didn't need to.
I love this camera, the balance between size, handling, features, performance and price point is great. Get it!

better than D7100? what are you smoking? plastique build, instead of a mag-alloy case like the D7100, one SD Card Slot, instead of 2 on the D7100. AA Filter - the D7100 doesn't have it, and last but least: check out DxOMark, the D70 is just another iteration with the same in terms of IQ...now with phase detection, but apart this, always the same IQ since virtually the EOS 550D.

LoL - I suppose we can go round and round - 70D has articulated LCD with touch screen (including touch directed focus point), 7 fps with greater buffer and the video functionality is overall of much greater performance.
Not true that 70D is plastic - it's aluminium chasis with dust and moisture seals.
I agree that dual card slots would have been nice but it's just that - nice. It's greatest use is perhaps dedicating the one to video and the other to stills, or RAW and JPEG - but that's not a big deal.
The Nikon has a slight edge in terms of stills and dynamic range, the Canon has the edge in terms of video and handling (did I mention the creative options provided by wifi such as remote trigger??)
Another thing that I dont like with the D7100 is the vertical battery grip - 1 battery goes in the camera and the other in the grip magazine which means you have to remove the grip to charge the battery in the camera. The Canon takes both in the magazine (which was also true for the Nikon D90, but for some reason they changed it). I suppose you could consider a 3rd party grip...
Horses for courses I guess!

DSLRs are system cameras. The "best" camera is from the system you are most familiar with and has invested the most lenses. Most professional sports or event photographers would swear by the Canon 1DX but if a newbie get his hand on one he would most likely be baffled. His first reaction would be why it is so heavy and "complicated".

It is HIGHLY unlikely that you would in fact have a problem with AF using the opt viewfinder with large aperature lenses - I used my camera along with 4 other 70D users on a Namibia/Botswana safari past the Caprivi and the results were great from all users - pin sharp results.
The review that you are referring to is questionable and Canon was unable to reproduce that single known example as stated by the reviewer. The camera is great and it is clear why it has canabalised 7D sales...

Bought a 70D after many rave reviews like this one and for wanting a faster auto focus than my Fuji X100.

With the 18-135 Kit lens indoor shooting without flash is very difficult.
70D very bad high ISO capability compared to X100.

Bought a Sigma 18-35 1.8 to cure the low light performance and discovered to my absolute dismay now that the view finder auto focus is not capturing the right object, thus rendering the 18-35 1.8 useless indoors with its short focal length.

I would have trashed the 70D for a Nikon immediately if not for the touch screen. I feel that is immoral that no you tube review of 70d or Sigma 18-35 mentions that the auto focus of the 70d is useless rendering the lens meaningless.

You are right.
It even fails to focus with the canon own lenses( 1.8 and 1.4 primes)
So basically this camera is mainly functional with the 18-135mm lens.
If you want to use a prime, then good luck.

The problem you are describing could be as a result of so many variable settings, it is highly unlikely that the camera itself is the cause - you should fix the focal point on the camera and then shoot to confirm that the lens delivers sharp pictures on this camera, which it will. You also have to consider the light meteting / evaluation setting - shooting indoors in low light with contrasting backdrops will almost definitely draw the AF to the background if you're shooting in evaluative metering as opposed to partial metering. Bottom line - I've not observed what you're describing even when I try to replicatd that problem...

This looks like a nice camera. Comparing this to a Nikon 7100, that 24MP is too high in MP, that 20MP gives a better balance in a APS-C sensor in noise to MP. The images look better at ISO 800 and above in 70D. That is over all.

I was handed a 70D to shoot videos at an art reception. The autofocus is nothing short of amazing! Almost no hunting at all, it hit the mark every time, and when somebody walked into the scene at a closer distance the focus pull was decisive and smooth. It's at least as good as most professional camcorders, especially in the way it arbitrates where to put the focus. And the video noise around iso 1600 is very unobstrusive.

This is the go-to DSLR for party videos. I'm not going to give up my D800, but I may pick up a 70D for people & events videos.
