Someone in the Wide Field Ektar thread mentioned the 21.25" Ektanon and asked what coverage it provides, so I thought I'd start a new thread.

There's very little available in the archives on this lens. I've read that the older version of this lens, the 21.25" Anastigmat, gives more coverage than the 21.25" Copying Ektanon. I bought a beater 21.25" Anastigmat in barrel as a potential 11x14 lens, and have a spare Copal 3S, but I, too, would like to hear whether it's any good and how much it covers before ponying up to have it mounted.

I've done the stand-in-a-closet-and-aim-at-the-window coverage test, but other than verifying that casts a large circle of illumination and actually makes an image, I don't know what its limits are or whether it's sharp enough to bother with. Anybody use these lenses?
