I have sold very little of my gear, that is why I have way too much. I did sell my Konica T and lenes including the 57mm 1.2 to buy a used Nikon F with motor drive, then sold the F to buy a F2, then the F2 to buy a F3P. Other wise I still have my Kodak Retina IIIC big, gift from my aunts in 1965, my Pentax Spotmatic, got it in 1966, have all the lens, after the move to digital and every one either sold or donated film bodies and lenes I picked up Miranda, Petir, Topcon Auto 100 and Kowa for just the sake of having them. Still have my Sigma digital gear, the film camers suffer the oragne glow of death in the viewfinders, but then bought Minolta and Sony, have all the lens and bodies. Then added Minolta MF gear. I am to the point that I will either start to sell some, but most likely dontate.
