A quick tour of the user guide for the lens doesn't mention it and I can't find anything in the R5's guides about it either. When I attach the lens, the corners of a square is centered on the screen about 3/4's the full height of the screen. What is it trying to tell me? The only guess I have is that is the available focusing area.

Correct.

Using RF800/f11, this is the size of focusing area with various cameras...

HxW:

R5/R6: 40% x 60%
R7/R10: 60% x 80%
R3: 80% x 80%
R6II: 80% x 80%
