As posted here... one question regarding my new Sinaron 55/4,5 MC (green stripe, Copal 0 shutter) :
I bought it to recover some wide-angle possibilities with 6x9cm shots. I don't mind a little illumination fall-off, in fact I quite like it, but if it goes down one stop or more, then no. I don't use any with my Schneider Super-Angulon 75/5,6...
Rodenstock center filter necessary ?
