The best iso

What do you think I have a 7d now and shoot low light sports.
I have a choice of the 5d II- not alot of focus spots, slow fps.
1d mark 3- 6400 max iso
1ds mark 2- max 3200 iso I think

Which of these would have decent iso compared to the 7d. I'm think the mark 3 because of the fps but I like the idea of a full frame

Mk III.

And APS-H is pretty good.

Mk III with that 70-200 is a killer combination.

yup...the 1D2 is really not all that great at high ISOs and the 5D2 is not really a sports camera, though I imagine it would still do well...but, for your purposes I think the 1D3 is the best of the batch

If you can not get the1D Mark IV
i say stay with your 7D and shoot (expose) to the right
(do show us some pics of the 7D that you are not happy with )
of course the 1D III is a great camera but for what you want i think you will get marginal improvement

Which means losing at least 1/3 stop shutter speed. If the OP is shooting low-light sports, that's not a good idea.

Might as well just get a camera that performs better than the 7D at higher ISO. The Mk III is one of those cameras.
