A great first person review of the Canon EF 100mm f2/8 MacroUSM Lens by Darren at Digital Photography Blog. He captures some great shots of bugs in his lawn to show the quality of the zoom lens that Canon has come out with for the Canon EOS 20D.

100mm gives plenty of working length and allows you to get in nice and close. Focusing is fast (although it takes some practice to get a bug in front of a distant background). Contrast and sharpness seem good although I’m looking forward to using it on the weekend with my tripod attached.

The lens is a little bigger than I was expecting but not as heavy as some of my other lenses. I’ve heard it’s a very good portrait lens also so this one might be regular feature on my 20D. Digital Photography Blog
