I feel your pain ... I thought I was going to wear out the threads of my Bronica mounting and removing filters a year or so back.

There were some folders in the 1930s that had a yellow filter hinged to the lens mount. For my latest IR foray I used a TLR, an easy solution.

Any chance you could find a push-on filter adapter for your camera of choice? Admittedly they are becoming rare, but I see a few go by on ePrey.
