My favorite lens

I get asked a lot what my favorite lens is - well, it's the 70-200 2.8. I shoot with a Canon 5d Mark II and all my lenses are Canon. I have heard mixed things about off brand lenses. I figure if I'm going to spend that much on a lens I might as well make sure I'm getting the best.
I love the versatility of this lens as well as how sharp the images look. I can easily shoot an entire session with just this lens. My 2nd favorite lens is the 50 1.4. Some day I will get the 1.2. IF I ever come across an extra $1k.
Photography is one expensive art!
