I have a bunch of Series slip-on filter holders but none fit my 135mm f/4.7 Wollensak.
The shutter is a Graphex on a Crown Graphic lensboard.
I tried Series 5 and Series 6 slip-on filter holders. The Series 5 was about the same size as the ring around the lens so that didn't work. The Series 6 was way too big.
Or am I going down the wrong path... am I supposed to use a screw-in filter?
Any help would be appreciated.
Thanks.
