I'm about to order the Letus Extreme to use with my EX1 and am starting from scratch with lenses. I'd love some advice on one or two primes to start with. I will be shooting mostly interviews and interior narrative pieces--will usually be lit, so I don't need the absolutely fastest lens. I often need to shoot in confined spaces, so a somewhat wide angle is preferred. I'd like to keep my budget at around $800 total, for either one great lens or two good ones. I think I've decided on the improved Nikon AI mount (feel free to challenge this though) and am looking at these at B&H. They're all new--I'm open to used but don't see much right now at B&H. I'd prefer not to spend a lot of time on eBay, but if someone wants to suggest lenses to look for there, that would be helpful too.
