Thanks to all those people who have offered advice to me in relation to my new Canon 20D and operation. As previously mentioned I purchased the 20D and Canon EF70-200mm f/2.8L IS USM for Aviation (Air Show) photography. I'm off to NAS Oceana in Sept from home here in Australia. I want to maximize my opportunity to photograph the "Tomcat" before its withdrawal from service. I found that at the NAS Oceana 2004 show my Nikon 70-200 mm was just a little short on "legs" even given the 1.6 digital factor.
I have also purchased a Canon EF 2 X II Extender with the Canon kit mentioned above. My query is will I lose image quality if I go for the 70-200mm f/2.8 and 2 X Extender over say lashing out and purchasing a EF 100-400mm f/4.5-5.6L IS USM. Which of the 2 scenarios will give me the best results given that I will be shooting some very fast military jets.
Thanks in advance to those who are going to offer advice

I do believe if you are going to get the 2x extender, I would stick to the 70-200 2.8. It's sharper, faster and you lose AF on the 100-400 with any TC on it I believe. It might lose AF only on certain bodies but if I remember, no matter the body, you lose AF on the 100-400 with any TC attached.

I don't think he's asking about using the extender with the 100-400, but rather which would be better?...70-200 & 2x OR 100-400. personally, i have the 70-200 with a 1.4x, and i'm likely going to pick up a 2x before oceana. of course, to maintain that L quality with the 2x on the 70-200, you will most likely need to stop it down to f9-11. when i have the 1.4x on i usually shoot in Av at f8. of course with the 20D, you can easily bump the iso up to 200 if you need to maintain a faster shutter speed (which, considering its oceana, you will need a fast shutter speed)
i would stick with the 70-200. that will be the set up i will be using at oceana in 2 months. plus, you will still have the 70-200 2.8 which would probably come in very handy at the night show
