Congrats on the new glass. Excellent choice. I admit, it's performance was somewhat lacking on the 300D, but since using it on my 20D and 30D, I can say with some certainty it wasnt the lens. The 300D is a nice kit don't get me wrong, but, the AF on the 20D and 30D is far superior. It's been spot-on with my new bodies. The only negative feelings I have toward the lens is the speed, but, a steady hand and IS help a lot.
Just a suggestion. Once you do sell your 70-300mm, you might want to put your $$ earned toward something a bit faster. Maybe pick up a Canon 200mm F/2.8 L! I say this not knowing what your kit looks like, of course maybe you are good to go already.

Quoting Aero145 (Reply 8): I can't wait to see how you are going to manage to use 100mm widest for approach shots of (for example) 747s on short final for runway 27L
Definately a down side, I use the Sigma EX 100-300 and although I love the lens 100mm is just too long quite often and my small lens is the 24-70 so I get frustrated by the 70-100mm gap I have personally, may get a 70-200 and 1.4x to replace my 100-300 for this very reason.

Quoting Linco22 (Reply 20): I'm interested to hear your indepth thought on the 2.8 24-70 Sigma you have...
Ian bought his off me so I can answer.
It is a superb lens, very bright and sharp. The focusing is a little noisy when you are used to USM but it is fast and precise.
So why did I get rid of it ?
The problem I found was that it was not wide enough when fitted to a camera with a 1.6 factor. If all you photograph is aviation then the 24mm end is likely to be fine, but I bought the Canon 17-40L which is a better walk around lens for me when I am doing my non-aviation.
I have to say that I cannot detect the slightest difference between the two lenses in sharpness.
