Well, I started this discussion, and got a lot of good advice. I put together a spreadsheet with makes, models, specifications, sizes weights, dimensions, prices and sumarizations of reviews. Still did not come to a 100% firm conclusion but was, repeat, was, leaning towards the Cannon 16-55 Image stabilization lens for around $1,100 (which was too expensive hence the indecision). The reason to lean in that direction was general purpose all around use and for the image stabilization.
I BOUHT THE CANON 10-22 LENS. Why you might ask?
Because it is specialized for landscape, which is what I want to do more of.
Because it has low chromatic distortion and is very sharp within a fairly broad "sweet spot".
And finally, what put me "over the edge"?
Because I found a clean used one for $350 less than what a new one would cost and snapped up the bargain. Specifications, features, did not tip the decision. A good bargain on a plausible choice made the final decision for me.
Anyway, thats my story and I'm stickin to it <grin> The next challenge is to get familiar with the lens. It is VERY wide.
Nice sample shots with this lens from PBase are here (not my work)http://www.pbase.com/generepair/image/74954608
