Are you sure?

I ask because I sometimes use a 10.16"/9 Cooke Copying Lens on my 2x3 Century Graphic, maximum extension around 196 mm. The trick is to hang the lens on an LTM tube on an adapter on a #1 shutter on the board. Focuses usefully close, too.

Oh, yeah, the lens is TTH's interpretation of the Apo Tessar, isn't at all telephoto.
