I was always interested to know what is the resolution power limit of Canon EF24-70mm f/2.8 M2 combined with the high resolution body and how this compares to similar lense type from different vendors.
On Canon 1DX this is just perfect piece of glass.
Few days back I received Matabone III adaptor which gave me ability to mount Canon lenses on Sony a7R body.
With that I was finally able to test Canon EF24-70mm f/2.8 M2 on 36mpx Sony a7R body.
As result there is also comparison of image quality between Canon EF24-70mm f/2.8 M2 and Sony Zeiss 24-70 f/4 OSS.
There are two 100% crops at 24mm focal lens and two 100% crops at 70mm focal lens.
All shots are done hand held using camera autofocus.
Focus speed of Canon EF24-70mm f/2.8 M2 with Matabone III is very slow - few seconds of hunting and searching for focus peak.
Sony Zeiss 24-70 f/4 OSS focuses almost instantly.
RAW files from Sony a7R were process using Phase One Capture One with default settings, no adjustements at all
Test results demonstrate that Canon EF24-70mm f/2.8 M2 is much superior to Sony Zeiss 24-70 f/4 OSS in resolution and color reproduction and overall image quality . Especially this is noticable at 70mm focal length .
From test pictures it is obvious that even on 36mpx Sony a7R body Canon EF24-70mm f/2.8 M2 still does not reach it's limit in resolution power. This combination is perfect one when focus speed is not important.
On the other end Sony a7R with Sony Zeiss 24-70 f/4 OSS is a fairly good combination as general purpose walk-around point and shoot camera.
I also tested Canon TSE 17 on a7R and image quality , color rendering and resulution is also of top possible quality.
It seems that Canon TSE 17 the same as Canon EF24-70mm f/2.8 M2 still does not reach it's resolution power limit on a7R
Canon TSE 17 on Sony a7R looks as perfect combination for Architecture and Landscape photograpy.
