I recently bought a like new 50D with 6K clicks. I'm currently in the marked for an upgrade.
I'm really struggling deciding if going Full Frame or buy the new Sigma 70-200 2.8. My images are decent with the 50D but I feel there's something missing here. I currently shoot with a 75-300 which I know if a crappy lens.
I can only get one of the two. I shoot portraits and drifting events. Any thoughts from my fellow photographers? 
Some of my photos with current equipment below...
