There have been lots of replies, including mine, but no one has
addressed a couple of general issues.
No manufacturer has always made only really great lenses. Even with the
finest makers, some lenses are better than others. Add in the length of
time over which major makers have been making lenses and the great
changes in optical technology over that time and the fact that most have
made various quality lines, and generalizations are meaningless.
Some Zuikos are better than some Nikkors and some Nikkors are better
than some Zuikos and the same goes for all the big SLR makers and the
major independent lens makers. It used to be that folks like Oly, Nik*n,
Pent*x, Min*lta, etc. only made first quality lenses. However, dealers
started pairing their consumer bodies with cheap 3rd party zooms in
price packages. Eventually, the majors mostly gave in. They figured if
people are going to use their fine camera bodies with crappy zooms, at
least they should make a little money off the deal.
Even in first primary lines, some lenses are much better than others.
The earliest of the several versions of the Nikkor short Nikkor zoom,
was pretty dreadful. Oly never really went far in this direction. Even
their "S" Zuiko zooms, the consumer line aren't bad lenses and a couple
are very good, like the 35-70/3.5-4.5.
I don't know about the various lines of all makers, but for Tamron, SP
is their top like, for Tokina it's AT-X, for Can*n, it's L, and so on.
So it is possible to get a poor lens from almost anybody and all the
major names have made at least a few great lenses. I wish there were one
central source of performance info for all lenses, but there isn't.
photodo.com <http://photodo.com/nav/prodindex.html> is some help, but
also sort of frustrating. We zuikoholics are specially blessed by the
amazing array of tests Gary Reese did for us
