Canon Lenses for Canon 350d?

[Michael Wyles]

Hi

I was just wondering if anyone can give me some advice? I have just bought the Canon 35Od and I am looking to mainly use it for shooting Formula One at Silverstone. I have been on to other sites and have had differing opinions as to which lens to get! I'm getting confused!

I want to stick with Canon lenses. Some people recommended the 200mm but others said there would not be enough reach. I got it down to two other lenses. The EF 75-300MM IS USM or the new EF 70-300MM DO IS USM. The second probably being the most expensive I can afford at the moment.

However someone has now advised me not to go for IS. Can you turn the IS off as he said it would interfere with panning shots. I have seen the 75-300mm without ISM but at a £150 this lens seems a bit too cheap. Obviously I want the best for the job!

Hope someone can help!
