This may be the mother of all beginner questions, but I've seached all over this site, and having found the answers to almost every other questions I've had, I haven't found the answer to this one. In short, how does one know if a given len s will work with a given shutter? I have to believe that these things come in di fferent sizes and/or capabilities, but I have yet to see an ad that says anythin g like "Barrel lens X, for use with shutter Y." Or is the answer that any compet ent machinist can make any lense work with any shutter?
Thanks in advance David Gardner
