Here is a deal for the Shutter cleaning club: Wollensak 10 inch telephoto F 5.6 with perfect front and rear elements, no flaws whatsoever and a shutter that works in all settings EXCEPT B and T.
Triggering it on both B and T elicits an opening in the 1/10 sec speed range, and the lens does not stay open.
All other speeds appear to be accurate.
The lens board is included as well as a Schneider rear cap.
A 55mm Skylight filter is available for $10
Because of this, the price is $125 plus $8 shipping.
A freaking STEAL!
