[QUOTE="aroy, post: 360717, member: 16090"] All macro lenses will give 1:1, but at different lense to object distance. The reason for recommending 60mm is . It is linear geometrically and sharp end to end. So it is the easiest for technical copy work, where geometric non linearity will not be tolerated. . The ES-1 is a tailor made solution for the lense. That and a ring for DX is all you need to copy slides (and negatives). Other solutions may be better or more versatile, but this combination has the simplest setup and a practically no brainer execution. . 105mm the most popular focul length for macros, suffers from CA in certain cases. That means that you have to be extremely careful while copying. [/QUOTE]
