The AF drive speed is similar in 60 and 100 macro lenses, on the upper end of their FL range. They both allow excellent AF on very fast targets even in very poor light conditions like in the images below.
The key differences are:
* My 60 is sharper than my 100, but that\'s largely academic...they are both plenty sharp.
* Any application differences between them are consistent with the difference in FL.
For example, I use the 60 as a very dependable walk around prime. The 100 is obviously better for birds, etc..
