<p>I used a K-1 for a while the other day.<br>
AF seemed fast and sure... and better than my K5ii-s which is saying something.<br>
The day before I had been getting a high strike rate with the AF on the K5ii-s at motorcycle races.<br>
It is technique and lens as John Tran said.<br>
But if action is your AF need then those other makes mentioned above might please.<br>
Overall, the K-1 was fantastic. My lenses took on a superb new image quality.<br>
The body surprised me being 'just right' in size, compact and very solid.<br>
Things like control from smart phone is nice...stick the thing by the kids feeding table and blast away from the next room :)<br>
have fun<br>
