Hi guys, sorry for another spec me thread. I find myself on the wide end of my kit lens a lot doing landscape shots, but it's just so soft at small apertures and on a crop body it is sometimes a bit limited. I'm not too fussed about huge apertures etc as I usually use a tripod, but I just want something sharper (and wider) that allows me to get enough dof without losing too much sharpness. The canon 10-22mm looks nice, but there are quite a few other lenses in this category and they seem to have pretty similar spec. What do you guys use?
