| Re: Canon EF macro recommendations I have the 100mm and the 50mm with the Life Size Adapter. Each has its place. I'll second the recommendation for the MT24 flash if you can swing it -- it sure makes life a lot easier when you get in really close (especially with the 50mm).
If I had to choose just one I'd go with the 100mm, largely because of the greater stand-off distance. Conversely, depth of field and angle of view are greater with the 50mm.
The 50mm is certainly the lighter and smaller of the two, even in combination with the Life Size Adapter.
I'll point out that the 50mm does not have USM, so it's notably slower to focus when using AF, but if you're doing macro most likely you'll have AF turned off anyway.
A minus for the 50mm is that almost by definition it's more fiddly, since to get to 1:1 you have to dismount the lens and install the Life Size Adapter. It's inevitable that you'll almost have the subject in focus and find that you need to get just that little bit closer, which means breaking down your setup and starting over again with the LSA installed. Or vice-versa -- you'll start with the LSA in place and find that you want to be just a little bit further back, and have to uninstall it, since you can't focus beyond a certain distance with it installed.
Either one's a lot of fun.
