Menu button customization AF/AE-L button operation establishment while video recording when the AF/AE-L button is pressed.
Basically "動画撮影中" means "in the middle of video is being recorded," so unlike the K-5 and earlier cameras, the K-01 will be able to focus when the camera is recording. The question will be if it is continuous while the button is down, or if it will lock on and then stop until the button is let go and pressed again. My guess is the latter. Either way it's a nice improvement over existing cameras.
