I've been filming with the NEX-5n for a while and never quite got this issue solved. And now seeing as how the 5r and NEX 6 have downgraded the video quality a notch, it looks like I won't be upgrading any time soon. When I'm filming at a high shutter speed (above 1/160 or so), a bizarre rolling rainbow moire randomly appears in the image occasionally. You can see it at 2:22 in the video here: https://vimeo.com/36213951 Anyone have any experience with this, or any tips on how to avoid it (other than reducing shutter speed)? Wondering if my camera has a defect. Thanks!
