I rationalised my equipment many years ago and sold what didn't make sense as a practical usable outfit, now my 35mm S.L.R. bodys are all Canon FD and so are my lenses, all my lenses fit and work correctly on the bodys I own, my two Medium format Mamiya T.L.R. bodys work with all the lenses and accessories I have for them too.
I'm very happy with what I own and have no desire to acquire anything else, any spare money I have had to spend on my photography in the last two or three years I have spent on getting all my cameras professionally C.L.A'd because I have had them all more than twenty five years, and they were all second hand when I bought them, so all my gear is in tip top condition now and I can just enjoy using it.
