Well, wit my little experience I should say that there is correlation between MTF10 MTF40/50/60s and glare.



1. Tokinna 100 macro comes in my mind. Razor sharp test charts pure contrast. Real life experience - glare as an hell.

2. at [url="http://www.zeiss.de/C12567A8003B8B6F/EmbedTitelIntern/CLN_30_MTF_en/$File/CLN_MTF_Kurven_EN.pdf"]http://www.zeiss.de/...F_Kurven_EN.pdf[/url]

Page 17 Mr. Nasse is gives also an example of glare and relation between MTF10 and MTF20s and 40s. BTW at the same page Mr. Nasse is bashing all measurements based on single point MTF e.g MTF50

Of course, MTF50 doesn't tell the whole story. We could provide MTF20 out of the box. However, frankly, at some stage we've reached information overload.
