Is it only at really high ISO?

What do people expect? A night shot is partly composed of black dots. At least to me this looks natural, just hit autolevels and it will look fine. There are also red pixels, just in case somebody wants to make another thread...

That's really bad.

Has this black dot issue been created on daylight shots with blown highlights?

Here's a photo I took where the highlights were blown on the water reflections. This is a full size image from the 5D2 at ISO3200, 1/125 f/3.5. Processed through lightroom (CR2 -> DNG). No black dots here.

If it's only at ISO >3200 for blown highlights at high contrast points in night cityscapes, that might not be as big a deal. What can you expect at H1 or H2?
To echo Ward's question above: Can anyone confirm what ISO was used for the photo posted by Caleb above?

Any estimate on the actual number of people who have observed this with THEIR 5DII bodies?

I propose a "Chicken Little" forum where threads like this can go until the "issues" they refer to are confirmed, in some objective and convincing manner, to be real and widespread.

I called it a few days ago. The sky is falling.

In all seriousness, are these "black dots" visible in any photos that are actually worth looking at?

Is it really necessary to call Canon management idiots. So they didn't catch this, big deal. Its a new camera and these types of things will show up and will be corrected in firmware.

Yes but seriously, this reflects quite poorly on Canon's testing and QC procedures... let's say they fix this- what's next, that they haven't discovered?

Stay tuned. I'm sure we'll find out soon enough.

Maybe if you are a brick-layer and like to admire your work, especially in dim, poorly lit conditions.

So please let me understand. We are going to begin a panic over the inability of the camera to handle terribly blown unusable photos when shots anywhere close to normal exposure are perfect. I agree with Mattbn and Monochrome, truly laughable. As I recall there was a similar panic on DPR with Nikon when they annouced their new cameras.

Actually I thought it was a horrible, over-exposed, noisy .... and completely flat image. However, the black dots added a bit of contrast and interest .... and somewhat saved the image.

Word on the street is that if you actually connect the black dots on these blown out shots, it actually spells out "Learn how to use your camera."

Why don't you go outside and take a 2 minute shot directly into the sun. Your next photo will have 21.1MP black dots, problem solved.

God damn .... the 5D II must be the worst DSLR in history .... it's terribly over-exposed and noisy as hell. I think you should return it for those reasons. Either that or we should start a thread on "How Not to Take a Picture".

On the lower left side is where I looked. Could be else where too.

Almost looks like the same places where CA would show up.

It appears, from other forums I have read, that several folks have found this same problem with their 1DSmkIII as well
