An article in the Nov '04 Pop Photo verifies that the
performance gap between zooms and primes is ever
narrowing. Actually, in one set of tests the zoom out
performed the prime.
I was both pleased and disappointed in the case of the
Pentax lenses. I had been mulling the idea of
replacing an FA 28-70 f/2.8 (glorious optic-but heavy)
with an FA 24-90 f/3.5-4.5 (at 50mm) which was pitted
against a 50mm f/1.7 AF (FA, F?).
Think I'll hold off on the 24-90. It's only one SQF
test, but not good. The 50mm results, however, were
extremely good. In fact Pentax tests (both good and
bad) stood out in the series.
Another benign dilemma.
