I posted the question because I wanted to try the Canon MP-E 65mm micro lens. 1:1 at low magnification, up to 5X at the high end. Strictly closeup use. Nikon does not offer a lens of that design in a macro lens. High magnification macro is not really mainstream. And that lens is an EF lens, never made in other various Canon mounts. There is no doubt that Nikon and Canon lenses have many excellent lenses for sale. To bad Canon dissed its customers by coming out with many versions of mounts so its' customers need to buy the newest lens for the newest camera. Kind of sad? I like being able to use some lenses from the sixties on my Nikon bodies with no adapters. But that one Canon macro lens is the only one of the offerings from Canon that interests me. Since it appears there is no adapter I will just have to pass on that lens. I do prefer Nikon for many reasons, but that is not the point of this posting. We have such a variety of camera brands to choose from, makes for fun times.
