Anti-reflection coatings behave differently according to the incident angle. Wider apertures typically have incident angles that are further from the normal.

Also, wider apertures typically have light passing through the thinner parts of the elements, and so have less absorption, but I don’t think this is dominant.


Thanks Alan. But would this be this drastic? The jog is even milder, the ProPhoto version in a wide gamut monitor really shows very warm vs extremely cold.
