I'm shooting with a Canon 50D and my primary lens is the 17-55 f2.8 IS. I love it but need something with a little more reach. I'll be shooting indoor and outdoor sporting events (some with low light), landscape, and some wildlife. I can't spend over $2,000. The 70-200 f2.8 IS seems to fit my criteria. Your thoughts?


If I'm shooting daylight landscape and wildlife, I'd like to add an extender. Comments or suggestions about the 1.4x or 2.0x?
