Thanks! The vignetting is a Lomography thing, I think; it could be corrected, but I'll probably keep it that way. I'll upload another example a bit later (btw. same piece of lint, same need of rescanning - but there's no time for that today). The lens also distorts quite a bit, but that's all part of the "fun" of using a 21mm-e that's put in front of a el-cheapo automatic camera. Considering all that, I'm pretty happy - or would be if the camera (my second one - the first had serious issues) would work reliably, which it doesn't - it needs really careful handling to avoid issues with the film transport and release, which somehow goes against the idea of wide-angle street/urban beast. I like the results enough to keep it, but wouldn't really recommend it in spite of its merits - too capricious.
I'll use it occasionally because it's quite liberating - but not often because it can be annoying.
