Let's say you were in the market for a new lens. You do mostly weddings and portraits with fine art and commerical work thrown in. You already have the standard kit lens and a 28-300 3.5-6.3 Sigma lens. What would you get next? Oh, and you have a Sony Alpha. I want something with 1.4 or 2.8/F at least. I don't want a major zoom (yet, the one I've been eyeing is $1500). What would you get? Price range is up to $300 unless I can get a couple more paying shoots or sell a couple prints.
