The EF 50mm 1.8 II What I like about it? The price. I want something better than the kit lens for indoors/low light, but don't want to break the bank. The other two 50mm's jump to 500, and then into the thousands, which isn't happening right now (at least not for that lens). Less than a hundred bucks is definitely do-able, but if it's going to be a big fat waste of money I don't want to be bothered, you know?
