After dropping all my K10 gear earlier this year, I thought I was going to be defecting to the MFT camp when the GH2 hit; but the more I see the K-5, the more I can't bring myself to do it. I just wish there was more K-5 material out on the web (withholds Pentax marketing comments) it's sad when you compare the amount of info between the two cameras that is available (seeing as how the GH2 is hitting at least a full month later). Please Pentax, fuel my addiction! (and curiosity)
I have to say though, it's looking more and more like I'll be joining the club
(if you are wondering why the odd pairing, full VDLSR / DSMC functionality matters to me)
