MTF (resolution)
#5
I would add that in my impression the third vertical section in the resolution bar, which was previously labelled "Good", actually stands for quite soft results. Perhaps not completely mushy - that's what "fair" (orange) and "poor" (red) areas are for - but definitely not really sharp either. Anything below "very good" is, well, not meeting the real standard of "good" at least for frame center, and there are rather few lenses tested with center performance to ever drop below "very good" (apart from very small apertures where most lenses are crushed by diffraction).
