I own a tokina 12-24 and always found the close focus distance (about 1 foot) to be really intriguing idea for macro work, but the photographer side of me really dislikes the distortions. Most of the field work I do is usually at night, which means I usually have to do fairly close up shots with strobes/reflectors and such and eliminates the option of using the wide. Looking at some of those incredible shots, though, makes me think I may have to start using it more.
