5dmkii vs 7d

Im looking into shooting a basketball game. Gym is OK lit, I have the 5dmkii and 7d. I see alot of ppl use either the 50 1.4 85 1.8 or the 70-200 2.8 IS, I have all 3 of those lenses. So just seeing which would be best? I figured the 7d for the higher frame rates and better AF but then the mkii is better at higher ISO.

7D for the better auto focus capabilities... a lower noise out of focus shot is worthless.

Take your 7D for 85mm and 5D for 70-200mm.
You will love the result and also don't have to switch the lens/battery/memory often,

Definitely with the rest on the 7D. The 5DMII is useable as a sports camera, and performs wonderfully in low light, but compared to something like the 7D (or even my 40D), there's noticable shutter lag, the limited fps hurts, and as others have stated, the autofocus is going to be quicker and more accurate with the 7D.

I also agree with Samsen (partially) on taking both bodies. Personally, though, I'd put the 50mm lens on the 5D and the 70-200 on the 7D. Most of your shots will be with the 70-200, so you'll want that on your primary body (the crop sensor will also give you a little more reach). You'll also want the versatility of the zoom. When I shoot sports, the longest lens is always on my 40D (generally a 300 or 70-200) and the 5DMII gets the wider angle (usually a 24-70 or 70-200). In your case, the 50mm will work well for shots under the basket (if you'll have access to that location), close in shots (assuming you're going to be near the sideline), or if anything else arises that calls for something wider angle.

Awesome thx guys maybe ill do the 70-200 on the 7d and maybe my 28-75 on the mkii for some wide shots. Then just bounce between that and the 50mm.

I had a 7D and tried it for basketball.
I hate to say this.......it was the worse for me. The noise level on it was bad.
I may have gotten a bad copy??
I was using it along a 1d MK3.

If you can bring all the lenses.
The 70-200 will have the fastest focus and will be the sharpest.

If you are going to strobe the arena, use the 5D2. If you are going to just rip images, use the 7D.

I use both. Either a Sigma 85mm or Canon 135L on the 7D and a Sigma 35mm for under the basket.

5D/35mm

5D Mark II for the full frame on a 70-200 f2.8 and with the 7D a 24-70.
