Will the K-3 automagically kill purple fringing and the like?

Probably reading way more into the ability of the camera than is actually there, but from the description over on B&H's site, it describes the sensor as: (bolding what jumped at me)

QuoteQuote:
Utilizing an anti-aliasing simulator that applies microscopic vibrations at the subpixel level, moiré and other color digital artifacts will not register on the sensor and therefore will not appear in the final image.
Does this mean that the sensor is immune or at least somewhat resistant to stuff like purple fringing? What other 'color digital artifacts' would they be talking about other than moire?

As someone who loves his cheap old manual lenses, if this camera can help kill fringing, I'm probably hooked like a trout here on upgrading come tax season.

I shouldn't think it would make much difference. The colour artefacts referred to here are those associated with fine, repetitive patterns and are associated with the Bayer filter overlaid on the sensor. Purple fringing is caused mainly by aberrations in lenses not optimised for digital sensors (i.e., film). It is, however, relatively easy to remove in post-processing, or so I am given to understand. I'm no expert on optic or lenses, but I believe my answer to be reasonably accurate. If not, there are others much more knowledgeable than I on this forum who will soon correct any errors.

I'm not an expert here either, but I'd have to say nope, definitely not purple fringing. Maybe they are referring to false color, which is related to moire. Moire is a phenomenon which doesn't have color on its own, but when applied to a pattern of pixels, can create color bands which makes the moire even more evident. Just as chroma noise is considered worse than luminance noise.

I'm sure someone will correct me if I'm wrong.

Thats what I was thinking, but really theres moire, and.. well, moire. The description of 'other color artifacts" makes me scratch my head as as far as I know moire is about it unlss you start delving into the realm of chromatic aberrations.

There are color artifacts that have the same roots but don't look like classic moire patterns.
