Hopefelly soon, I can get a 10D. However, I'm worried about the AF speed of any teles I'm considering. I'm a fan of auto racing (drag racing), and having blazing fast AF is a MUST. Here are criteria and questions:
I'm looking for a tele between 200-300mm (before 1.6x conversion).
I must be priced less than 1,300US, so the 70-200IS 2.8 is out.
I don't care if it's a Sigma or Canon.
Questions:
Are there any teles in this range with AF as fast as a wide-angle lens (the wide-angle lens in reference to is the 28-135IS), or close to it, or am I kidding myself?
Is the F5.6 on most teles good enough at night if: there are floodlights overhead (so it's not in total darkess), and I'm using the 550ex with a shutter speed of 1/1000 or more and an ISO of 800? Or should I look at an F4 lens?
If I'm going to be using a monopod, is IS (Image stabilizer) really nessasary?
Please don't think I'm dumb, I'm new to this stuff!
