For pure resolution this lens can\'t be beaten at this focal length for a start. The focus is quick, I have no problems with dust, to my knowledge, and I only use a 7-day-shop lens cap for any protection. I tried a decent UV filter, wasn\'t happy with the results (Hoya HMC). The colours are good and it works, in general, an absolute storm on the 40D.
Here is a sample shot only sharpened with default RAW setting - 3 - in DPP - flickr.com
And a 100% crop from the centre if you don\'t want to download the 10MP file.
For landscapes only this would not be a good lens. This lens actually is the man though for general purpose, lowlight, special effects - IS comes in handy there), DoF with portraits on crop.
If landscapes only is your thing I would really recommend the Sigma 10-20 - I have one - and boy does it stack up well to my 17-55 IS and 70-200 2.8L IS
A sample from the Sigma attached to a 30D -
And a 100% crop bien sur -
Hope my £0.02 helped.
