Hey everyone, I've been in photography for a few months now, and I thoroughly enjoy it. I wish I had a bit more time to shoot, but eventually I will find/make time. Currently I am shooting with a Canon XSi, and the lenses I have is the 18-55mm kit lens, along with the 55-250mm IS telephoto lens. While I enjoy both of these lenses, I want something that will take my photography to the 'next' level in terms of image quality. Quite frankly I do not even really know where to begin in searching for said lens (as I don't know what I really want, or need). So I figured I'd ask the experts! What do I shoot? I shoot a wide array of things. Typically speaking, I do primarily landscape along with shots of people, with occasionally shooting at a sports game (not a big deal, at all). My price range Approximately $600-800. What am I really looking for? A lens that is pretty high quality (not necessarily L, as that is out of my price range), that will give me good image quality for years to come. I don't mind if it's a bigger (in size), but I'd rather not have another telephoto. I am not impartial to any brand (Canon, Sigma, etc). Also, I don't think it'd be the best idea, but how do you guys feels about buying two $400 lenses as opposed to one $800 one? Thanks so much guys, a wholly appreciate it!
