Funnily I consider the center to be pretty useless (when was the last time when a lens was really bad or just good in the center?) but I'm loving my corners. ;-)

We are all different I guess.

 

@ Brightcolors - yes, this last mm of sensor space is a bit of an issue because this is where everything amplifies. We have to have some space there though.

 

I can't recall the lat time I had a photo with a subject in the extreme corner.

Most of the subjects in my photos usually closer to being on or within the orange circle.  The green circle is important for some images.  The blue circle is 99% useless...most of it is not even within the frame.  

 

PZ tests do not include data for the useful orange zone and give great importance to the blue zone.
