K-3II AF-C and Lock question

mattieyp3 · 09-23-2016, 10:25 AM

Does the K-3ii have a setting for how long the AF Continuous will lock? For instance, I want continuous AF but I want it to lock for a brief second or 2, then reactivate/reacquire an accurate focus point, and lock for a second or two. I want this to happen all while I am holding down the back button AF button. In addition, if it does have this feature, should I choose FPS priority or AF Priority? I'm shooting sports... football, soccer, volleyball, all of em.

Option C3-18 (hold af status) says how soon the camera will try to refocus once it's lost focus. Default is off (although there's still some lag) and then you have low/med/high. I usually have mine on af priority for the first frame and for the following ones, but I think there's room to experiment with fps priority if your subjects are not going towards or away from you.

Oh, is low long or short?

I've used anything but off infrequently, I just put it on low or medium and didn't really compare. If you end up testing this more systematically, I'd be interested to see the results

I tested it out. "AF Hold Low" means the AF lock is held for a low amount of time. "AF Hold High" means the lock is held for a much longer amount of time before reacquiring focus. Enjoy!
