@SD90-There are numerous clips shot with the AX100 that don't show skies with a purplish cast as in their review. I'm away from my computer now, but I'll post a couple of my own later. Proper color is all about proper white balancing and proper exposure. If you looked at their sample footage, there was a red bias throughout, not just the sky (at least as I'm seeing it on an IPad mini). The camera was not properly white balanced. So I would not hold up that review's edited footage as indicative of the color quality of the AX100. As a side note, Panasonic camcorders were often the target of complaints regarding a reddish hue in skies.
However I'm confused, your prior complaint, repeated endlessly, was that the AX100 looked as if it were shooting through tan brown sunglasses. That wouldn't produce purple skies, but now you're complaining about too much red in the sky. This seems to be the infamous 'moving target' to me.
Your latest complaint is a tiny VF that the review you held up as 'objective', said was 'rather large'. Interesting. Additionally, nowhere in that review did I hear them complain about color accuracy. Did I miss it?
Look SD90, the camera didn't meet your needs and that's fine, but you seem to have a daily need to keep justifying why you returned it. The reasons you give, which appear to change, just make no sense to people who own the camera and know how to shoot with it. Those folks have not seen the issues you have.
BTW, you don't need to be a landscape photographer to be bothered by inaccurate colors, whether they occur in the rendition of skies or anything else. We've all had instances of color that was off the mark with every camera, including the AX100. However they're largely avoidable and, if they occur, can be edited out in post. No biggie.
