Hi


I recently acquired a Canon 10-18mm lens and used it for the first time today. Unfortunately the photos it is producing are quite awful. This could very well be user error, however there is always the possibility that it isn't as I have never experienced this issue with other lenses on the same camera body. I have included a sample image which has not undergone any post-processing apart from a conversation to JPG from CR2. As you can see from the images below the trees, leaves, etc. in the distance are not at all sharp, they look pixelated and smudgy (if that's a word) if anything.


Does anyone have any ideas?


Thanks
