I got the Metabones IV adapter so I could use my Canon TSE lens on my A7R. At the time I discovered that it would work with most of my Canon lenses but not the 300 F4.
I now have the A7M2 while waiting for the A7RII.
The other day I went onto the Metabones site and discovered that there was a firmware update. (V0.41) for the adapter. I downloaded it and updated the adapter. It was a straight forward procedure.
I got out the 300 and give it a try. It worked. I can change aperture and I can hear the IS working when the shutter is half pressed. AF is still snail slow but that's OK.
This morning I tried the 300 along with two Sigma TCs. They work as well. Aperture control passes through. IS functions.
The test was shot at 16000 ISO, Av shutter, handheld. I was supporting the lens with my elbow on my desk. The poster is about 20 feet away. Sharpening is turned off in Lightroom.
The full frame and 100% crop for the 600mm version is included for reference.
I set OSS to manual and input the effective lens focal length via the camera menu.
