Hi Guys,
I bought this Ansco Commercial 8x10 camera, and the lens that came with the camera is a Goerz Celor Series I b No. 5, 10 3/4" F5, I understand that this is a dialyte design, with 4/4 construction, so it should be about 45 degrees, similar to Artars? Will a 10 3/4" Celor cover 8x10? I need to find a lens board before I can test it myself on my Ansco.
According to CameraEccentric site, Celor's coverage angle is 64 to 70 degrees, and a No 5. covers 8x10 at f16. Can a lens of dialyte design coverage ~70 degrees?

Thanks!

BTW, this is a HUGE lens for a 10" lens, very heavy too, with brass barrel, front and rear groups are the symmetrical I think.
