Hi all
Today I wanted to test the focus micro-adjustment function, but the camera does not allow it with the 200-600 mounted.
Is that correct or am I doing something wrong?
Why can't focus microadjustment be done with the 200-600?

The micro-adjustment function is only intended for A-mount lenses when using the LA-EA2, LA-EA4, or LA-EA5 adapters. E-mount lenses should not need to be micro-adjusted as there shouldn't be any focussing errors. If you do have focussing errors then I'd suggest reaching out to Sony support as there might be other issues with your lens or camera.

In general mirrorless cameras don't need the microadjustment. In dslrs, it's there to compensate for any difference in path length between the optics to sensor, and the optics/mirror to focusing stuff.
