    265mm Ilex Kenro covers 7X17. Don't know about your larger size.

    Anyone use a 600mm Boyer APO Saphir? I bought one in apprehension of going to 8x20, have any opinions? As soon as I get it mounted on 8x10 board, I'll test drive it. It's "supposed" to cover 12x20.

    240mm Computar will also cover 7X17, barely, and 270mm Computar will cover with lots of movement. These are great wide angle lenses for the format if size and weight are a major consideration.

    For my 8x20 I use the Gerogon 14" process lens. Nice wide angle and covers. I also use a Kodak Ektanon 21 1/4" which is very nice and the lenses were both very inexpensive. No shutters but at F-45 to F90 I don't need one.

    Nikkor 450M on 8x20

    I've read and reread the posts but I am getting conflicting reports on the Nikkor 450M being able to cover the full 8x20. Many claim that 11x14 is about it. I have located a 450M in a copal 3 shutter but I am concerned that it may not cover the 8x20. Any final definitive thoughts on this particular lens on the 8x20?

    My Nikon 450M covers my 8 x 20 with room and my 305 G-Claron covers just to the corners, but is sharp across the image.

    Have to agree with Rick. My 450M covers 8x20 without a problem

    Another odd critter you'll probably have a hard time finding but will cover admirably is the Docter 600mm Apo-Germinar.

    a 305 g claron will just cover 8x20
    a couple of the shots (not the vignetted ones) were done with it on the following web page

    I use a 19" artar a lot too

    For some reason there appears to be rare situations that I have been aware of where participants here have indicated that their 450M lenses are exhibiting less than optimal coverage - specifically falling short of 8x20. This is rather rare so I am at a loss to explain this.

    I have two of these lenses and they both cover on 8x20 and 11x14 with the regularly reported excessive coverage.

    It is a always good idea with any ULF lens purchase to reserve sufficient time with the seller to put it on a lens board and check the coverage for your self.
