It is most noticeable in this image when viewed 1:1. One characteristic of the problem is that the dots appear always to the right of the highlight (unless shot vertical), strange. You can see it in this image if you view the full-size shot:

I also checked files from my 20D and don’t see the same behavior so from my perspective this is a new feature.

Sorry to here about Amazon. Try to give Profeel.com a call. They are very helpful in informing you when you might expect your product. I have canceled all my pre-orders and worked with Profeel. My order was placed on Wed, November 26 with Profeel. They called me to confirm my order and told me when to expect my tracking number. I receive my tracking number on Friday Dec. 5th. 5Dmk2 (body) will arrive this week. I did a check on the company via BBB, Reseller-rating, eOpinion, and consumer report which all had positive feedback. The only catch here is a deposit down. I actually paid-in-full to prevent any further delay. This is a local dealer in New York and it beat out (in my opinion) B&H (which I can’t even place an order), Adorama (list #923), OneCall (list #56), and Calumet (list #100+). Sorry I never buy from a product of this type from a non-photography retailer. Especially Amazon who uses 3rd Party retailers. Too many hands in the transaction results to an increase in transaction problems.

Best of luck. So you will have your 5Dmk2!

I will be ordering the 1ds Mk 4 which should reach my shop before the shipment of Canon 5d Mk2s that would have fulfilled my order.

- very small black pixels. Unlikely to be seen in anything other than very large prints. I did not let it stop me from buying the camera. CA is bigger problem with all but the best of lenses. In any event the black pixels are so repeatable that I am certain a fix will be available before long.

- I have not observed at 50 or 100 ISO.

- Seems to get worse with increasing ISO.

- Happens when you have saturated pixels followed by low light pixels left to right in landscape view. The black pixels are always to the right of bright light. This has lead people to think this is a sensor read problem.

- it seems to be worse at f4 than f8, but you can still see it.

In practical terms you will see this problem when you have a small bright light on a dark background. The worst I’ve seen are bright blue Christmas style lights against a dark background.

Now, what about that purple fringing…..

I just tested with 10x magnified LiveView, and it’s visible there within a certain exposure range, with a part of that range making it quite obvious.

It looks like a design flaw that affects all copies.

I had heard about the black dots but I bought anyway. Definitely can see them, but really, they are so small. You can barely see them at 100% and to be sure you have to use at least 200% or 300%. A quick photo of Christmas lights in the mall; not a complete test by any means, but I am pretty sure there will be some on the net before long. My intepretation of the problem is that a quick fix will be likely from Canon for the RAW files at least. A hardware fix may be longer in coming.

I got my auto-iso and I got my RAW in idiot mode (for when my wife takes my picture – ahem). I am a happy camper.

The IQ is outstanding.

Having said that I will be keeping an eye out for it. Hopefully it only effects a small number of cameras and is fixable! Interesting to see comments people have noticed it on the 1Ds mk3 as well. I have never heard of this complaint until last night, nor did I notice it during my short period of use of a 1Ds3 a couple of months ago.
