Please note that this review isn't just me ripping on the Leica mini. If you find one at a good price, by all means buy it and you should be pretty happy. Here's the thing about the Leica Mini though... its a great compact, but it doesn't hold up when compared to the Mini Zoom(in my opinion). The Camera itself is awesome. Its fun to shoot, and feels surprisingly solid for a plastic point and shoot. It also focuses pretty quickly, and as far as automatic film cameras go, its not that loud. Its also significantly smaller than the zoom, so it has that going for it as well.
To me, the problem is the lens. Its actually a really good lens, especially by point-and-shoot standards. But its NOT as good as the mini zoom. The Mini zoom has a lens that is just as sharp, and while you sacrifice half a stop or so at its widest setting, you get much more versatility in a relatively similar package with the mini zoom. The other problem is its lack of control features. While the mini zoom has a variety of modes to choose from, the Mini only has flash settings, like the majority of consumer point and shoots from the time.
Because of these issues, I consider the Leica Mini to be a dumbed down version of the Leica mini zoom. It does have one feature that I like though, which is that mine tended to slightly overexpose photos by around a stop, making scanning much easier on flatbed scanners like my v600. This could vary from camera to camera though, so take it with a grain of salt.
All images were shot on full auto mode with Kodak Ultramax 400, and were scanned with an epson v600
