If by normal you mean about the same as Nikon I would agree with you. (why do I get the sneaky feeling you may not agree with me  ;D ;D ;D ;D)

I have to agree, from what I see published on some web sites testing these cameras, the SNR of all the top line cameras is pretty similar across their ISO range.

Well I didn't expect that!!!!  :-*

But I'll take the worse reported SNR of the D800 over the low ISO noise of any Canon product to date because it's less visible. MUCH less visible.  And any bloke with access to both cameras can determine that quite readily with little more than Photoshop and ACR (or Lightroom) and a lenscap.  ;)

Ahh that's more like it!   ;D ;D  Of course I could be countering with pointing out the 1Dx noise and DR at mid ISO's advantages, where I take most of my wildlife shots.

No offence intended  - From my point of view I think we are all really lucky that current cameras are so good! I did consider a change to Nikon for the low light performance and the 200-400 lens. I'm please I stuck with Canon as they have now caught up on the low light issue. I would love the new Canon lens with the built in converted, realistically I'm not going to spend that much.

Happy shooting.
If you debate with a fool onlookers can find it VERY difficult to tell the difference.

Meh. Unless this supposed 3D packs at least 47 megapixels, Canon shouldn't even bother with a high MP body.

While these are interesting, They don't showcase anything that couldn't be done on a d30. :P
HA!
Nice try. ;D

That's only +2 EV and 63% fill light on Adobe ACR 6.7
Either of those settings alone can show up banding noise in dark areas in some low ISO canon raw files. (I'm discovering there's sometimes more to it than that tho, can vary with Canon shutter speed)
Addenda: I can actually drag fill light to 100 to start to blow out the sand in the LR corner and it only shows a little chroma noise that could be removed with basic NR and still show plenty of detail.

I'd LOVE it if my 5D2 came out this clean at those settings.

check my tech blog for the dark noise comparison if you want to see impressive lens caps shots.

2 samples at ISO 3200 from D800 removed August 26th.

I think it would be named 1D S
There is the 1D X and 1D C  and then the 1D S ;)

Luckily there is no 1D S (nor 1Ds) yet, so there will be no confusion :-)

see below from the d800 for a sample of low DR scene that's NOT at base ISO:

- 1st is a 1/10th linear scale of the whole frame
- 2nd is a full crop

take a guess at the ISO

I'll provide a few clues:  f/8, 1/20s only a few points of luminance NR, May 25th, 7:50PM MST, in shade, about 53.5 degrees N latitude.  ACR 6.7 using 10 pts of luminance NR on top of the default 25 pts of chrominance NR.
Ancient 55mm macro for glass.

I'd LOVE it if my 5D2 came out this clean at those settings.

I really shouldn't clutter this particular thread with this so I'll likely delete this & other images Sunday
MEANWHILE:  did you guess iso 800?... nope
1600?...  not it either.
That's ISO 3200 performance on the d800.  Still pretty clean in the dark areas. and lots of crop-ability

Yep, I could do that shot w/ the D30, excluding the ISO 3200 and the 36MP.  8)
