The Fuji 300mm C f8.5 is certainly NOT a telephoto design... and I do not desire to debate the terms. =)
That being said I did recommend it to Stone for use on his camera, a Toyo 45AII. I have that same camera and the Fuji 300mm C f8.5 lens. I forget the exact minimum focus distance but I can set up my camera with this lens in my living room and focus on the lamp by the wall. I'd have to remeasure but the living room is small, the focus distance is somewhere between 10 and 20 feet. This is the main reason I bought the lens and sold my 305mm G-Claron. The G-Claron requires MUCH more bellows draw.
I cannot and will not comment on Stone's own measurements.
