disappointing results at ISO 100:

banding:
horizontal banding appears to be entirely removed, this is good, and will help make ISO look better and get less badly clumped chroma noise and all but vertical banding appears to be zero improved and it shows up enough that I don't think you gain any usable amount of low ISO DR back compared to the 5D2

so for low ISO I'm not sure the removal of horizontal banding alone will really help usable DR any since the vertical sticks out to the eye just as much, maybe here on there on parts of the image it might help

DR:
5D2: 15760,1024,6.1 AU,3.8 8MP normalized ADU, DR - 11.2  , DR8MP - 11.9

5D3: 15309 (maybe the channels were still not quite blown though?),2048, 6.6 ADU, 6.4 normalized to 5D2 6.4 and then to 8MP 3.96, DR- 11.0  DRto5D2 - 11.0  DR8MP - 11.7
and let us say WP should be 15760 instead then DR8MP - 11.8
and let us even say it should be max 14bit 16383 - 11.8

so I actually get fractionally worse DR than for the 5D2, but it's for all intents, the exact same, within copy to copy variation and well within any difference you'd be able to notice

Sad to say but even the DX D7000 handily beats the latest Canon FF for DR, and not by a little. The D800, at 100% view, full 50% MP advantage may beat it by 2 stops, maybe even 2.5 usable stops.

I did not expect this at all.  :'(

(the high iso side of things should turn out more favorable though, most likely)

Thank you, @akiskev, for those sample videos! I'm really amazed at how much 10% luma and 30% chroma noise reduction cleaned the photo of your father right up. With my 7D, I often have to crank chroma noise reduction up a lot more than that at higher ISO's, and I usually apply about 25% luma noise reduction.

Akiskev,
Thanks for the video, I know it seems the 5D III is getting dragged thru the mud lately but I believe I’ll be pretty happy with it.

Thanks akiskev.  I looked at the videos you provided but not following exactly what/why you tweaked in ACR.  I use Aperture and PS but am an admitted novice at best.  Color balance, dodging, burning, cropping, and sharpening are easy enough.  But removing noise and cleaning up photos as you did in the videos is uncharted territory for me.   Any recommendations for tutorials?

I'm not sure yet but at quick peek it seems like it still uses the fake intermediate ISOs.
Someone said that real ISOs go higher than the prior ISO1600/3200 of other Canon models though.

Arghh!  :(

If D800's DR and S/N turn out to best the 5D3 at pixel or print levels I'm gonna be SO disappointed I recently spent a load on new Canon glass.

Thanks for your dogged analysis of the 5D3's files.  I'm hoping the production version of the thing shows more tangible improvements.

Try NIK at www.niksoftware.com . I was like you and I don't have time to learn CS5 and PS, so I "tried the trial" and got hooked: easy and effective enough. From Aperture it works quite easy as a plug in. The whole suite is at a good price at B&H.
Just as an idea.
There are plenty of other options too, but we are off-topic here.

Yes, I'd be turning into 5D2 territory slowly. Why spend the money for features I don't need. Let the pro-s use the 6 fps and the high ISO. I needed IQ improvements at base ISO, well, another 4 years of waiting. Probably not possible with the current sensor tech.

I use Topaz de-noise which works really well
it lets you apply different strength noise reduction to shadows and highlights as well as control
specific colour channel noise and has an option for pattern noise if you are pushing that far

the only issue i have is when i load it as a plugin to lightroom the colours go all crazy in the topaz editor
(doesnt affect the image though but its annoying i'm hoping lightroom 4 fixes this)

wickidW, do you think 5D2 will drop further in price when the 5d3 is in the shops? Now 1839 A$, I think I'll stop dreaming for the 4000+ 5D3, no point for me. This will be slowly the end of a dream.

$1839 is pretty cheap, where is selling it that cheap?

I cant see it getting that much cheaper since its not going out of production and
is going to be cemented as the entry level full frame. The fact is the 5D mk2 still
produces outstanding images this isnt going to change if you are budget concious that extra
$2000+ can sure buy alot of nice glass to go with the camera depending on what you already have

i was considering selling 1 5Dmk2 but the price drops make it pointless I'll just keep it going
(both me and my wife shoot so for weddings we need 4 cameras, just in case anyone thought i was an octopus to be able to use that many cameras at once :P
