I have both this and the M100/4 Macro, and regard this as the sharper of the
two. Whether the focal length is as useful is another matter, though, as it
gives rather close working distances when working "in the wild". The 100mm
makes it easier to get lighting in, or not to frighten the wildlife too
much. Where it once shone was on the copystand when the original artwork
was around 8in x 10in and bigger, and the 100mm called for too much height.
That sort of copywork is now mostly done by scanners if the desired result
is a print, so unless you're aiming to get 35mm slides out of large (A4 to
A3) artwork it might be better to look for a 100mm (or 90mm depending upon
the brand).
Regards,
Anthony Farr
