Do you need or want an ultra fast lens? How much of a difference is there in practice between images from f1.2 or f1.4 or f2 lenses?
This video shows how one classic ultra-fast lens performs at f1.2, f1.4, f2 etc., and also wide open versus stopped down.
The video should also be of interest to anyone considering a Tomioka 55mm f1.2 (My version is the Auto Revuenon).
I've compared the lens with two other Tomioka made lenses - the Mamiya/Sekor 55mm f1.4 and the Yashica Auto Yashinon 50mm f1.7, to see how they perform wide open.
