Hi! Recent talk about 28/3.5 and 16-45 zoom performance got me confused.
My (probably very much Boris-the-average) belief was that most lenses are optimized at 3 or so stops from their widest aperture. So, for most f/2.8 lenses it would be f/8 or thereabouts. Is it right thing to assume? Or there is something quite basic that escapes me? Unconfuse me, will you please? :) -- Boris
