I have recently bought an A7II and I am loving it. I have never got into video before, but would like to give it a go. I have a question about the autofocus in video though.
When in video mode I am locked into either AF-C or MF, but when I press the shutter button in AF-C it locks focus like AF-S does in stills mode. If I use the 'Center Lock-On' autofocus it tracks (poorly) until I press the shutter button (when again it locks focus and stops tracking), whereas it tracks really well in still mode with the shutter half pressed.
Is this right? Am I missing something in the settings? Should I be using 'Center Lock-On' without pressing the shutter button to autofocus in video? Should I just give up with autofocus in video altogether?
Any help/opinions would be appreciated.
