But higher color resolution equals more resolution, resolution in terms of detail.

Completely wrong.

Humans can't see colour detail anywhere near as well as they can luminance detail.

You can blur the colour in an image by quite a bit before it becomes noticeable.

Then find me a 15MP Bayer sensor camera that can even come close to the 15MP Foveon.

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 luminance detail, not chroma.

The consumer simply expects to see more detail. I refer you also to my previous comment.

I refer you to any textbook on human vision.

Humans can't see chroma detail as well as luma detail. This is a fact.

You can pretend that's not the case, but you would be incorrect in doing so.

As I said, you can blur the colour (and by quite a bit too) before it's even noticeable.

After all, the implication is that a higher MP sum will yield a higher resolution photo than something less.

And for most cameras of a similar type in similar conditions this is approximately but not exactly true. But if you compare a cell phone to a DSLR in dim light it will not be true.

To make it easier for you to follow and not deviate, lets at least keep the sensors similar in size.

Then why do you keep comparing a DP camera to a Nikon D800?

Where am I doing that? As far as I recall someone else brought up the D800.

Here's one of many:

A Sigma DP series camera costs a fraction of the price of a D800e and delivers resolution, as per the Oxford definition provided, that is almost as good. That's what really bothers you, doesn't it? You showed that in the previous Sigma thread.

It's also not 'almost as good' by any rational comparison (i.e., objective measurements).

Put aside your irrelevant and silly personal bias against me and you'll be able to see that.

I have no personal bias against you or anyone else.

I do, however, have a problem with gushing fanboism, contradicting statements and factually incorrect information.

Since it is well known, even by the detractors and haters, that Sigma cameras are ISO 100-400 cameras it makes no sense for you to be talking about high ISO.

Yes it does, because that's what people want to use. High ISO opens up so many new opportunities, and they can still use lower ISOs if they want.

No, that's not what all "people want."

Did I say all people? No, I didn't.

Nevertheless, cameras with high ISO outsell Sigma, so obviously many people do want it.

Can a mosaic camera resolve 15MP of detail with the right target and algorithm? It seems that 15MP is a max theoretical resolution not a guarantee.

I have no idea what you are talking about and how that relates to anything I have said.

You have no idea what you're talking about, let alone anyone else.

Last time I checked, you are and "you're" are two forms of the same thing.

It's a good thing you checked. Now you know what a contraction is.
