Not B&W resolution charts.

Odd, but my B/W versions of my Sigma photos have the same detail as the color ones. How do you explain that?

What's odd is this statement is a non-sequitor -- it has nothing to do with the conditions where mosaic sensors can essentially hit maximum resolution.

It's fair to say that when the average consumer hears that a camera has more resolution they are also thinking about more detail.

For the types of shots they actually take.

LOL. What the heck do you think people are planning to do with their cameras?

Use them indoors and out, mostly for casual and candid photos of family and friends.

Well, there you go. Can you reconcile that with what you previous said, which for some reason you chose to edit out of the conversation?

Above is the full context. What's to reconcile? Consumers expect that "more detail" will apply to all of the photos they take, not just a few circumstances.

Then we don't need to keep it simple - there is no single number that will rank image quality. For similar systems, MP has a decent correlation with detail but that's it.

MP has no "decent correlation with detail." A 15MP Foveon image has far more detail than a 15MP Bayer image.

Sigh:

  1. You left out "for similar systems". X3-based cameras are not similar for most people.
  2. Even if you include X3 systems, those few outliers does not invalidate the correlation when it applies to the vast majority of data points.

Sigh. Do you even know anything about the cameras being discussed?

Where I joined the discussion was the statement "Is it fair to call a 15MP Bayer sensor camera 15MP when much of the color is interpolated?" Can I help it that you forgot what your were saying?

Sigh. The camera being discussed is only effective at ISO 100-400. Those ISOs are logically the only ones that can be compared.

What does that have to do with the "fairness" of MP counts? If we go back to the "average consumer" above, are they only interested in detail at ISO 100-400?

Above where?

Just a few lines up.

You are editing up the conversation so your previous comments can't be viewed.

Huh? They can be still be viewed - they are still in the thread just a click or two away.

Once again, I never said "MP is a measure of resolution." Read more carefully what I write.

Since you have such a short attention span, you wrote: "Is it fair to call a 15MP Bayer sensor camera 15MP when much of the color is interpolated?"  What did you mean by the second use of "15MP" if not resolution?  How carefully do I need to read this?

even though you are the one that brought up what the "average consumer" might think. "Those who care more" will arrange to shoot with the various cameras and make up their own minds and not depend on marketing claims from either side.

Now it's clear why you are editing out the previous conversation, so you can dishonestly misrepresent what I have said.

All of the previous postings are intact - if I were to misrepresent anything, editing would not help.
