Ok yes I know I was just looking for one of these. Well the one I got was a dud. If your interested see (there was a url link here which no longer exists).
So I'm once again looking for a 210mm 5.6 or even 180mm 5.6 plasmat to use for 5x7. Something with 67mm or smaller front threads.
180mm Fuji W f/5.6. 67mm filter. slight schneideritis on mount of front elements, otherwise very clean. In a Copal, solid speeds. Drop a PM if interested.
