I bought a Metabones to use Canon lenses on a new Sony A7iii. It stopped working on the third day. The camera doesn’t read aperture. The LED on the Metabones is unlit.
The Metabones contacts look like they are out of alignment with the camera flange, and a contact pin in the camera mount seems to be missing. If correct, then the Metabones not only failed, it damaged the camera.
The reviews at B&H photo report similar problems. I wish I had read these before ordering.
I like the Sony a lot, but am now thinking that an EOS R would be more reliable with Canon lenses.
Hopefully Henrys will be helpful with a replacement since I bought these together.
