My favorite 8x10 lens is a 355 red dot artar that I got off a process camera. It was a barrel lens that I had custom fit to a shutter. I use it primarily for still life but it is great for portraits or nudes. I am not sure how it does with fine detail at infinite because I have never used it for that kind of photography. In studio it is perfect and with a diopter on it is great for larger than 1-1 still life as well.
