Not sure where I should have put this question, but here goes. I use a UV filter on all my lens. I typically leave them on after using them. This creates a situation where the lens cap is continually popping off, sometimes in awkward situations. When this happens the lens is still protected, but not at the same safety level as when cap is on. Of course the solution to this is to simply unscrew the filter when I am finished with the lens. But on some shoots, like at the bird rookery today, I was changing three different lens back and forth continuously. Should I just resign myself to screwing and unscrewing the UV filters and exercise my inner patience (at the chance of missing quickly developing opportunity) or is there another solution?
