Would someone mind rating these cameras on ISO performance?

Just curious, I have only experienced the 5d2 and 7d from the following:

7D, 5D2, 1D3, 1Ds3, 1D4

From what I have read,

1d4 > 1Ds3 > 5d2 > 1d3 = 7d

Does this seem about right?

I've used the last three...
1d4 > 1ds3 = 5d2 > 1d3 >= 7d

5d2 is the only camera in this set that suffers from high iso banding
7d and 1d3 are very similar but the 7d is unforgiving of exposure error (although it has a better jpeg engine)

More like 1DIV>1DsIII=5DII>1DIII>>7D

Wait what?

What makes the 1D3 ">>" 7D?

1DIV > 5d II > 1D III > 1Ds III => 7D

Physics, for one.

Lack of banding, lack of significant noise at sub 800 ISOs, much better resistance to minor exposure error, superior color performance at high-ISO, a much larger sensor allowing for more overall photons.

There isn't a huge difference between all of these, no more than 1.5 stops. And there is no banding on the 7D unless you underexpose by 2 stops or more, and that would be pretty silly to do that.

After having used multiples of these (other than the 1Ds3), this is about what I have seen.

1D4 -> (1/3 stop) -> 1Ds3 = 5D2 -> (3/4 stop) -> 1D3 -> (1/3 stop) -> 7D

Yeah, but since when does hands-on experience and properly performed testing with actual cameras trump internet rumor and anecdotes from people who've never even held some of those camera bodies?

lol, it is just an opinion, hopefully it is accurate and matches what others found!

I did correct it above, I meant to put 1/3 between the 1D3 and 7D.

Hey TS, sort of off topic, but I see you own a 1d4 -- I seem to remember reading a lot of reviews of the 7D from you, why the switch? Are you happy with it? Contemplating doing it myself when the 1Dx comes out, but I would have to replace some lenses.

I'll have my 1D III and access to a 7D shortly - i'm curious for myself. My 1D III is being sent in for repair and I'll be using the 7D for some "club" stuff and then for rollerderby in a poorly lit "arena" - should be interesting to compare.

Especially when they are experts.

I don't know why people are rating the 1DsIII over the 1DIII, the 1DIII was intended as and is the better action and lowlight camera.

The 5DII is better than the 1DsIII at high ISO. The 1DsIII is better than the 5DII at low ISO. The 7D is as good as the 5D, which is weaker than the 1DsIII.

Not sure about the 1D's vs the 5DII.

Wow! Some of the responses are really whacky!

This post is the most accurate. From my own evaluation of the 1Ds III vs. 5D II, the 5D II has at most a 1/2 stop advantage. Not a big deal in my book.
