Hello-

I have a K-x that I love, but want a camera that can autofocus during video recording. I am considering the K-50, and I realize there is no continuous autofocus on any Pentax SLR.

My question is, in practical terms, how well does the autofocus during recording work? My understanding is that if the subject moves, you can push a button and the camera will refocus on the subject.

Basically I want to know if it works well enough to warrant spending the money, or should I just keep my k-x and buy a video camera.

If you're just going to be using the AF to re-focus after zooming or panning, then the K-50 should be sufficient. The AF isn't really suitable for moving subjects, though.

AF during video recording is a sad sad sad joke which should have been left out entirely until such time as they actually can make it work to a point whereby even the most carefree users would actually use it and find it remotely acceptable.. It's quite useless for any purpose really even with a HSM lens, it hunts and hunts then finally finds something, maybe if you're lucky. With a screw drive lens it's worse and your movie audio will be totally ruined by the sound of the AF motor grinding away.
