Judging from what I have read, the Nikon 450 M covers 12x20, but the Fujinon 450 C does not. I am wondering if the extra coverage of the Nikon 450 M over the Fujinon 450 C is of much help with 11x14 and 8x20. Would someone who uses the Fujinon 450 C for these formats tell me if the lens ever leaves you wishing for more coverage?
