My body has micro adjustment, but only one value per lens.

When I used FoCal on the 50mm it showed that it needed drastically different fine tune values at different focusing distances, so without the dock it would have been impossible to fully correct. With FoCal and the Sigma dock, I'm able to set the different fine tune values at different focusing distances that I need, but I still feel like it's a bit off at certain distances.

So after adjustment in FoCal, is that just specific to 1 body (the one you did the testing on) or any body once you've done the fine-tuning?

The 85mm and 24-35mm were both fine. I haven't fine tuned the 24-35mm at all and FoCal showed that the 85mm only needed a tiny adjustment to achieve best focus.
