The Canon EF35/2 IS works very well on the SONY ⍺7RII, SONY ⍺7RIII and SONY ⍺7III with the Sigma Mount Converter MC-11:
- Autofocus is fast and precise
- the image stabilization (IS) works flawlessly
- aperture setting can be done from the camera
- EXIF-data is transmitted correctly
The EF35/2 is extremely sharp, even wide open, and it renders a very pleasing bokeh. Its resolving power is adequate for the 42MP sensor of the SONY ⍺7RII or ONY ⍺7RIII. All in all this is a very good wide angle lens at a reasonable price.
