I just sold some college textbooks, and I'm looking for advice of what to get with the money. I'd really like to get a long range zoom lens (300mm or so), but I don't think I'd want one with the little money I have, so I'm looking for advice on the basics I should be looking into like flashes, filters, tripods, batteries, etc... So far I have a Sony A200 with a Sony 18-55 lens, and a Minolta 50mm 1.7 prime. I have a good bag, a very cheap tripod, photoshop, and thats pretty much it. I have $160 to spend, so please give advice of what will help me out the most. I shoot everything from people to landscapes, indoor mostly though. Thanks!
