Without the CF I believe it is a flat field lens. I haven't seen FF on their lenses or in the advertising. Item 37512 is listed as a colorplan-p 2 2.5/90mm and item 37513 is listed as Colorplan-p 2 CF 2.5/90mm. I think your lens is a flat field lens. If you have a badly curved slide or a glass mounted one, you should be able to see a difference. Problem is that a CF lens will not always project a cardboard mounted lens sharp, but it should be apparant with a FF lens. Dick Hemingway Norman, OK >
