That has to be the dumbest "proof" ever.
You are totally mixing up the ability to blur white and black bands, thereby creating grey, with lack of contrast, this is a spurious argument. That the Canon lens blurs the black and white bars faster than the others proves it has smoother out of focus blur. The fact that the dog picture didn't contain any black pixels whatsoever even though it has a black nose is a processing issue not proof that the lens has no contrast.
To prove your idea you'd have to show that a correctly exposed full spectrum image with areas in the background that are, 1, black, 2, out of focus, 3, large enough to not be affected by the range of tones around them.
Your Bridget's dog image would have been a good example, had it not been for the fact that the black levels were raised to the level that they were no longer black, or even close to it. It isn't difficult to prove there is no black after you take it all out.
A few years ago I worked making content and creating characters for video games. I'm responsible for implementing the first bokeh effects into a best selling video game. I'm personally responsible for creating some of the most iconic CG images of the last decade, and in doing so I consulted a few people on bokeh which consisted of dozens of optics experts that researched for universities. I'm certainly glad you set the record straight. For years, I've been foolish enough to believe that Ivy League professors were legitimate and knew what they were talking about.
There is no such thing as "blurring faster" when comparing identical apertures and focal lengths. The diameter of the circle of confusion is identical, and your statement is mathematically impossible. The Canon adds glow to objects that are out of focus. This is a very simple concept to understand and is not debatable.
You can decide if you like this glow or if you do not like this glow personally. However I can tell you that it is an unusual feature. Basically all of the common pro Canon, Nikon or third party lenses do not exhibit this behavior.
Hope that helps.
I believe you'll find that people will be more willing to hear your arguments if you state them from a more neutral point of view. Your initial post, though very thorough, was worded in a way that made you come across crass. It seems it put some readers on the defensive.
I personally disagree with you. From my experience, the Canon produces images that I like... at the very least, the IQ did not make me feel like vomiting!
I appreciate the experience all of the CanonRumors forum members bring to this forum and I do a lot of reading on here. That said, you shouldn't have to boast about your accomplishments or who your sources are to verify that your argument is valid. The argument itself should have its own validity. Again, not a very good move on your part to prove your point.
