Interested for your updates - i bought this lens also for canon over a year ago, but don't get to use it much. I had a quick look for flickr shots using it - none. so maybe its not that good for me either. The only one i found was this link=]Longleat on Zooomr [/link] or Longleat - ePhotoZine Version

Must have been a very quick look!

You may have a soft one, if its new and your not happy with it send it back. have you really tried to get to grips with it as it can take a bit of getting used to.

What format do you shoot in and do you process shots afterwards?
Do you do any sharpening after processing, necessary in most cases, particularly if you've been shooting in RAW.

With very wide angles, you need to be careful where you focus. There can be some distance between what is in the middle and edges of the frame, with close objects very close and out of DoF range.

Or save the 200 and buy something nice with it, quality is not very (if at all different).

ive had this lens for about a year, I love it, dont really get many problems with it as with any 10mm lens you will get the pin cushion effect and it may look a bit streched at the long edges. but not really too noticable unless your selling your images in poster format. sharpness is good, but stick to around f/11 to f/16 , should be sufficent for most stuff. also depends on the settings in your camera. for example, your style settings, its its set to standard then theres only a tiny big of sharpening going on in the camera. if you set it to faithfull or neutral then theres not camera sharpening at all, so setting the camera style to landscape while in AV mode should give you the sharpness back you come to expect, G

I've just had a look at the photo you've uploaded.....I don't know if it will be a good enough example to see any faults....can you take some with something foreground ...a rock/flower etc.

Try pinning up a text heavy newspaper page on the wall or lay flat on the floor. Align the camera so the ccd is parallel to paper and everything is squared up and take a photo. You can then check the centre and edges of the frame for sharpness of the text.

if you are going to use this lens focus about a foot in front of yourself at say f/8.0 . i bet you are focusing to far in front.
