As I wrote here before, I recently bought a Horseman VH-R with 3 lenses: a Horseman Super ER 75mm, a Horseman Super ER 180mm and a Topcor 150mm. To fill up the gap between the 75 and the 150mm lenses, I would like to buy, in time, a lens in the range of 100 to 120mm .
All these lenses have a Copal 0 shutter or similar. When I look at the website of Keh, I see mention of "35 mount, 34 mount, 42 mount" and I also see lensboards with a 35, 34 or 42 hole. What does this mean? Is not every Copal 0 shutter the same diameter?
Thanks for your help,
Frank
