Re: Resolution versus detail......

Does aliasing play a role? Undoubtedly. But with the SD14 capture I
can absolutely determine that on the right side of the image there is
chain-link fencing. I would only know this from the 50D capture
because of a small amount of visible hint along the top of the chain
link frame. Likewise with the detail on the welded seam on the huge
wheel. It's hardly discernable in the 50D capture but rather obvious
in the SD14.

What utter nonsense. Seriously; with all the expertise that you claim to have, how you can look at the 50D image and NOT recognize that it either has heavy JPEG compression, and or noise or moire reduction applied without constraint?

Here's what the 50D looks like, out of DPP:

Now, which has both more resolution and detail?

"Resolution" and "detail" are just the metric abstraction and the practical consequence of the same underlying phenomena.

I suspect that the greater color resolution uniformity of the SD14
plays a role here and perhaps better dynamic range even thought the
50D has very good DR. The differences are quite apparent to me.
Better resolution from the 50D, more revealed detail from the SD14.
