The AF on my K5 is faster and follows a moving object better than my K7 did, I'm happy with it.

With the current price the K-5 is a steel.

I think K-7's AF was a huge improvement, and K-5 is better, although other features of K-5 warrant more attention (high dynamic range, etc.)

K-5 AF gets kicked on the balls by K-7 in low light... sadly. Atleast this is what I experience. The low light front focus issue is quite huge for me.

The high iso performance of k-5 is kind of crippled by the worthless AF.

Maybe will send my k-5 for repair - if there's anything to do about it...

AF-C is better on K-5, definitely. I also had more accuracy issues, but maybe I only didn't test the K-7 long enough. I had it borrowed only for few days and it took me lot more time to realize that sometimes K-5 doesn't focus right.

I'm throwing this in for any current K10D/K20D owners thinking about the K-5. Put bluntly, you will be SHOCKED at the improvement in AF speed and accuracy, even in lower light. If this hasn't been the case for you if you're already a K-5 owner, then perhaps you have some kind of defect. I've tested AF on three different K-5 bodies, and the remarkable results have all been the same. There's my $0.025 worth, for the record.

Sure, the difference is huuuge. I kept the K10D as a backup body and whenever I end up taking it with me, I'm shocked by how much slower it is in comparison.

I was actually on the edge of jumping ship after trying out the D3 and EOS 1D in low light for a while. But I decided to wait and now with K-5 I'm quite satisfied. Some time ago I compared it against a D700 in a pub and the speed and accuracy was quite close with K-5. K10D would be beaten badly by the big Nikon.
