We're at f/8 at a midrange focal distance (Dean headstone).
Septon is STILL fringing at f/8 in the corners. Nokton seems to have a deeper focal plane than the Ultron, which I found interesting (background leaves seem softer on the Ultron, even headstone slightly behind focal plane are softer). TTA and Nikon both performing just fine by f/8, though the TTA has a deeper focal plane than the Nikon (likely due to the wider FOV).

Scott, thanks for next examples. Nokton is my favorite so far. How far was Dean's headstone? Looks to me about 7m? I'm most looking forward to examples with the focus set on further distances - several dozen meters and before infinity at f8 - 11, for classic landscape shots. f
