I just got mine canon 100mm macro lens today, It is brand new I ordered it from adorama on line, have not yet take it outside for any photos shooting, just put it on my canon 40d, it is very fast focus on any subjects near and far, but it making noise when it does, not big noise, it is sound like the usm runing try to focusing on the subjects, also the focus ring kind of loss a little to left and right, it is not firm like my other lens. It is heavy too.

the auto focus is very quick between the subject and the background, it keeps focus on the background more then on the close subject-the spider, I have to turn off the AF, but I have problem to focus on the spider myself.

here are some other shots.

How loud it is of course is very subjective. Mine makes some noise as it searches. In low light, it searches alot. Most macro guys will say to use manual focus to alleviate this. AF apparenty doesn't work as effeciently for macro work. Food for thought.

Where your focus ends up using AF is a function of the camera, not the lens. As was stated by others, just learn to not use AF, instead manually focus, then fine focus by moving your head just slightly. With a DOF about as thin as paper, you will be a more effective faster AF motor than the camera's AF system.

It not very noise, but I can hear the motor turning when its in search, I can say you won't hear it if you stand 1 or 2 steps next to me. I have 4 canon USM lens, they don't make that motor turning noise.

Thanks for the info, I will try using manually, only problem I have is that I can not keep myself focus on close and far away subjects, I keep thinking is it clear when I turning the focus ring, maybe I need a pair of glasses.

Mine is a bit noisy - both in AF and MF when you change focus, kinda a grinding sound like the focus parts are a bit tight and binding up. I'm over it, it works fine and the quality of images that come out makes up for it :)
