Thanks for all your replies. I just think though, as has been said, that the lens is a little soft, after all it is just a kit lens.
Joe, I have checked the diopter adjuster and it seems fine, also I would like to carry on using manual focusing, so to just use auto will not help, in the long term (if that's what you are meaning?). My partner is currently looking at a couple of lenses for me, on ebay though, so hopefully I should have at least one better focusing soon!
