Dead right Tom,
what a lot of people don't think of is that the "camera shake" factor increases
too - I suppose by the same factor as the frame is cropped.
I was thinking of the 12mm because my shortest lens I have is the 18mm end of
the EF-S 18-55mm zoom supplied by Canon. The crop factor of both the 20D and the
300D is around 1.6 so my widest WA is at present effectively a 28mm.
cheers
Douglas

Even if the DOF makes it acceptable sharp, it will be a longer focal length, effectively! Most people don't realize focal length is increasing as you focus closer. E.g. 50mm refers to focal length at infinity. In other words, the normal lens has 50mm focal length at infinity, or 100mm focal length at 1:1.

I don't think so Dave , I don't think lens recycling goes that far,but I am thinking of getting an LTM to EOS adapter and messing about a bit with some old Canon screw mount mid-range telephoto lenses for close-ups. Does anyone know what happens if I fit a Voigtläender 12mm or 15mm via one of these to it? would stopping right down take the focus range to infinity? or am I not thinking straight and overlooking something on this idea.
