Re: vignetting

In your own little world you are calling Canon a monopoly. No one is forcing you to buy the lens. Bottom line is Canon is a business, and if they can charge a premium for a lens that the competition does not have, more power to them. If price is a concern buy the Tamron or Sigma 18-50/2.8. As far as the movie analogy, want your own popcorn, wait until it is available to rent or purchase the movie, then you can eat your own popcorn to your heart's content. IMO, IS is over rated. I have three lenses with IS and I never use it.

It's locally monopolistic--no one else offers a wide-to-portrait
with IS. It's like the movie theatre popcorns, which aren't the
only popcorn solutions in town (= Nikon & Pentax), but they are if
you want to watch movies in that theatre (= Canon user).
Monopolies are not bad things, and I don't blame Canon for
innovating and offering something unique. I'm just saying that
their pricing practice is also in line with the fact that they have
something their competition doesn't, and that price premium is
often disproportionate to the feature delta. Returning yet again
to the popcorn analogy, when I was in college, there was a movie
theatre in the area with very tasty butter on their popcorn (=
17-55 IS), so people actually went there just to buy the popcorn,
despite having to pay movie popcorn prices for it instead of buying
grocery store microwave popcorn for cheaper (= Sigma, Tamron,

In any case, as we all learned in economics 101, value/utility is
an awful tricky thing to compute, since it's often subjective and
personal. So I'm not trying to tell anyone that 17-55 is worth it
or not worth it, because that's going to boil down to each
individual user. $1100 might mean peanuts if you're wealthy, or if
you recoup that cost by selling your photos, or if you're getting
rid of a bunch of other lenses on eBay to fund the purchase. But
it might mean a lot if you're a student, or if you're married and
your wife nearly divorced you for your last spending spree, or if
your bank account is close to flatlining. I'm merely presenting
some thoughts I had while evaluating this lens, in case others
might find the information useful.
