Ok, so I have a can not turn down deal on a Nikon D80, but I very badly would like to use the Canon MPE-65. How do the converters work between the two?
Sure, I'd prefer to have a 40D, or better with that macro monster, but hey, economy and all...
Oh, right, noob.
Since the MP-E 65 is a macro-only lens (!), starting at 1X on a Canon body, it shouldn't really matter, as you can't focus to infinity with the MP-E 65 anyway. You just get a slight additional magnification, in the order of 5 % or thereabouts (caused by the thickness of the adapter plus the extra mount to sensor distance). So instead of a 1X - 5X macro lens, it now becomes a 1.05X - 5.05X macro lens instead. Furthermore, it is an MF lens, so that doesn't make a difference either.
With any other lens it would be a real problem, as you can't focus to infinity, due to the larger register distance of a Nikon body.
You'll still have 1 problem however, unless the adapter takes care of this, and that is closing the diaphragm down to the required aperture: with Canon this is taken care of by an electronic interface, so I don't know whether that is going to work on the Nikon, unless you do the aperture preview trick, i.e., mount the lens on a Canon body, close down the aperture in, e.g., AV-mode, press the aperture preview button, and while keeping it depressed, unmount the lens, and then mount it on the adapter and Nikon body. Focusing will become very cumbersome however, as the image will be even darker with the aperture fully closed. To me this would really not be an option, I'd prefer to use a Canon body in that case maybe a 450D or a 1000D - both are excellent cameras. Another option is a used 30D, if you prefer a larger camera, or even a used 400D.
The advice of getting a cheaper Canon body that was given above, is therefore IMO the best way to go, with the MP-E 65. Also, if you are new to dslrs and/or macro, I'd suggest you start of with a slightly less challenging macro lens, like the Canon EF 50 F/2.5 CM, the EF-S 60 F/2.8 or the EF 100 F/2.8, which all can focus to infinity besides doing macro stuff.
Or get the Nikon body with a decent macro lens with Nikon mount, like the Nikon 60 mm, 105 mm, or any of the 3rd party ones from Tamron, Tokina or Sigma.
Kind regards, Wim
