$850 for a superzoom?
Ah Leica. It's like a religion with a fanatic fan following, but to outsiders, they seem a bit nutty. They are known for their legendary craftsmanship on optics. However, like any superzoom, this camera has an incredibly tiny sensor(1/2.33"), which can only capture a small fraction of the detail a standard DSLR, or APS-C sized sensor can. As a result, the sensor cannot resolve the finer details of high quality optics, and thus any possible "legendary leica" optics becomes a moot point in this case.
You would find much better image quality in a DSLR for $850, or a P&S with an APS-C sized sensor. If you really need the incredible zoom capabilities, there are many superzoom lenses available that you can get with the DSLR and still come below $850.
