Which camera models did I have, and got rid of? Hummm. Rolleiflex. Leica 3f. Leica M2r. Forty years after unloading my Rollei I have a "new" one, a f3.5 from the 1960s. I am not happy my M2r got away from me.
By the way, I used the Rolleiflex and the Yashicamat professionally and both gave very sharp photos. While scanning both (the Rollei ones from the 1960s and the Yashicamat ones from the 1970s), I noticed both camera gave fine, sharp negatives but the Rollei negs were richer and deeper. But the Yashicamat is a first class camera. I have two of them, one with German lenses.
