Sigma 24-105 f4 w/MC-11 on Sony a7R

[Michael Batten]

Afternoon everyone.

Has anyone used the above on a Sony a7R?

Looking for a cheaper alternative to the native 24-105 f4 which is £1,200 and the above is less than £800.

Thanks

Michael.

Interesting, I managed to find this website https://contrastly.com/in-depth-review-of-sigmas-mc-11-converter/ which suggests that with the a7R the AF is good and accurate.

From the video it looks ok. How it acquires focus on something that isn’t static may well differ. Depends what you shoot I guess.

It'll be a portrait lens and they tend to be quite static, only one way to tell and that would be at the camera shop.
