Traded in my istd and My new K-5 just arrived. Still going throght the front pages of the manual... Wish me luck !

Welcome! hope you enjoy your K-5! I downloaded the manual a week before I received my K-5, so I was well read when it arrived There's a lot to read, but lots of it is very straight forward and the menu's are quite intuitive. Just need to figure out what things do or do not work in certain modes or when certain things are selected already etc.

Welcome to this fine group! The K-5 is a very good choice. You have a lot of pleasant camera experiences to look forward to.
