Hey guys i really need help choosing a wide angle for my Nikon D80. Brand wise i"m not really that picky. From nikon, to tamron, to sigma, i don't really mind what brand, just help me get my money's worth. I'm not looking to spend more than 1,500 or so on some new glass but around that price range is absolutely fine. I'll be shooting city life and sports more often with the lens you ladies and gents recommend. Please help! Thanks in advance.
