I have five Canon FD S.L.R. bodys,(3 new F1's, an EF, and a T90) and two Mamiya T.L.R 6X6 bodys (C330F) and a set of lenses all of which that I use almost every day especially since I retired I've owned the vast majority of my equipment for more than 30 years. I realized many years ago that having more equipment than you actually use on a regular basis is counter productive because it's the more you have to protect, insure, maintain, and worry about.
