Technology explained

The EOS 70D's headline feature is undoubtedly its unique 'Dual Pixel CMOS AF' sensor. This offers 20.2MP resolution, but uses two photodiodes for every single pixel ('facing' left and right), so that they're all capable of on-chip phase detection. This in turn promises hugely improved autofocus in both live view and movie recording. For example Canon says the EOS 70D will be able to hold a face in focus when the subject is moving back and forwards relative to the camera, even when filming with a fast prime lens at large apertures.

To understand what this technology is, and why it's a big deal, it's perhaps best to start with looking at how phase detection autofocus works, and some of the limitations of existing systems.

How phase detection autofocus works

Put simply, phase detection autofocus works by looking at the images projected by the left and right sides of the lens separately. When the subject is out of focus, these are 'out of phase' and don't coincide on the sensor, giving a blurred image. When the lens is moved into correct focus the images coincide, giving a sharp photograph. The key point is that it's possible to determine from a single measurement precisely how to move the lens to achieve correct focus.

Back Focus
In Focus
Front Focus
In this simplified schematic, you can see what happens to the image cast by the light passing through the left (blue dotted line) and right (red dotted lines) sides of the lens.

When in focus, the light from both sides of the lens converges to create a focused image. However, when not in focus, the images projected by two sides of the lens do not overlap (they are out of phase with one another).

Of course this is a massively simplified diagram with a single, vertical straight line as the subject (and no inversion of the image as it passes through the lens). The point is that we can derive information about focus if we can separately view light coming from opposite sides of the lens.

How does a phase detection sensor 'see'?

And we don't need the whole image to do this. Think about a strip of pixels taken from the sensor in the previous diagram. If you could make one such strip that receives light only from the left hand side of the lens and another that 'looks' only to the right-hand side of the lens, then you have enough information to find focus.

By comparing images from just these two strips it's possible to work out not only how far but also in which direction the lens needs to be moved to bring them into phase.
Back Focus
In Focus
Front Focus

This basic approach has been used by SLRs since autofocus first appeared in the mid-1980s. Some light is allowed to pass through the main mirror and redirected down to an autofocus sensor in the base of camera. This works when shooting with the optical viewfinder, but the moment the camera is switched to live view and the mirror flips up, the autofocus sensor no longer receives any light and so can't be used. One solution to this is Sony's 'SLT' design, which uses a fixed mirror that always feeds some light to the AF sensor. But these cameras can no longer use optical viewfinders, and have to use electronic ones instead - the isn't a bad thing per se, but not all photographers like them.

An alternative solution that's used by many current cameras (including Canon's recent entry-level SLRs, and many mirrorless cameras) is on-chip phase detection. Some of the pixels on the main image sensor are masked black on one half, so that they only register light coming from one side of the lens. By using left- and right-facing pixels, it's possible to implement phase detection focusing using the image sensor itself.

This diagram shows how on-chip phase detection was implemented on the first cameras to use it, the Fujifilm F300 EXR and Z800 EXR. Click here to read more about their PDAF system.

The problem with on-chip phase detection is that these pixels only register half the usual amount of light. So when it comes to taking the photograph they output a lower-quality noisier signal, and can't always be used for imaging, especially in low light; instead their values have to be interpolated from the surrounding pixels. This in turn means there can't be too many of them on the sensor, or image quality will drop noticeably. And as light levels drop, the signal quality from the masked pixels can deteriorate to the point that the focusing system doesn't work either. Canon's fix for all of these problems is, rather than masking the pixels, to split them into two.

Canon's new 'Dual Pixel CMOS AF' sensor

Canon's schematic of its Dual Pixel CMOS AF sensor structure. The top layer illustrates the light-gathering microlenses and conventional Bayer-type colour filter array. The lower layer shows how each pixel is split into two photodiodes, left and right, which are coloured blue and red respectively. (Note that this does not indicate different colour sensitivity.)

Canon's 'Dual Pixel CMOS AF' sensor looks at the concept of on-chip phase detection, and takes it to a logical conclusion. Instead of masking some pixels so they only 'face' left or right, it uses two photodiodes for each pixel, so every single one has a left- and right-facing component that can be used for phase detection. When a photograph is taken, the output from the two photodiodes is combined. The diagram below illustrates what this means for phase detection AF.

Lens back-focused
Overall view
Lens back-focused
Left-facing photosites
Lens back-focused
Right-facing photosites
Lens in focus
Overall view
Lens in focus
Left-facing photosites

Right-facing photosites

This immediately brings many theoretical advantages. In principle there's no significant light loss overall, so the quality of the output pixels shouldn't be lower compared to a conventional sensor. But because there are many more pixels capable of phase detection on the sensor, they can be used together for more accurate focusing, and in principle the system should work much better in low light.

Because the phase detection sites are more closely-spaced, the system can also work at small apertures, which allows continuous focusing in movie mode with the lens stopped down, or functional autofocus when using long lenses with teleconverters. Last but not least, because the main image sensor is used for focusing, it should be effectively immune from any systematic front- or back-focus problems that can come from an AF sensor with a separate light path.

According the Canon the EOS 70D's Dual Pixel CMOS AF system has the following key characteristics:

  • Usable phase detection AF area covers 80% of the frame horizontally and vertically
  • AF works at apertures down to F11
  • AF works in light levels as low as 0 EV
  • Can work with face detection to keep moving subjects in focus
Canon says the EOS 70D's 'Dual Pixel Hybrid AF' is active across 80% or the frame by width and height, as outlined here. (Pixels towards the edge aren't used for AF for technical reasons, despite having the same dual-photodiode structure.)

This means that almost wherever your subject is in the frame, the camera can attempt to track focus on it during live view and movie shooting using its on-sensor phase detection.

Lens compatibility

Canon has made no fewer than 156 EF lens models in the 26 years since the EOS system first appeared, and it says that 103 of them fully support Dual Pixel CMOS AF, including all current lenses. This means that these lenses only ever use phase detection for live view and movie focusing - there's no need for a slower contrast detection step. The other 53 lenses count as partially supported, which means that for One-Shot AF (either stills or movie) they use a hybrid system with phase detection to determine the initial focus movement, and contrast detection to fine-tune correct focus. So these lenses won't focus as fast and decisively in Live View.

It's really important to understand that this compatibility list relates only to live view and movie mode autofocus - it doesn't mean that other lenses won't work at all. Third party lenses from the likes of Sigma, Tamron and Tokina are fully expected to work absolutely fine on the EOS 70D - Canon hasn't listed them simply because it has no interest in determining how well other manufacturers' lenses work with its new AF system. So if you own some nice third party lenses, there's no need to worry that they might not work on the 70D.

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.

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

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.

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.
And as for most cameras, takin' it in your hands is way better to choose than read all reviews.

@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.

Coudy. So why are you so concerned about wifi on you DSLR. If you want to send them to someone just take the pics with your phone. 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.

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.

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!

One can't go wrong either way and it boils down to the lenses you've invested in. Happy snapping!

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...

You may want to put the Canon 6D in the comparison table and compare it to the Nikon D800. The results don't lie, the 6D beats the D800 from ISO 400 onwards.

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.

I think you're being quite charitable when you talk about the DOF preview button (i.e. you're not huge fans). I have a 6D which has the same position and it is woeful ergonomics. it's not "too bad" in the landscape orientation but disastrous in the portrait orientation.
