On the left, it's a Bausch & Lomb 12" projector lens, f7.7, wide open for /3.
And the vertical is a Rodenstock APO-Ronar 360mm barrel lens, f9 for /2.
Both taken on a Triple Victo Whole Plate camera with a new reducing back I just made. Packard shutter.
I'm interested to hear if'nwhy people prefer one or the other 'cos I can't make up my mind between 'em !!
