Finally...

A few months back I picked up a Canon EF-S 10-22mm lens but then won the contest and purchased the Panasonic GF-1 right after. As a result I've kind of been neglecting getting out with the 10-22mm. For stock, I think it lends itself to outdoors since indoors you need a pretty clean room to use a 10mm lens without clutter :) Here is a recent shot that was accepted on Dreamstime:

On the technical side, I've found it to be very sharp and easy to use. It is fairly light and compact, and is still pretty wide when mounted on my GF-1 (20-44mm equivalent field of view). The CA is pretty low compared to other wide angles, but with a backlit tree you do get some. For a large print you probably wouldn't notice, but I still cleaned up the CA a little bit in Photoshop prior to submitted to Dreamstime.

The depth of field is amazing - this was shot at f/10 or so and the really close branches are only a few cms from the front of the lens! According to DOFMaster you get from 24cm to infinity when shooting at f/11!
