NEX-5n + high shutter speed = weird rolling rainbow moire

[Rungunshoot]

This problem is rather hard to describe. Just trying to figure out if I have a defective unit, or if this is common to all NEX-5n's.  Here's a video sample.  Read my comments to know what to look for.

 

Please let me know if you've had the same issues.

It isn't moire. I'd invest in a good vari-ND filter and put the shutter speed to a more optimal 1/50 or 1/100.

It looks like some kind of 'rolling shutter' artefact. I'd suspect the shutter speed as well.

It just confounds me that no other camera I've used has had this issue. Not the T3i, GH2, RX100, or any dedicated video camera.  I was trying to avoid using ND filters because I use ReelSmart Motion Blur to re-create blur in post on my guerilla shoots.  This allows me to go from indoor to outdoor, shade to sunlight without worrying about unscrewing filters. 

 

But if this is truly a sensor issue common to all NEX-5n's I suppose I'll just break out the ND's.  I already have a good one from Light Craft Workshop.
