| p.1 #20 · 50 MP vs 50P focus rolloff difference |
I accidentally had #33 and 34 in view in stead of #32 and 33. They look very similar in most aspects (P at 4, MP at 2.8).
Have a look or two at Nasseīs paper Depth of Field and Bokeh, perhaps p35 and forward. My guess: The P has under corrected SPA, the MP (almost?) corrected, or at least far less SPA. That would affect the lightness distribution on the OOF point spreads in significantly different ways. Although we seldom look at the quality of closer than sharp field bokeh, this might add some insight into the matter on differences between the P and the MP. My prediction is that the P should have uglier close up bokeh than the MP.
