Hi, I'll admit right off that I haven't thought this all the way through. For some reason I've seen several rather cool shots done with tilt-shift lenses recently; and learning how to use this sort of lens has piqued my interest. It appears to be a rather expensive area to get into, though; and, as far as i can tell, renting a tilt-shift lens is not easily done. Do any of you own a tilt-shift lens? If so, have you felt it was a worthwhile investment? I realize it's not an "everyday" lens; and it's certainly something I'd have to save up for (I'm not made of money, unfortunately). Additionally, what would "rotation" accomplish on a PC lens? I notice the new Nikkor is listed as being capable of tilt/shift/rotation. Thanks!
