Being able to use my Canon lenses on the Sony A7R II is the only way I would buy in to this camera, that being said, how do they perform?




The answer is quite simple, they do, so far. Auto focus, aperture and shutter all report accurately that I have tested. The Canon EF 16-35 f/4 L IS performed very well on the A7R2 using the Metabones IV EF-E converter, there appears to be no loss of image quality, no apparent vignetting or loss of sharpness. The EF 24-70 f/2.8 L II also appears to perform the same way. This is just my initial look and I will be testing further soon.

On the other hand, the resolution is quit astounding at 7952 x 5304, that means at 240 DPI you can print natively at 33 x 22. The menus are not ideal and the color is not to my liking, my post processing will need to be revised. The ability to pull detail in shadow areas is nothing short of amazing.

Update:
After Testing wide angle shots in San Francisco, I am definitely seeing softness around the edges of both the 16-35 f/4L IS and the 24-70 f/2.8 L II when used with the Metabonse IV, I can only conclude that at wide fields there is an issue, the two lenses I tested, I have been shooting with for a long time and they are good lenses, period! so this is coming from the adapter or the sensor. Read This article and see about telecentricity

The softness issue along with the Sony files, which are difficult to work with, luminance and color are both very difficult to control and require a lot more work than Canon files, lifting shadows is great, but it leads to very flat images. I have decided to return this camera and wait for either Canon to produce one or perhaps get a Nikon D810.

The image size from the A7R2 is what I would really consider ideal, I would like to see this in the next Canon camera. Being able to print native images 33" wide or tall is very appealing to me.

I really wanted to love this camera, I even began to like the ergonomics, the function menu is quit nice, the inability to quickly change AF points was not an enjoyable experience and some buttons are far to easily pressed by accident. The view finder was quit nice along with the flip screen monitor.

I recommend if you buy this camera to use only native lenses from either Sony, Sony/Zeiss or the new Zeiss Batis primes.
