Eric,

Ran out of steam after about 15 pics, but there are some nice ones there.

Two thoughts about K-5 AF:

First, make sure you've adjusted the camera for the lens.  This can make a big 
difference.  There's a technique that exploits the moire generated when a 
target of concentric circles on a computer monitor hits your sensor in perfect 
focus that I have found useful (unfortunately I can't find the file right now).

Second, on the K-5 (and K-7), the central AF area is that =entire= center 
circle in the viewfinder--it's much larger than the little red square.  That 
can make things tricky.

Cheers,

Rick
