I really need a new lens for my 30D. Here is what i have -Canon 30D -28-135mm @ F/3.5 -70-200mm @ F/4L IS -insert something wider than 28mm here Now I played around with a buddies 17-40mm F/4L all day yesterday and was impressed, but I would like to go a little wider if i can keep a quality similar to 'L' glass. Any suggestions? *I have no problem putting out the money for 'L' priced glass...$600, $800, $1000...whatever, I just want excellent results. I think i would settle for a nice fisheye or semi-fisheye, but examples of images shot with the lenses you guys come up with would help.
