I think it's fair to say I wing it. I have been changing the mount to accomodate Canon EF still lenses, and my employer's Tokina Vista PL lenses, both primes and zooms. I haven't noticed any issues, but I don't do anything special to make sure back focus is okay. I typically use a 7" Atomos monitor.
Is there something I should be doing to be more careful about back focus, or will I generally easily see a problem.?
