Well there is only one answer to the thread title: RedCat 51 APO 250mm f/4.9 . I was using the lens that was regarded as the best at the time for either nikon or canon. The Redcat makes it look like a plastic kit lens. Super sharp and flat field. M48 threaded you just buy with whatever adapter you need to your camera body. Couple of samples on my astrobin page.
