Hello all.

I've been using this setup for over a year, with no issues.

Recently, I started having some issues where the focus travels full range without grabbing focus after a few shots of starting to use the lens that day (sometimes as few as 5 or 6).

If I detach the lens and attach it again it might work for another few shots, or 20, I cannot find a pattern.

I just shot 100 test photos straight with no issues.

I tested with someone else's adapter, and I didn't got any issues. (I'm missing on testing on other camera with the my adapter).

I already "formatted" the lens on the dock.

There are also no firmware updates to neither the lens or the camera at the moment.

The issue doesn't happen with my Sigma 40/1.4 attached.

Anyone had any similar situation?

Thanks in advance.

Best regards.
