At what point is the image corrected ?. I find the geometry on the jpg the same as the raw on this lens on a NX100.
Can i view it uncorrected ?.

Field curvature has nothing to do with auto-correction nor can it be corrected anyway - this is related to a curved focus field rather than a more or less flat one. The tested sample had a focus field where the border/corner focus was extremely pulled towards you so infinity focus (actually mid field focus) was lost.
I had to stop down to f/11 to achieve a decent corner sharpness. At f/5.6 even the mid field was already bad.
