Still doesn't explain why this only applies to this Sony lens. Even the old Sony 135mm f/2.8 T/4.5 didn't show that behavior (to this degree) - although to be fair - that was on 24mp and not on 42mp.

The Minolta 135mm f2.8 (T4.5) STF did not use the same apodization element, it did not have T5.6 but T4.5, and the element did not sit that far from the aperture?



And yes. sharpening skewing the MTF results a bit which has become more clear with the higher res. sensors also makes comparing results a bit difficult/pointless, in this case?
