Here's a low ISO shot with a highly-rated 70-200/2.8 lens on a camera with close to 14 stops of DR. By your criteria, it has excellent IQ.
Your criteria are just plain asinine.
I'm guessing here, but I think when he claims that focus has no bearing on image quality he is referring to the parameters that are not under user control. User can not remove noise or add DR to a sensor, but a user can change the focus. Just a guess.

As much as I enjoy exploring the latest from Neuro[resepct] and others on this site, I feel you guys need to take some chill pills ;D,it is after all only photography and not life saving surgery,just out of intensive care which gives a different perspective on things,keep on with entertaining us with your posts but possibly a little less rancour 8)

+1: It's not a lot of fun watching a pee contest that does not want to stop, people need to know when to take a back seat sometimes. People may disagree with Dilbert's position, his base observations that Canon need to improve one area is not without merit, it's when he gets too far and forgets the strengths of the Canon system that it starts to get a bit of a drab, granted, the fact that respected members of our forum try their best to shame him relentlessly, does not garner a positive response from him either, what surprises me is his resolve to stay civil despite all the hate directed. Guys, please lets take it a notch down so that the rest of us 500 odd people can enjoy discussing rumors!
And I humbly leave you all with this thought: In a pee contest, neither the loser, nor the winner come out clean...

Since we're talking about the elemnts that constitute a high IQ in a camera system, I wrote an article containing all the factors here: http://www.eoshd.com/comments/topic/7864-what-makes-a-high-quality-image-the-technical-aspect-of-image-quality-in-camera-systems/
A good IQ is npt just high Resolution, or just high DR, or just clean ISO performance, it's a combination of 7-8 elements to be considered.

Yes, you're 100% correct. Lenses have zero influence on IQ, AF has zero influence on IQ and all the other features of a camera such as metering, shutter lag and FPS don't cobtribute anything towards creating a better image. And, the only differentiator between the IQ of any film cameras was which film they were loaded with. :

Do keep that in mind the next time you go out to take pictures with nothing but a small, rectangular piece of silicon with a CMOS surface architecture. Be sure to show us the image quality of all the pictures you take, assuming you can find the shutter button on it.

Maximum IQ is (in a colloquial sense) a property of the sensor. Specifics of the maximum IQ of the sensor can be further quantified (I'll leave that explanation to those who know more about the tech than I). But the other components of the system also have their (colloquially speaking) maximum IQ as well.
IQ, i.e. "image quality" is...er...a quality of each individual image. An image that's unintentionally out of focus has low image quality to most people.
You must also remember that each sensor has different (colloquial) maximum IQ at each ISO setting. In effect, it can be considered a different sensor at each ISO. So even if you want to talk about the IQ of the sensor (as though it were an inherent quality) you must be specific about which ISO setting.

Therefore all images produced by the same sensor are equal in quality. Or, granting wiggle room for sensitivity: therefore all images produced using the same gain on the same sensor are equal in quality. Naturally, this also means that images produced without a sensor, e.g. by film, have no quality.
In reality, image quality is a subjective term. It is a property of the image viewed, and varies by viewer to viewer. There are certain objective measures of sensor performance, but none of them should be summarized as "image quality".

You sure? I've shot at ISOs less than 1 using these techniques. What sensor can I buy that can manage lower noise than my approach to get to ISO 1? Oh...my approach also allows you to dramatically exceed the resolution possible from atmospheric disturbance, and allows you to get to tiny fractions of a pixel worth of motion blur despite dozens of pixels of motion during the exposure.
Face it - IQ is about avoiding aberrations, and aberrations include noise, motion blur, out of focus blur, CA, flare, spherical aberration, and others, not just noise.

Some things are a matter of life and death.... others are even more important, like the never ending sensor debates. I need to know the answer! I need to know what sensor I should be using to take pictures of the cat to post on facebook... <SARCASM>
Seriously though, this is not a debate, it is people yelling and taunting and nobody listening. The truth is somewhere in the middle.

But make sure it lies still, so you can shoot multiple images and stitch ...neuroanatomist said:
