I'm sorry, but I don't understand the above. Because I've elicited
such (perplexing) rancor, maybe I should just rephrase the question.
If I were to choose, say, a Canon G11 (which allows shooting in RAW)
over a SX1 (which has the CMOS), would the problems that I have
articulated them that I have with reds/pinks/oranges--and that you
have articulated in a way I do not comprehend--be less likely to
happen? (I would purchase a green filter!)

The problem is that you have NOT described your problems with reds.
You've complained that oyu don't like the reds but without knowing
specifics it is almost impssoble to say what your problem might be.

Until you actually post a concrete *example* of the problem that you are
trying to describe it is completely impossible to answer your question.

A picture is worth a thousand words or more in a photography group.

You are not articulating anything that makes sense. Show us an image!

Clueless. Go and buy a Foveon sensor based camera that will have a red
photosensor for every pixel which may help. Or show us an image!

I don't know how to post a picture to a newsgroup. A Flicker account?

WOW!!! I never even heard of Sigma. I read a ton of reviews of a 14MP
camera, and most people seem to think it's the next best thing to
nylon stockings. This is indeed the issue I'm writing about--the
"aliasing" that I get from my Canons. If I buy a SX1, and I still get
the blotch, I'll lose my mind. The only question--I've only had Canons
(had a DLSR, sent it back). What's the deal with no auto-focus on the
cameras with Foveon sensors, and are there any competitors to Sigma
that have them? Leica? Thanks!!!

Find a hosting account.

Flickr would work, I use photobucket.

There are lots.

Register, read the instructions, follow the instructions,
upload your photograph(s).

Post a link to your photograph on the site
to this group, with your question(s).

It's possible that there may be issues with subsampling,
EXIT etc, but we'll cross those bridges when
we come to them,
