Default Which long telephoto lens for Cannon 10D

Iam only just learning about photography really but wanted a good enough camera to record and capture my youngest son who is roadracing on a Honda i bought the 10D and purchased the Sigma 17-35 lens to start with but now need advice on which long telephoto lens to get (i have been looking at the Sigma 50--500)or the Cannon 75-300is usm lens, is the Sigma worth the extra 300 or is there a better alternative .Remembering we can only get so close to the tracks.

Things to consider.

Can you use a tripod? Can you even use a monopod? The 50-500 is large and very hard (if impossible) to hand hold. Don't know about the 75-300.

Will the lighting be good?

At 500mm, the Sigma 50-500 is (technically) out of spec for AF on the 10D. The lens lies (reports its f5.6 to the camera) and it works... but in lower light situations it will hunt more than is probably acceptable (i.e. you'll miss the shot.)

But optically I've heard quite good things about the lens.

I know little about the 75-300.

Oh. Another thing. The 50-500 is hard to find in stock. Its been selling well recently.

The Canon 75-300 4-5.6 IS lens is a moderate lens. It produces fairly sharp shots at the lower ends but tends to be a bit soft at the 200-300 range. If sufficient lighting permits f8 or f11, you should get respectable shots.

Hey, I didn't say it couldn't be done. But most people can't do it (and wouldn't want to.)

I can't either especially when extended... My Santa just dropped one off

... notice those flying shots in the above link? they were shot @ >1/2000-3000s (& the EXIF did say f/5.6 @ 500mm !)

Have fun with the new lens. I'm holding out for the 300-800 I think. I already have 100-400, so I don't think another 100MM is enough of a gain to make it worth it (unless I replaced one with the other.) Of course, the cost difference is huge, so I'm rushing out to get it any time soon.

BTW, the EXIF data lies. The lens is f6.3 at the long end (as sigma says it is in the manual.) But it lies to the camera so it can still AF. Just like you can tape the first 3 pins on the Canon TC and the camera will still try to AF (it won't do it well, but it will try.)

Actually it's 160mm with the 1.6x... and I had a hard time deciding over the 80-400mm F4.5-5.6 EX OS which has no track record or availability (I might as well go for your 100-400L then)!
