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.
Conventional, OVF autofocus Dual Pixel, live view autofocus Manual focus

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

EF 85mm f/1.8 USM, shot at F1.8
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

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

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.

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)

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.

DP review mentions the 360º rotation of the mode dial but don't say if the lock is as per the 60d. ie if it HAS to be unlocked or if it can be set to lock or not - ie do we have a choice?
Also the rear multi-controller - is it better or worse than the 60D (which was not very good).
One of the main turnoffs of the 60D was the loud and cheap shutter sound. It is probably the same mechanism as the 50D but I think the light plastic body made it sound worse.
I actually reverted to the 50D as I preferred the handling.
This 70D looks to have better shadow noise and hi ISO, better af and better movie af but will it still have the traits of the 60D that I didn't like eg unpleasant shutter sound and clumsy rear multi-controller and awkward Mode dial.
Also I see it has the ISO button in the middle (as per 60D) not the end where it is easy to find (as per 50D).

By Richt2000 (4 months ago)

Looks like Canon finally have progressed technology futher than just tweaking AF and raising mp and noise handling.

Interesting that you can select AF point and fire the shutter using the screen in live view mode. Much like mirrorless cameras have been doing for a few years now.

As an ex-wedding photographer, changing the AF point with the joystick whilst looking through the optical viewfinder was pretty quick and something I got used to. However shooting by 'touching people's eyes' on a touch screen is sooo much quicker.

I would guess that DSLRs will either go all EVF or dual Optical/EVF in the next few years. As the evf resolution improves, and jello effect illiminated, there is little advantage of the optical viewfinder.

Bring back canon's eye tracking af point selection 21st centuary I say!

The 50D is technically quite outdated, its not only the lack of video but noise performance isn't top of the notch. That said, the 50D is a tough, reliable workhorse in a rugged body that still can produce very nice images. Sold mine to friends, and they are very happy with it.

One flaw of the iPhone for that kind of work is that it's too much of a wide angle -- and noise is likely to be a problem. The worse the light is, the noisier it gets.

I own the Canon 70D and did a lot of research before making the purchase in November. Here is what the researchers recommend: For still photography the Nikon D7100 is the camera of choice, for video the Canon EOS 70 D. The lens also have a lot to do with image quality as well, so bear that in mind. I would recommend you do some additional research on the two cameras.

By AlexPuddephatt (3 months ago)

Seriously, I'd suggest you go pick one up and handle it. That'll probably make the difference in your buying choice.

I've got a 7D, and from what I've seen of the 70D reviews there's nothing that makes me think its any benefit for stills, particularly in low-light. If you're wanting video the 70D might be better processing (maybe).

Be really cautious over the online reviews comparing Canon / Nikon on this - from my choice a few months back I'd jsut suggest you're better renting or borrowing one - even if only for 10 minutes. Some of the personal use differences are that obvious but really difficult to describe

DVD format was still debated, blu-ray vs HD - turns out DVDs have a hard time competing with Streaming. My early adopter friend spent $11,000 on a large screen plasma before the HDMI standard. And many said network obsession with high def was crazy because no market had been demonstrated. Whether there's a mass market for 4K might be argued, but broadcasters and other content providers buy equipment on replacement cycles and 4K was high on the industry list at NAB shows with a lot of gear aimed at that segment, from production, sending, transmission, editing to receive end. I wouldn't try to call a cycle on it, but 4k would be is immense use in a significant number of areas outside consumer demand. It's coming quicker to affluent consumers that we believe. Some cinema cameras, Red, Black Magic, already there for quite a while.

Get yourself a new PC first, 4K video will be a pain in the ass to render at just a consumer level computer. To do this at a accepteble speed you'll need a PC dubbel the price of this camera, at least.

Most tv is not even broadcast at full hd. Let alone 4K.
I don't even think its possible to buy a 4k movie yet.

Hoping for some advice. I have 1000D and have used it for the last 5 years with limited issues - had to have the shutter replaced as it stripped. I shoot school sports predominantly, so it gets a great workout in the busy season. But also shoot portraits/groups, landscapes, travel and starting to doing more dance/wedding photography. Have 18-55, 18-250 HSM & 70-300 lens, but the 18-250 is what I use mostly.
While I love my 1000D, I feel limited especially with the portraits and groups in low light, I realise a F2.8 lens would be a great option, would an upgrade to 70D be as good an option based on the versatility of what I shoot?

I got the Canon 70D. It's a great camera and it do a great job on low light situations. For sports, the 7fps are really good. If you shoots JPGs, you can take a lot of shoots before get stuck with the buffer. I recommend to you to take that f2.8 lens. For people shoots, I recommend the Sigma 17-70 f2.8 lens. Greetings

The 2.8 lens will help in low light situations, but you don't want to shoot 2.8 for a group shot. You do need a 2.8 for sports, and make sure the camera has good af tracking such as 7d or the 1d for sports. I'm not sure how the 70d does on af tracking. You can pick up a used 7d for around $800 (US) on ebay, but the high iso is not that good compare to the new bodies. Good luck.

buy a fast lens!

lenes hold there value much better than the bodies do. get a 50mm 1.8 or a 30mm 1.4 sigma.

much cheaper than a new body.

I hesitate between the canon 70D or the panasonic GX7 camera.
I like how look like the GX7 but my main criteria is the photo quality and the park lenses.
What advice would you give me and why ?


By 12345ccr (4 months ago)

You should never buy a camera based on looks. Plus, by my experience, DSLR is generally better.

so far I've used my 400 DO and my 70-200 F2.8 ii - and they are bang on. I got this body for long lenses and as a compliment my 5D M3. which is for shorter focal lengths.

I tried 6 lenses and 2 bodies and they all front focused. I loved the camera otherwise, but had to return it because I need the focus to work when not in live view. (This is the eyepiece focus system that seems to have an issue). In addition it seems the problem changed over temperature of the camera body.
Have others tested this with different lenses?
I offered Canon to find one that doesn't do this and I'd buy it... they did not take me up on that.

Could you be more clear about - (This is the eyepiece focus system that seems to have an issue)?

70Ds conventional tracking AF is pretty good, but the Dual AF goes well only with the live mode.

AF micro ajustment

i ve tested my lenses and found only the Ef 50 1,8 II having the need to adjust by value 10 in the lens by lens adjustment menue. And only for macro and portrait with 1,8~3,5 aperture used.

My others 15-85 usm, 10-22 usm and ef-s 55-200 haven't shown this sensitiv issue.

Hello other 70d owners, did anyone recognized lenses in his basket having the need of adjustment ? Only lenses above 2,8 ?

Anyway, compared to my 40d the 70d is incredible having more details. this gives preshure for better lenses ! Microadjustment seems to be linked to age of lenses as well, right! (the 50/1.8 is developed ages ago for approx 12mbit sensors and acording number of resolution lines) .

Canon should place a testcard for buyers into the package, so they can compare with others and more easy adjust AF. Phase detection delivers incredible sharp pictures.

Wifi Functions nowadays.

Canon 70D have a pretty Wifi function
6 features today within the firmware:
. Transfer images between cameras (?)
. Smartphone App Mode
. PC/MAC EOS Utility
. WLAN Print
. Internet Image Gateway (Web Service)
. DLNA (TV Mediacenter mode)

Looking for the amount of data and pictures we now can take and how risky it is to travel weeks or even months with such a pretty camera i am missing a WLAN Backup function very strongly !
If you would like to have a WLAN Backup function as well, hit LIKE. Maybe someone from Canon read this.

I have a WIFI DISK from transcent which i can access from PC or Ipad or Mac even on the go, having Akku inside. Mapping is easy by IP-adress.
Security is done by the wifi settings. It would be pretty to have the posibility to transfer all or folders to such a WIFI disk on the go during long trips.
Reminding never put all eggs into one basket the WIFI disk is in the car or in hotel safe.

About the Electronic Level in 70D.

I can't get the electronic level displayed in either the VF or the screen while shooting.

I refer to Page 65-66 of the full Manual. I've set Menu 1 to Show the level and Spanner 3 has INFO button display options all ticked.

If I open the screen and press Info, the full-size level shows on the screen, but not in VF. That might be helpful if the camera was on a tripod, but not otherwise.

If I engage Live View (and half-press shutter button), no level is shown, either in VF or on screen. There should be a small camera icon with lines each side to confirm the camera is level - presumably superimposed on subject image.

Is there a fault with my camera? What am I doing wrong? Thanks

By Dirk1966DE (5 months ago)

Menu/ShootingSettingI=Viewfinder level=Show
In Liveview , due to my seetings , i have to press INFO button 2 or 4 times. But if "Level" is choosen it reminds, even if you switch LV off and on. In menu SetupSettingIII=INFO button display options i choosed only "Display Shooting functions", and in Customisation Buttons via Q-button i have changed SET from OFF to MENU. (in this case the Green self custom menue is shown!). Hope this helps for new starters, I have the 70D since early september, upgrading from 40D.

Question about video auto-exposure... Coming from a T2i/550D, and it's been my experience that the T2i video AE works by increasing/ decreasing ISO. This is non-optimal situation for me as darker environments result in very noisy footage as it ramps up past 800 ISO. Can anybody confirm whether this is the AE scheme with 70d? Or whether it is configurable? I'd like to be able to define, say, shutter speed or aperture as the go-to AE effector.

Follow-up question: Any subjective comments on low-light performance of video in 70d vs. T2i? Specifically interested in quality at/ above ISO 800.

For Photos within CFn1-6 Safty Shift can be set to Disable/Shutterspeed+Aperture/IsoShift. But only in M mode of Video you control Shutter Speed. Remind that to short or too long shutter speed in video may not fit. As the camera needs to take some pictures within a second. Depending on your settings. Priority for you is Aperture in Video and in any mode you can shift by wheel the two parameters. But ISO shift needs to be done by camera. It would'nt create a stop motion movie with 3 pictures in a second. Look for lowlight video Samples in youtube.

I currently have Canon Rebel Xsi ( 450 D) and I am planning to upgrade. My main motivation for the upgrade is to have better low light photographs, essentially lower noise while using high ISO.

Question: How much better 70D compared to Rebel Xsi (450 D) ?

By igor_s (5 months ago)

You can check it yourself either on DxOMark (compare SNR 18% charts) or in the 70D review by DPR (compare the test shots at higher ISOs).

btw, folks
Canon Korea (2013 Nov) has a teaser EOS M
that has a mini-dSLR shape

it may have dual pixel AF like the 70D

most likely have a fixed touchscreen, but I prefer vari-angle swivel screen instead like 70D

here: shows enhanced pic, too

It seems Canon cameras are getting better and better.

EOS 50D - Magnesium body
EOS 60D - Aliminum body
EOS 70D - Plastic body

Am I missing something?

60D was plastic as well. Both 60D and 70D have metal chassis.

so stupid if you think that way,
I am using 1D mark IV for several years and like that new cameras are getting lighter,
what's the point of aluminium or magnesium body ?
you sell it after 2 or 3 years,
plastic body make it lighter and that's a good thing

This conclusion page is a great example of diplomacy: lots of secondary points, like handling etc., and nothing about pictures relative quality.
Should we read it "nothing to boast"?
Nikon 7100 in this reviews shows better picture at the same price level, then - what we buy cameras for?
