Well, I hate to hyjack the thread...but...I am thinking long and hard about picking up this lens. I'm new to this, so please be patient. I plan to shoot a lot at my kids hockey games, along with some tennis and football. After a lot of researching (trolling here) I am fairly certain that I would like/need a 70-200 2.8. So it comes down to the Sigma and the Canon L.
There is a farly big price diffrence. Other than the really cool white color, is there a big diffrence between the two optically? In the end, the price diffrence is a rounding error, but money is money.
This is one of those battles between the head and the heart. The brain says the Sigma offers everything I need and more. The heart says "yea, but look how cool that one looks". I have read a few posts and it sounds like some people are having a difficult time adjusting to the Sigma. I would have no idea why, so I'm asking for a little advise from you guys.
thanks, hyjack off.
