Summary: In many respects, the Canon EOS 70D is an amazing camera. The flurry of 7 fps, with infinite buffer (or almost) and continuous autofocus, it is a strength indisputable, especially when you consider that the scanned files are 20 megapixels. Also the quality of the image is certainly at the top with regard to the APS-C, but to really differentiate the EOS 70D from all its peers is the performance of autofocus in Live View, for the first time really usable with satisfaction...
Pros: Excellent image quality, Excellent AF (also in Live View), 7 fps burst, Swivel touch screen, Good video mode.
Cons: Placement of some keys improved, One SD slot, No AF-assist lamp.
Summary: Conclusion The introduction of the Canon 70D doesn't mark a dramatic upturn in still image capture performance over its predecessor, the 60D. Probably the most significant changes in this regard are the inclusion of a 7 fps continuous shooting rate and the touchscreen functionality of the monitor.
Excerpt: The Canon 70D may very well have started a revolution with an innovative autofocus system that's new not only for Canon DSLRs, but also for the camera industry as a whole. Thanks to its Dual Pixel CMOS AF system, the Canon 70D -- a replacement for the three-year-old 60D -- could change the way you shoot both video and still images.
Excerpt: If I had to pick a do-everything-well APS-C format camera that does not cost a fortune, the Canon EOS 70D would be my recommendation. This camera has it all - great image quality with high resolution, a great AF system, a moderately large viewfinder, a fast/responsive shutter release combined with a very nice frame rate, a great LCD and compatibility with an incredible range of lenses, flashes and other accessories.
Excerpt: The Canon EOS 70D is the company's latest enthusiast-oriented SLR. It replaces the Canon 60D , and has various enhancements that distinguish it from the likes of the Canon EOS 700D . The viewfinder is significantly larger, there are lots of single-function buttons, a passive LCD screen on the top plate and a command dial and rear wheel for direct access to exposure settings.
Summary: It seems that there used to be a wealth of high-end enthusiast DSLRs to choose from, but with a longer wait between updates it appears that choice is gradually being reduced. Whether or not the EOS 70D should be your next Canon DSLR depends on your existing camera. Based on image quality alone, it may not warrant an upgrade from the EOS 60D, or even the EOS 50D.
Summary: The DSLR is on its last legs. Its entry-level models have been battered by relentless hordes of compact system cameras while its pro bodies now face an assault from Olympus’ superb OMD-EM1 and Sony’s new full-frame A7 and A7r . So where does that leave its mid-range cameras? Fighting for survival in the face of certain defeat, presumably.
Pros: Excellent new autofocus system, Superb image quality, Handy Wi-Fi and touchscreen
Conclusion: The latest EOS from Canon has been a few years in the making, but we're sure Canon users will agree it's been worth the wait. This model incorporates lots of contemporary technology such as Wi-Fi and touchscreen operation, as well as unveiling brand-new features like the Dual Pixel sensor, which provides even faster AF during Live View/video capture. Quite frankly, this camera raises the bar for the more serious enthusiast, and will take some beating.
Excerpt: The Canon EOS 70D is the latest Digital SLR from Canon, and one of the most advanced with an all-new 20.2 megapixel APS-C sensor, with dual pixel AF focus built into the sensor.
