The problem with screw-on filters is that you need to focus first and then put on the filter, then for every new shot go through the "screw filter off - focus - put filter back on" routine. That's the system I have, and it works, but it can be a bit of a pain. It would be simpler just to be able to drop the filter into a holder and take it out again as needed.
New to long exposure and don’t understand why you would have to remove the Nd filter and refocus each time? Can you please explain why?
