Re: Noise and sharpening
Ive not noticed much noise if any until about iso 1250. The default software from canon (DPP) is pretty good at removing it using 3/3 on the settings. I don't mind putting a couple of raw files of random stuff up later if you want compare another 5d2. The noise definately doesnt show up in prints.
I don't doubt canon have pushed a wee bit to far with this sensor, although the pixel density is still relatively low compared to say the 50d. There is noise but comparing it to shots from a 20d and 10d shot at 400 iso and the 5d2 at 1250 and the 5d2 has less noise and removing it is more effective.
Perhaps sharing some examples might help?
BTW I dont wish to come across as a canon fan boy, I'm fairly independant of any one system right now, I just have experience of the 5d2 and by my standards the noise at sub 1600 iso is relatively low and doesnt tend to show up in prints until you go for > 16x24 inch prints. FWIW my experience has been that noise always looks far worse on screen then on paper and at large print sizes it adds some feel to the shot when it does appear in b&w shots.

I'll do you a straight swap.... If you're missing the old 5D.

Re: Noise and sharpening
I stuck up a shot with plenty of shadow area from a couple of weeks ago, I was testing exposures \ latitude at the time, from memory it will be low iso 100-200 and maybe .5 - 1 second in duration on a 5d2.
There is some patina in the darkest black area, which could be either noise or actualy texture from the shot. Please feel free to compare, my fine could be noisy as hell to you lol. Compared to film the 5d2 kicks out ultra clean images albeit at a much lower resolution.
5d2 raw
Hope it helps.
PS it wasn't meant to be a masterpiece! artistically it is a train wreck.

When are you seing the noise Simon. 100% view or at 50%? A lot of the noise we will see on screen at higher magnifications is not going to show on print. Maybe you could give us a 100% crop of a cloud and a shadow to look at. I have read a lot about this in forums, and it seems it is not a problem in print, more in pixal peeking on the screen.

Dave
Sorry Dave meant to reply then got distracted , then forgot!
here is a 100% crop
From this image:

I am curious to know whether tis would show ona print - I know Martin has talked a little about how to get over it but I have no experience to tell me how much shows in print
What I have here on this image is more banding than noise really. As you can see from above posts I asked about it on the adobe forums
Please let me know your thoughts?
thanks

Re: Noise and sharpening
Thats banding. What did the original look like out of camera?
What lens? Auto focus or manual? Do you now if the battery was low?

Re: Noise and sharpening
It depends how big you print, at 10X8inch on matt paper you should get away with it, any bigger and it will start to show worse upwards, if you printed on gloss paper it would show on even smaller than 10x8 inch. It really is a bad fault, hard to accept this for a supposedly semi pro camera costing over 2 grand 
Martin
One question, is this the result from opening dark areas on the image

Aperture priority, 17-40L, 1/80@f22, Auto focus most likely. Battery was fine
This jpg straight from LR with no adjustments at all
What are your thoughts guys? Is my camera crap or is it to be expected from such an exposure?

Re: Noise and sharpening
In photoshopt that area shows all 3 channels clipped, so it may be too much for that sensor. that said, Martin's MKIII from what I have seen would pull that cleanly. You may want to check with Canon and send it back. . I suppose also though, bracketing that shot would have been best as the histogram show both ends clipped.
You are not the first person I have seen with banding problems on the MKII. Another gent sold his 1DS MKIII to buy the 5D as it was toughted as the same sensor. Turns out that is not totaly true. I do not think Canon will ever give the same image quality of the 1D series cameras to the other levels. (time and technology of course will even things with older models, but that is not what we are talking about here).
As someone who is really thinking about the MKII, I am a little worried.
Noise is one thing to fix, banding is much harder to remove.
Jeff Ascough shoots weddings with 2 5d MKII's and couldn't be happier with them. He shoots available light (read low light) out of Lytham.
I guess I would talk to Canon, I don't think your camera is living up to their description of the camera. Just my .02

Dave
