Trend Search - Product Review. During the early days of digital SLRs, Canon was pretty much the undisputed leader in CMOS image sensor technology. Almost every new EOS model came with an increase in resolution and high ISO range, and when the EOS 7D appeared in late 2009, the company had progressed from 3MP to 18MP, and ISO 1600 to ISO 12800, in just over nine years. But since then Canon's APS-C cameras have all sported variants on the same basic sensor design, to the extent that you could be forgiven for wondering what on earth their engineers were doing all day. Now we know.
The EOS 70D is a mid-range SLR for enthusiast photographers that from the outside looks like a sensible, indeed desirable upgrade to the EOS 60D. It borrows many of the best bits from Canon's existing SLRs, including the autofocus sensor from the EOS 7D, the fully articulated touchscreen from the EOS 700D (Rebel T5i), and built-in Wi-Fi from the EOS 6D. But on the inside it sports an entirely new sensor that is, potentially, revolutionary. It offers 20.2MP resolution, but uses a 'Dual Pixel CMOS AF' design in which every single pixel is split into two separately-readable photodiodes, facing left and right. This means that in principle they are all capable of phase detection autofocus in live view and movie mode.
In terms of control layout the EOS 70D is a logical evolution of the EOS 60D, adopting many of Canon's intervening updates and improvements. So it offers a full set of external controls to operate most key functions, and Canon's well-designed Quick Control screen to cover pretty much everything else. It also adopts the superb touchscreen interface that debuted on the EOS 650D (Rebel T4i), which we've found to be more useful than you might at first think. The 70D also regains an array of features that disappeared between the EOS 50D and 60D, such as AF microadjustment.

Canon's approach of splitting every single pixel on the sensor into two separately readable photosites promises, in theory at least, to overcome the biggest problems that have afflicted on-chip phase detection systems to date. We're certainly excited by what it claims to offer in principle - the ability to work across a large area of the frame, at apertures down to F11, and in low light is a pretty compelling combination. Throw in such goodies as face detection and tracking, and focus point selection by touch, and on paper the EOS 70D looks like it could offer the best live view autofocus of any camera on the market, bar none.
It's become increasingly rare for any manufacturer to show us technology that's genuinely innovative and unique, but that's exactly what Canon has done with the EOS 70D and its 'Dual Pixel CMOS AF' sensor. It's fair to say that on-sensor phase detection AF has so far shown lots of promise without necessarily being truly transformative to the shooting experience of most the cameras that use it, with Nikon's 1 System cameras being the most obvious exception. But while these offer exceptional focusing performance in good light, especially with regards to tracking moving subjects, the AF system can struggle the moment you try shooting indoors with a zoom lens.
