Canon EOS 70D: Canon’s Newest DSLR Game Changer
November 7, 2013Posted by on
ShutterStoppers think this new Canon released in the summer has some important new features.
The 70D isn’t called the game changer without merit, and you’ll quickly discover why. Intelligently engineered as a more refined replacement to the successful Canon EOS 60D, the 70D has a few new tricks up its sleeves. It is made for enthusiastic photographers, and comes with a variety of improvements that will create a buzz. The legendary Canon EOS is all grown up…
Canon EOS 70D: Canon’s Newest DSLR Game ChangerThe 70D improves from the 60D in many ways, a major one being within the sensor. It comes with the newest Dual Pixel CMOS sensor which is capable of capturing 20.2 MP images. The technology behind the sensor allows for a faster focusing during both Live View and video mode. 70D also has 19 cross-type AF points which is similar to the one present in the more expensive 7D.

for a more in depth consideration of this latest mid range Canon DSLR DP Review adds this
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.
On-chip phase detection is nothing new – we first saw it in the Fujifilm F300EXR back in 2010. Since then it’s been adopted in one form or another by most manufacturers, with arguably its most successful implementation coming in Nikon’s 1 System mirrorless models. But because until now it’s used relatively few active pixels scattered sparsely across the sensor, it’s had practical limitations, often only covering a restricted area of the frame and struggling once the light drops below outdoor daylight levels. Canon says that its Dual Pixel AF system, in contrast, works across an area 80% of the frame width and height, in light levels as low as 0 EV, and at apertures down to F11. This means it could well be the most capable live view autofocus system we’ve yet seen on any type of camera.
We’ll look at the technology behind the EOS 70D’s live view AF in more detail later, but let’s not forget that it has to work as a conventional SLR too. To this end it uses the same 19-point AF sensor as the EOS 7D for viewfinder shooting, but with slightly simplified control options in firmware. It can rattle shots off at 7fps for up to 65 frames in JPEG or 16 in RAW, and its standard ISO range covers 100-12800, with ISO 25600 as an expanded option. Image processing is via the DIGIC 5+ processor first seen in the EOS 5D Mark III.
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.
