Q: 10. On a tripod, if I acquire focus, then unmount the lens, put the 10stop filter in, re-mount the lens... will the camera regain focus where it was.... or will I somehow now need to refocus through the 10stop filter? If I do need to refocus through the filter, has anyone had any success focusing through a 10 stop filter on a mirrorless camera?

A: It would best to pre-focus the shot then record the focus settings as you may need to re-focus the shot once the filter is attached.
