Tested SONY RX10 IV auto focus feature. Last week I did a similar test with full auto focus and found focus hunting problem. Some friends on Facebook suggested to use manual focus and RX10's focus hold feature. In this video I tried both and they both worked well.In this video, i have tested 4K format as well.Cheers!Last weeks video:https://youtu.be/ZHmQympUH8c
