@rayvonn That's a very interesting question. As a RAW shooter, I'm pretty much aware of the fact that this lens distorts mightly, so one could see it as a sort of "narrow" fish-eye rather than a serious wide-angle - and its images certainly invite that kind of approach since they can get very dynamic indeed. But actually, even though I tend to frame rather consciously if I have enough time, the lens makes it very easy to concentrate on parts of the frame - it's as if it invited you to concentrate on your main subject and actually include serious amounts of other things into the image without really giving them a second thought because most of the time, the way they are rendered is interesting or at least unobstrusive - that's not always the case with that kind of lens; my other 24mm (a FF lens) demands more attention, but it also renders more predictably. With the 7.5mm, I do mind foreground, corners, lines and boundaries a lot more than with the 12mm - I often go for an overall look or impression instead of a specific subject. The other way I use it is as a sort of extreme street lens, but those images have more fun value than quality.
