Ok so here is the question, I use a 500cm but not for the normal reasons, I use it for moving wildlife. Most of the time I am shooting at infinity and don't have to focus. I am totally shooting with the sports finder for all of this, so focusing is not needed. The only problem with the 500cm is the sound of it. I would like to remove the mirror and aux shutter in the back of the camera, ( yes I know I would have to put the dark slide in after ever shot to wind the film and shutter). Would it be possible to remove those and still beable to wind he film and cock the shutter?
