As I have read the ISO change (new button) is no longer a gawd awful two button process. The button is sticky with a time out if the dial is not being turned. Meaning it's now a one finger operation. And I seem to recall I also read in the same user review here on PF the EC button is also sticky with a similar inactivity timeout.
I only have access to the pre-release version of the K7 manual and see no PDF K7 manual so I can't find out for sure.
But the two button system for adjusting ISO on the K20D is about the worst (read flat out poorly designed) setup I could imagine. Nothing on a DSLR should require a two finger operation, or more accurately in remembering the thumb is not actually a finger, finger and thumb combination to operate the function... Still, though, for me the WORST button on a DSLR is a not re-mappable "print" button as found on so many so-called higher end DSLRs...
I suppose it's there for "green box" shooters...more power to them if they are getting the shots they want, but it would be nice if camera's with such a button made it re-mappable.
