So, I'd suggest that you simply don't answer at all. I'd suggest the same to TrumpetPower. The issues are important to some people here, but the repeated arguing is really damn pointless. Neither of you will convince the other, just accept it and move on. </rant>
That is good advice all around.
I think that too often people are compelled to post
something in response to a post, even if it's not contributing to the actual technical aspect.
If your momma never told you, "If you don't have something nice to say, don't say anything at all." ..
Well, here it is.
Amending it for an internet based discussion forum would likely go something more like,
"If you can't contribute something useful to the topic, please reconsider posting anything at all."
I have to commend all involved that, at least from what I've seen recently, the level of rancour amongst differing viewpoints has taken a more civil route, even on this topic which has been beaten to death since I joined up a year ago to discuss this very issue.
So thank-you, various posters, for doing your best to remain civil. It improves what is already one of the better places for photographic discourse.
Now for the tech contribution to the topic: I think we'll find that, as Canon moves into DiGiC 5 products, we'll see somewhat less of the general noise and banding issues which plagued a few of the DiGiC 4 equipped models and may have been less of a problem with earlier DiGiC 2 & 3 bodies.
A recent chat with a Canon rep, busy as ever manning a booth, solo in front of a large crowd of curious onlookers, who said that there are many
improvements in DiGiC 5 for high AND low ISO noise issues... A point he was eager to make when I told him that I'd dumped all my DiGiC 4 bodies due to poor noise performance for my uses.
He then handed me a 6D and asked me to play with it a while and let him know what i thought of it compared to the 5D2 I had... I know he already knew the answer to that.

Gotta say, other than the reduced overall noise and noticeably reduced FPN on the
6D, the thing I really like about it is the smoother quieter shutter. The 5D2 had such a crude THWACK! along with significant body shake induced by that big mirror being let loose and poorly damped. The 6D feels more like a nicely balanced match-rifle than the shotgun-like 5D2. it's even nicer, i think, than the quick CRUNCH sound the D800's shutter makes.
I haven't had a chance to
really shoot with a 6D, likely won't unless I buy one. Likely won't do that either until I find a compelling enough reason to go back to Canon for FF. And about the only reason that will be is if my hankering for a tilt-shift 24mm is not satisfied by the upcoming Samyang for F-mount.
Plunking a 6D on the back of Canon's fabulous 24 and 17mm TS lenses will likely be the most practical solution for some of what I want those lenses for. This might have been speeded up, somewhat, if the darn resale value for D800s was better. All those factory refurbs have dropped my resale value to the point where I now will likely have to keep using both of them for at least a year to get more value from them.
