Hey everyone, It's been ages since I've posted on here, but you guys are always so helpful and I appreciate ANY input. I tried searching back as not to repeat a previous thread, so sorry if this has been asked... I am looking for a wide WIDE angle lens that's no more than $500, some distortion is completely fine, and preferably an aperture that opens more than 4.5 (as I'll be shooting in low light situations without a flash at times...dragging the shutter). Is this possible? I shoot with a Nikon D200. I need it for exterior building shots (I freelance for a real estate company) and some fun, big, wide group/dancing shots at weddings (I freelance these as well) - just one lens for both of these! I just recently bought a Nikkor 20mm/2.8 on a whim because I had read great, great reviews about the "wide-angle" factor. However, I was so sad and disappointed when I got it in the mail today and it's no wider than my standard 18-70 that came with my camera! I should have researched more, I suppose. Any suggestions/links would be greatly appreciated! Thanks, guys.
