I know that reading the K5's manual is not 'that' easy! A so to little, poorly printed and bound, hard to manipulate booklet is a real pain to read and that you are reluctant consult it.
This is a wrong economy by Pentax and is contra productive!
Good tools only work the right way if they are handled the right way!
That's why I recommend you to look for the pdf version of the manual, it's on one of the DVD's in the box, and go to a descent copy centre and have it duplex printed on A4 formant and bound with those plastic rings system (it cost me only € 5).
So, you will have a nice and easy to manipulate 'book', to search in for the right information, and some large borders for notes, a real pleasure!
Anyway, do reed the manual...
