This is interesting. I had always thought that flare when shooting against
the light was an obvious, exagerrated symptom of flare in the lens overall.
Even in general shooting, therefore, I figured that such a lens would
suffer in contrast compared to one that did control the contre-jour flare.

Looked at another way--if a lens has coatings that allow it to control
flare in the extreme case (contre-jour), wouldn't that translate into
better contrast (or micro-contrast) in normal situations?
