I think you've got the right sort of understanding. Canon
and Nikon, for example, are top line manufacturers. That
means that for lenses their quality control is rather good.
It does NOT mean that all of their lenses are super wonderful.
Some designs just don't cut it.
Other manufacturers, and Sigma is a very good example, also
have some good designs and some lousy designs. But they can
keep costs down by NOT controlling quality as tightly as
Nikon or Canon. So the sample to sample variation can
be larger with Sigma.
The best advice, I think is the following: Read reviews
and avoid what are generally thought to be dogs. If
you can afford it, stick to the top of the line manufacturers.
If you are like most of us and can't do that, then your
job is a bit harder. Find good designs (by reading reviews)
among the second line manufacturers and then try to buy
at a place that will do an exchange if you get a dog.
In the end, however, when it comes to buying anything,
it is more difficult to be poor than rich...
PS: I have, for example, the 12-24mm f/4 Tokina for my
Canon 300D. It is a wonderful lens (at least my sample)
and I love it. It won't cover a full frame camera, but
then I can't afford a full frame camera...
