filter mounting on Rodenstock Sironar 360/f6.8 questionsgreenspun.com : LUSENET : Large format photography : One Thread |
I would like to know the filter size for the internal end of the Rodenstock Sironar 360/f6.8 lens (the pre-APO version).Having looked at it, it does not appear to have threads. Is it possible to get an adapter and mount a standard filter size? It looks to be about 80mm (82?).
Has anyone figured out a way to do this?
Thanks,
Derick

Yes you can mount a filter behind the lens. But you will introduce a focus shift of 1/3rd the thickness of the filter so you must focus and do your corrections with the filter in place.The factory does not recommend doing this. you have the pre Apo N version (Sironar N not Sironar) then I can mail you the specs. To do this I need a mailing address. You can e-mail it to us or call us at 973 808-9010 x15 or request it on our web site www.hpmarketingcorp.co
