$ I am now using the kit lens (EF-S 18-55 F 3.5-5.6) and am satisfied with
$the angle, but I am interested in a better quality picture.
If you needed to go wider than what the 18-55 provides, the
10-22 would be a fine choice. But if your need is for a similar
angle but better optics, the 10-22 isn't the right lens.
$ I am trying to find out
$if the quality of the 16-35 is that much better than the other two as the
$price might indicate.
That's not what the price indicates; the price indicates that it's
twice as fast (f/2.8 vs. f/4). There are a number of comparisons
of the 17-40 and the 16-35 on the Web; you can look for them for
more info. Most people who've used both conclude that they're
in the same ballpark, with each one being better than the other
in some ways (for instance, the Luminous Landscape test shows
the 17-40 is better at the wide end and the 16-35 is better at the
long end).
When I was preparing to move from film (with my widest lens
being 28mm) to digital (20D), I knew I'd need a wider lens to retain
the same field of view. I would have loved to have the 16-35 for
its extra stop, but there's no way I could justify the money. So
I got the 17-40. I am pleased with it. It's sharp. Not as
sharp as my 50/1.4, but let's be fair here; you can't expect an
ultrawide zoom to be as sharp as a normal prime. It's definitely
sharper than my 28-135, which is arguably Canon's best consumer-grade
zoom. Its mechanics and construction are what you'd expect from an L
lens.
