Hello. I would like to purchase new or used a wide angle lens for large wedding parties. I have a Nikon D200. I assume I would need a fast lens, minimal distortion which may not be possible in a wide angle lens. I need to purchase ASAP.. I have another free wedding end of July. This year I am not charging. Next year I'll start. I have told people to hire a PRO. They cant afford it.. I make them sign a contract saying i advised them to hire a pro..
