I use 48mm in a S VII push on adpator for my Kodak Commercial 150mm for 4X5.
A quick reference for finding the filter size on most any lens is the listings @ KEH Camera.
The filter ring size is identified with parenthesis '( )' for most lenses they list. Very handy!
Random KEH listing example for a Canon lens using 48mm filter:
Canon Manual Focus - Fixed Focal Length Lenses
135 F3.5 FL BL (48) 35MM SLR MANUAL FOCUS TELEPHOTO LENS
KEH Camera, Georgia, USA:
Oops, I have a step up adapter for them on mt TLR.
Canon Super8 movie camera.

Canon 50mm f1.4 rangefinder lens
