Hello, everyone I just joined, I use Mamiya TLRs, A C330f and a C33, with 55,80,135, and 180mm lenses, I've used them for more than twenty years I recently got both the cameras a C.L.A, although I've never had any problem with them I thought it was about time, especially since they were second had when I bought them, the C33 was pretty old 20years ago,and I should have had it done then but it just kept going It's built like a Russian KV1 WW11 heavy tank and will probably outlast all of us.
