I have the 100mm f/2.8 macro on my list, too. I don't think handholdability is an issue for me. I've used my 28-135 for "macro-type" shots and had good success with it at 135mm and wide open. Also, the close focus distance of the 100mmshould make tight shots easy to accomplish. Don't forget that the same framing on the same camera with the 100 can be accomplished from a greater distance. The 100 is more versatile if you ever get a chance to buy a FF body, too.


Between the two, I would definitely get the 100 over the 60. Don't forget, the 100 makes an outstanding, sharp portrait lens as well.
