I'll take this one.  I feel that lenses should be tested at their
optimum image quality setting.  For the 85/2 and 100/2, this setting
is infinity.  For the 90/2 macro, it's 1:10 lifesize.

This way the great subplot about: who's sharper---the 90/2 or the
100/2 can be finally resolved to every one's satistfaction.
