As already hinted it is next in line ... and the MTF graph is weird (vignetting as well).
You may be aware that it is a T/5.6 @ f/2.8. Now I thought that the aperture is still the guiding aspect as far as diffraction is concerned. That seems to be -sort of- true for f/2.8 (T/5.6), also for f/4 (T/8). However, at f/11 (T/22) the data is way, way in diffraction land. Subjectively the figures resemble almost f/22 here. f/8 is a bit like f/13 or f/16. It seem as if diffraction "over-accelerates" the more you stop down.
The aperture ring does also range from T/5.6 to T/22 but not beyond.
Thoughts?
