My K-5 - A few questions before I post some snaps...

[seqo]

I received my K-5 and Sigma 50mm 1.4 on Friday and happily spent the entire weekend playing with it. Resultantly, I have a few questions:

1. I am unable to find the current Firmware Revision/Version listed in the Camera Menu. Did I miss something when I read the manual? - Ok, read the whole sticky re: Firmware and found that you can get to it by powering on + holding menu button. Is this still valid for the K-5 though?
2. The camera makes a rattling (sliding & 'clack'ing) noise when I turn the camera from side to side. Is this normal?

Hope someone can answer these questions.
