Canon EOS 70D vs Sony SLT-A77 Comparison and AF Test

DxOMark has posted an article of the Canon EOS 70D vs Sony SLT-A77 comparison and auto-focus test. Canon EOS 70D has likely the most advanced solution called “Dual Pixel CMOS sensor”. On-sensor phase detect AF is available on every pixel and adopted for initial subject acquisition.

DxOMark tests the newly announced Canon EOS 70D auto-focus and compared it with the Sony SLT-A77 AF. Both cameras tested with different lenses. Canon 70D testes using the EF 40mm f/2.8 STM and the DT 16-50mm f/2.8 OSS SSM lens used for the Sony A77.

From the DxOMark conclusion:

The Canon EOS 70D is an attractive proposition for both stills photographers and video users. The new Dual Pixel CMOS AF cleverly solves the problem of the redundant viewfinder based phase detection AF system when recording video and neatly avoids the patented trans-missive mirror solution adopted by Sony.

As well as retaining an optical viewfinder, the Dual Pixel CMOS AF sensor with its total of 40 million pixels used for image capture shows a small but palpable increase in lowlight performance and higher levels of sharpness than previous APS-C cameras from the firm.

For video enthusiasts, this camera is one of the best choices available on the market currently and at least is a viable option to the entirely likeable and very capable Sony SLT models

The Canon EOS 70D DSLR is an APS-C camera with a brand-new 20.2MP “Dual Pixel CMOS AF” sensor and features 19-point AF module from the EOS 7D for viewfinder shooting, touch screen control via its fully articulated 3¨ LCD, and built-in Wi-Fi.
