It is a very good review. I do not understand why some reviewers see the noise and others do not see it.

probably a combination of:

1. some people can\'t tell VHS from blu-ray

2. some are using ACR 5.5 and some AR 5.6RC or C1v5 (ACR 5.5 will make a noisy artifacted mess out of any 7D copy)

3. some are using DPP with a more \'tame\' copy of the 7D and some are using DPP with a more \'out there\' copy of the 7D (DPP will make a semi-mess to varying degrees from somewhat obnoxious to not much of a problem depending upon which copy of the 7D you toss at it)

4. some people are comparing 7D to like an 8-10MP cam, both at 100% view


I haven\'t actually tested yet whether ACR 5.6RC and such just get rid of artifacts or reduce noise too, I would think they would reduce the artifacting noise if they get rid of the artifacts though and at quick glance I think it is ok, but haven\'t looked into it at all yet. I thought a few claimed it still seemed noisier even with new software and normalization at lower and mid-ISO, not sure, someone else claimed it was now great there. Unless maybe the column to column stuff still leads the converters to make a bit extra noise if not mazing.

Someone suggested it might apply varying degrees of compensation depending upon the individual copy, getting rid of artifacts in all cases but losing a trace more detail from some copies. Someone else claimed it sets the same compensation number for all bodies.
