I've been assembling one and a half Pentax 67II kits. As we divide our time b/w NY and AZ, my plan is to have the same lenses at each locale and just transport the body between them. I've obtained the lenses and have a problem. I wanted and found on eBay two 55mm/3.5f Super Takumar lenses. Unfortunately, only one came with a UV filter. I always put either UVs or skylight filters on all my lenses for the prophylactic protection. Alas, I cannot find a source anywhere for 100mm filters. I struck out at my favorite vendor (Filter Connection) and even at B&H Photo. Does anyone know where I can find a 100mm UV filter?
