Autofocus not working (bmpcc4k)

Hello, I bought the Black Magic Pocket Cinema Camera 4k with a speedbooster Viltrox EF-M2 II. My lense is Canon 24-105L. When I set up my camera, neither the IS or autofocus worked. I fixed the IS problem with a downgrade of Viltrox to version 2.3. But the autofocus is still not working - button doesn’t do anything. Did any of you have a similar problem?

I have a sigma and with the same viltrox and it works occasionally. I heard that the metabones works great but its four times the cost.

You might try the forum search function with the keyword "Viltrox" - should give you a good overview of the issue.

I had the same Viltrox and it didn't work. I bought the much much better metabones adapter which is specially designed for the Pocket: https://www.metabones.com/products/details/MB_SPEF-m43-BTA
It works very good!
Viltrox just don't work.

It seems to work for some. Why so strict, even if you can afford a Metabones?

anyone found a solution for this (viltrox)?

Yes, don't buy it. Sorry to say but Metabones is much better.
