Originally posted by Ben Searle I've had a K5 since it came out and now thinking of a K3. My favourite lens for action photography (mostly of leisure cyclists) is the 70mm limited, but also the 21mm. Focus can be bit slow and not always accurate so I'm wondering how much better these will perform on the K3
I've experienced inaccurate focusing with the DA 70 on the K5
because of the large area of the center focus point (the only one I ever use).
The focus can then go to the background instead of the subject.
Supposedly the K3 points are smaller, which ought to help with this issue.
