Hi all,
Does anyone know the thread pitch and filter size on a 14" Wollensak Veritar lens? I took it to a local camera store yesterday and tried to measure it with their caliper which was a little broke. The diameter appears to be ~100mm and the pitch on the threads is much narrower than the pitch on the 610mm Apo Nikkor process lens that I brought with me for the same purpose. The Nikkor has a filter diameter of 95mm and we screwed in a circular 95mm filter which they happened to have. They didn't have a 100mm screw-in filter nor any step-up/down rings in that size so I'm not sure what filter size it takes or if any filter ring will thread on the lens. I use this lens for soft focus images and need to use a ND for outdoors shots when the sun is out (with heavy fog lighting I can get by without one). Currently I'm placing a 100mm 3-stop Schneider rectangular filter by hand against the front of the lens but would like to use a Cokin X-Pro or similar but would like to avoid the cost of the Universal Filter Ring: http://www.bhphotovideo.com/c/product/168533-REG/Cokin_CX499_X_Pro_Universal_Adapter_Ring.html Any input or suggestions is appreciated.
