Autofocus item in display. Not sure what it is - R50

[Pauly_6_String]

Hello all. I have a new R50 that has a box come on the display that I can’t find much guidance about.

Pics included. It’s the larger box in the pics or at times just a box of differing shapes that appears and is NOT the autofocus area I’ve selected.

It seems to be tracking something if I move to re-frame. Is this Whole Area Autofocus?

Thanks

Thanks for the replies. I just came across them and haven’t read them all in detail. 

but I’m talking about the larger white/green box that moves. The smaller box is the 1 point AF mode. 

A check in the manual found that maybe this is related to “Detect”. It shows up if I have any detect mode selected. People, Animal, Auto etc. AF1 Menu on R50

I’ll look over the replies in a bit

Thanks again
