on 400-500mm lens again (filter thread question)

[Janko Belaj]

Well, one more think came to my mind - I have fine collection of filters in thread size of 52mm (kind of heritage from nikon system) and I have all my "everyday lf lenses" equipped with 52mm thread (step-up rings for smaller lenses, that exclude S-A). Is there any "not-so-expensive" lens with 52mm filter thread? We were talking about Apo Ronar 480, I have searched around to find what it's thread size might be but had no luck. Can anyone help? tnx.

The Rodenstock 11 480mm Apo Ronar takes a 67mm filter. It is also a big and heavy lens in a Copal 3 shutter. The Fuji f12.5 450mm Compact takes a 52mm filter is small light and is in a Copal 1 shutter.
