I have a IIIf, and a Bessa L, with the 21 Scopar. Very differant beasts, but I have really been enjoying the Bessa combo. The outside meter, and the super wide lens with its long depth of field make an excellent pair. The lens is very sharp, and there is little need to hold it to my face while shooting in a crowd. I used it today at an Octoberfest event, and it was easy and natural to shoot.
