I was also wondering about that statement in the review. I suspect a
statement that performance started to fall off after f5.6 would be more
appropriate - and accurate.
The Tamron 90/2.8 in Pop Photo's test had an optimum aperture for macro
of - wait for it - f2.8, although performance was great down to f22. My
test of the later, Di version showed the same thing.
