In contrast, Canon's Hybrid AF system, used by the T4i, T5i, SL1, and EOS M, simply supplements its phase-detection AF with contrast AF. DPA splits each photodiode in two, comparing the signals from each half using a phase-detection algorithm for autofocus, in addition to using the signal from the entire photodiode for image data. Typically, a single photodiode - the element on a sensor that collects light and converts it to an electrical signal that carries the image information - only passes on image data.

The new Dual Pixel CMOS AF (DPA) autofocus system is a definite update over many previous Canon models, both from a performance and features perspective.
(Using a 95MBps SanDisk Extreme Pro SD card.) JPEG runs past 30 shots at a rate of 7.1fps raw shooting slowed down to about 2.5fps after about 17 shots during testing, but in field testing I sustained reasonably fast 9-shot bursts of raw+JPEG with Servo AI focus. In Live View mode, that rises to 1.5 seconds.Ĭontinuous shooting operates really fast for this class, with a sufficiently deep buffer to make the speed useful. Two sequential JPEG or raw shots also run about 0.2 second, rising to only half a second with flash enabled. Time to focus, expose, and shoot in good light runs a zippy 0.2 second and in dim light a modest 0.8 second.
(Looking back at my preproduction report, I think I misstated that result as 0.3 second rather than 0.7 second.) It powers on, focuses, and shoots in about 0.4 second, not quite Nikon fast, but generally fast enough and better than many Canons.
With the exception of focusing speed in dim light, the 70D delivers excellent performance. Low-light video has nice tonality and a reasonable dynamic range, but there's still quite a bit of color noise. It looks a little better than the T5i, though not obviously, and most casual users probably won't see a big difference.

It displays edge artifacts - ringing, aliasing, moire, and crawling edges - which, as is common, get worse as ISO sensitivity rises. Thankfully, the video from the production unit looked better than the preproduction unit, though it suffers from the same general softness as stills, compounded by the relatively low resolution of HD. (note: these are in the Adobe RGB color space) I was occasionally able to produce sharper images at ISO 1600 by shooting raw, but not always. JPEG shots look OK up to about ISO 1600 beyond that it depends upon scene content. (The T5i looks better starting at ISO 1600, but that seems to be because the T5i meters a third of a stop brighter.) It's a bit better than the Rebel T5i across the entire sensitivity range, though you really have to scrutinize them.

Yes, it's still an advance over the 60D, but not enormously - I don't think you even gain a full stop of usability, and any advantages seem to stem from the slight increase in resolution. However, it's simply not as good as the Nikon D7100. Not outstanding for the money, but not bad, either. The image quality didn't change noticeably between my preproduction tests and my final tests, but my opinion has. However, pixel peepers will likely be disappointed with the still photo quality, which really should be better for the money. And with only a couple of exceptions, I like the 70D and enjoy shooting with it it's fast and fluid. It comes with a completely overhauled, Live View/video-optimized autofocus system that doesn't require special lenses a more streamlined body design with an articulated touch screen and Wi-Fi support. There's so much to like about the eagerly awaited replacement for the Canon EOS 60D, the 70D.
