Not using this baby much these days. But if you're into macro, it's the only lens that does 1x to 5x lifesize (without extension tubes etc). I'll post some pics of it and macros taken with it over the weekend.

To give you an idea of the magnification, here are some shots I've taken with it. Notice the one showing my finger for scale (this probably wasn't taken with this lens, can't remember) and the red nymphs. The shot of the red nymph on leaf is the same size as the ones in shot with my finger, and that is not a cropped photo.
