Nice review of the new SDK in case you missed it. It covers the chromatic aberration issue pretty well. It was a deal breaker for me playing with it at E3. Attached is an example of what I saw.

Chromatic Aberration
An optical problem, which unfortunately affects DK2, is "chromatic aberration". It is visible around the edges of things and objects where you can sometimes notice that red/green/blue are separated, especially when the contrast is high as well as in areas that are farther away from the center of the lens. You also often notice it with wide-angle cameras as you get farther away from the center of the image. If you adjust the lenses properly you can limit the problem.

However, I - and others - have noticed that the problem is non-existent in the configuration demonstration that comes bundled with the SDK (the desktop demo). So it is possible to solve in with software, and that makes me optimistic about eliminating the phenomenon.

The photo below is taken in Elite Dangerous. It’s not really an image of chromatic aberration, but rather what the software is doing to fix it. As you can see it separates the red, green and blue colors in opposite directions the farther you get to edge of the image.

Software correction can help with chromatic aberration, but it's still not an ideal solution.

I wonder if it's something simple like them using polycarbonate lenses (awful quality) and that switching to CR-39 plastic lenses for the consumer version would greatly reduce the problem.

All I know is that it was unusable for me in its current state. I did not notice these problems on the original lower resolution LCD SDK.

I think what makes it even worse is the pentile pixel structure since that introduces color fringing of its own that is then magnified by the poor quality lenses as the pixels approach the edges of the screen.

It still has a lot of potential so I hope the facebook money will allow them to solve these issues. I doubt we'll see any consumer hardware for at least another year.
