The big mini is a high-quality point-and-shoot camera similar to a yashica t4 and olympus stylus epic.
If i remember correctly, the lens is a 30mm instead of the fairly standard 35mm of the others.
It has a nice slim profile. The shutter is quiet, but the film advance is loud. (at least on mine).
Other than that, it has pretty much the same specs as the others.
It is an enjoyable pocket camera.
