During the 1970's I owned (2) black M5 cameras with 21 f4, 35mm f2, 50mm f1, 50mm f2, 65mm black 3.5, 90mm f2.8, 135mm f4, 180mm f2.8...very rare, 280mm f4.8 in foc rapid, Visoflex III and bellow II with compendium and a v35 enlarger with 40mm focatar and 50mm focotar II The economy finally forced me to part with the equipment. The equipment was totally satisfactory. I have no experience with any of the other models listed.
