Does anyone have experiance with Nikkor APO f9 process lenses with LF photography, Do these lenses perform at infinity? Are there major focus problem around the edges. Will the 610mm cover 8X10, I found an example on SK Grimes's website showing several different focal lengths (up to the 760mm) mounted in shutter. If anyone has one of these lenses please let me know.

Thanks Dave

A 610mm Apo-Nikkor process lens will cover 20x16!
Do you know the size and weight of one of those babies? I passed up buying one because I knew I'd never be able to use it. Get your camera reinforced.

I have a 360mm. It does very nicely at infinity. On my Arca, I can't use it any closer than about 15 feet, maybe 20.

I have the 600mm Apo and it is stunning! I use it as a telephoto for 4x5 and 5x7, and on larger cameraswhen appropriate. I just did a shot from a bridge of a building that I was assigned. It was the only vantage point to get the shot, but was 1/4 mile away. I shot in 5x7 with two bellows, an extra standard, two rails, a Sinar shutter, and two tripods. The shot is tack sharp and contrasty. Love it! I'm looking for the 760mm now.
