Hi Paul (sut68)
My trip to Durdle Door was actually the first time that I had used the lens, so I haven't had much experience of it as yet. My first impressions are quite good, though - it seemed to focus quite quickly and quietly and the selected point of focus produced very sharp results. My only disappointment was the level of distortion/lack of focus at the periphery of the image. For example in this image my focal point was the arch of durdle door (f16 @11mm) and I was quite disappointed by the amount of foreground distortion in the pebbles and lack of focus in the left hand edge of the image. I am not sure how much of this is acceptable from a wide angle lens - as I don't have much experience with them. With the lens I was using before (kit 18-55mm) I struggled to get anything truly sharp (even with a tripod in bright light conditions etc), so this lens is a significant improvement on this. (I see that you use this lens and don't seem to have that problem, so maybe it's just me!)
Sorry I can't offer more advice about the lens. I, personally, went for the Sigma rather than the Canon based on what I had read for example and the fact that I couldn't justify the price difference to my bank balance.
Hope this helps.

Kris,
That was very helpful thanks. I think I will take my Camera body in to the local camera shop and give it a try myself and see how much distortion there is - before I buy it.
In my opinion [and it's as brief as yours] the image should be pin sharp throughout, more so than the edges of your example.
Once again, thanks for taking the time to respond.
