I have a quick inquiry question regarding the K-5.

The biggest issue I have with Pentax is their extremely ssssllllloooowwww and unreliable AF system (in the K20d). I'm wondering if anyone has video test samples of the AF's speed and accuracy in the k-5. I'm looking for accuracy in dark enviroments.
I don't know what lenses you are using with your K20D, but if you search for "pentax k-5 af" on Youtube, you should find videos showing AF speed for many lenses. Focus accuracy is a different thing though. But I recently read somewhere that as far as phase-detect AF goes (which is what all DSLRs use) accuracy will never be 100%, more like 70% - for any brand. I don't have any experience with other DSLR brands myself though.
