Sorry if this was asked before, I didn't find the answer anywhere. I used to use Flex point AF-S only on A7. Now I am trying the AF tracking. When do AF tracking in A7, does it show a single frame in green or multiple little squares? I did google and strangely in GaryFong's video I saw some little squares like in A6000 tracking but on an A7 body. I use AF-C, wide focus area and lock on with shutter on my A7. With FE 55/1.8, it shows a single frame on the object and track it. Is that right? Where are those little squares? Also, if lock-on is set to "On" instead of "with shutter", there is no frame showing and pressing the center button pops up a message saying that the function is not available for AF-C, why is that, I don't understand. Please help. Thanks!
