Filter Holders

For those that may have a 135mm Rodenstock Sironar N lens and are using filters with it, what filter holder system are you using if you resort to using the square slide-in filters for in front of the lens. I've been looking at the Benro filter holder but am having difficulty finding a lens ring for the 135 Sironar N (40.5 mm) so that the holder can attach to the lens. Perhaps one does not exist that small as the smallest I've seen so far is 54 or so mm in size. Thanks.

I use the Cokin holder (and different lenses than you) and I found that I have lots of lenses with threads that cokin doesn't make a mounting disk for. So I have a number of step-up rings to get me to a size that cokin does have--usually it a step up to 49mm. So for you, something like:


The Benro sounds odd if it doesn't go down to 49 at least? Maybe you'll need several steps.

Chuck, you can just buy 40.5 mm filters.... Either Tiffens, B+W.....or try these at $5 a pop.... not much of a loss if the quality is an issue

I use a 40.5mm-->52mm step-up ring and use the filters that I use with my 35mm kit.
Step-up rings should also work with a slide-in filter holder.
