Coverage of a Konica Hexanon GR II 260mm?

[Scott Davis]

Anyone have any idea what the coverage for a Konica GR II 260mm lens might be? Would it cover 11x14 with movement? anything bigger (12x15)???

8x10 with more movements than I can muster, but you'd need to ask the lens (i.e. shoot with it) to see if it meets your expectations.

So it MIGHT cover 12x15 with little to no movement. I'm just trying to figure out before I cut a lensboard if it would be worth the effort.

Get some foamcore or matting board, with some spacers around the edge to fit it to the camera for use. If it works out, you know you need to get a permanent lensboard made. If not, you just spent less than $5 and have plenty left over to test several other lenses.

Jim Galli sed, back in 2007, that it fit 11x14, but did not mention how well/movements

Works on 7x17!

FWIW, the 210mm doesn't...

When you say works on 7x17, does it provide any room for movement, and how stopped down are you?

Scott, It's odd. With my tests (4 sheets so far), F9 and F45 don't make any difference. I had minimal front and rear movements (Folmer and Schwing 7x17) and it clipped one corner, the other edges were clean. Another exposure at F9 (I forgot to close the lens down), and all 4 of the edges were all clean (no movements). I'm wondering if my homemade foam board lens board is not centered correctly or if the bellows are blocking the film with movements.

So I can say, that F9 (wide open) covers 7x17 with no movements. I've got to figure out why I'm getting a clipped corner.

Here's an example of what I'm talking about. Please forgive my processing. I'm trying to work my ULF tray processing out:

Have you considered using a Jobo 28XX drum extension set?

I do most of my 7x17 in one (2 sheets at a time).
