Pretty cool K5 capability!!

Maybe this is widely known, maybe not. I could not find it anywhere in the manual.

I was messing around with live view the other day and set the K5 up as follows:

Live view to contrast AF
AF to constant (C)
Focus select to SEL

When you focus on something, as long as you keep pressing the shutter release half-way, the camera will track it and keep the focus box locked to whatever you initially focused on until it comes close to the outside of the Live view area or out of focus then it re-focuses.

This works as you move closer or farther away as well.

This may be common info, but I found it to be a pretty cool trick. I think it would be great for sports or street photography.

Hmm... I don't use liveview much, but I'll have to remember this!

Thanks for sharing!

While I don't know for sure... I can't imagine that it doesn't.

This also works in non-liveview mode, or am I missing something extra-special here?

Yes, AF tracking is nowdays considered a normal behavior.

I just tried this with the same setup except no live view and the focus indicator does not track/follow the last focused on item. So, no I don't think so.

Thanks for bringing this up again. IMHO it is not widely known. I mentioned it once or twice, e.g. in the context of questions if K-01 would have AF tracking.

IMHO, object tracking is a side effect of PhotoNation's face detection library built in into the firmware which tracks faces by default. As soon as the target is identified, this library must be able to track it.

Unfortunately, at least in the K-5, it is unreliable (looses tack) and slow. I don't think t is useful in real life. I never actually used it...

Yes, I agree it is not perfect and probably not functional enough for any real world application. I just found it to be cool.

Thanks, also for the technical explanation of how it works!!! Extremely interesting!!!
