I have a Canon T2i that I bought over a year ago, and I absolutely love it. Currently, I have the stock 18-55 lens, and I bought a "nifty fifty" 50mm fixed lens from Canon. I use the 18-55 most the time, but the 50mm comes in handy. I want to step my game up and turn this into an active hobby, as I realize how much I love photography. I'd like some advice on lenses, attachments, and other accessories that can help me achieve my goal. I would like to shoot in these categories: -Ocean Photography: Surfers, waves, etc. -Macro: Fun closeups of interesting things for artistic photos. -Landscapes: I hike/camp a lot, and would love a lensthat takes great landscape photos. I look forward to your input, thanks!
