7d vs 1d3

I have been shooting quite a bit of sports lately and have been contemplating a body specific for this. What is the general concensus about the AF system of the 7d vs the 1d3 when it comes to shooting sports?

Thanks in advance, Friz

I moved from a 7D to a 1d3 and my keeper rate went up significantly immediately. YMMV...

That's just what I was was wanting to know. The 7D and the 1D3 are coming together in price and going pro in this regard is not much more expensive.

Thanks,

Going pro has nothing to do with the body you are using.

Sorry, didn't mean to ruffle any feathers. Some consider the 1D series to be the "pro" line. I know that the rest of the EOS line up is very good and can be used to make a living. My current line up is a 5D2 and a T2i. I consider the results from both of these bodies worthy of compensation.

BTW is there a measureable difference in noise at high ISO that I should be worried about?

I sold my 7D to upgrade to 1D MkIII. I shoot mainly birds and i found my keeper rate improves significantly. The 10fps is a great additional bonus too.

Set up the 7D AF properly, and it will do great at sports. The 1D3 and 7D are pretty close in performance at ISO 6400, with a slight edge going to the 1D3.

Thanks Speed,
I have been shooting sports with either the 5D2 or the T2i and my keeper rate isn't bad, but this weekend I was shooting an indoor swim meet with the 5D2 and was set up for a great picture. There had been a problem with the timing equipment and the water had gone perfectly calm giving a perfect reflection. I got a good one of the swimmer on the block, the dive, the splash and was going for the first stroke, butterfly arms extended. Timed it perfectly. Missed the focus. I think I was struggling between keeping the composition and keeping the focus point on the swimmer. Now one thing I would miss is the full frame with 70-200 in the cramped confines of an indoor event. The range of field of view seems just about right. Oh well can have it all. Well I guess I could if I wanted to spend 3500.

What do you suggest for a setup for the AF? I'm interested in hearing what works for you. My 7D seems weird and I don't trust it.

also dont forget that with a 7d you SHOULD have better cropping ability.

for 7d AF my friends use af point expansion, and adjust the sensitivity of the AF speed according to what they are shooting.

That is what I used as well for basketball and softball.
