I shoot on a pretty nice Nikon crop body, have a 24-70 2.8 and a 70-200 2.8, 50 1.4... and the wide angle I'm stuck with is a 6 year-old 18-135 3.5-5.6 I mean, this is a little ridiculous -- namely how lazy I've been about finding a good "middle ground" between a $2,000 Nikkor and a basically-worthless kit lens. I consider myself to be, at the very least, a decent semi-pro (or at least, I get paid like I am, for some reason), and I've just taken to renting a wide angle (and/or body) when I need it. But that's just not realistic all the time. And 18 mm on a crop body just ain't gonna cut it in this full frame world. Yes, yes, I'll save up, and I'll also do some independent research (Google is my friend). But I'd also really like some input as to a good, cheap, wide-angle lens for Nikon cameras. Can be prime, can be off-brand, whatever you think is good. Just not a fisheye. And, preferably, $500 or less.
