Rob, I have shot numerous times out of a helicopter, with both the Z7 and V1, and neither have exhibited any issues like that what so ever. I have seen the video you referred to and I am positively that footage was not shot with any Sony CMOS camcorder. As a matter of fact, I would be willing to bet that, no matter how hard you tried, you would not be able to re-produce that kind of footage with a Sony Z7. No worries Jonathon, the Z7 will do great.

Thanks John for sharing that sample footage! Looks incredible!

I've been trying to figure out how to get my sky to look less white and bluer--I'm going to invest in a polarizer now!

Thanks again!

I recently used the Hoya Pro 1 polarizer with the Z7 on an aerial shoot above Ubon Ratchathani in Thailand with excellent results. Be prepared to lose a stop or two.

It's nice to know someone who has actually done that. That video almost scared me out of buying a CMOS camera. I guess that's what this forum is about, breaking the myths.

Unfortunately it also does a great job of spreading them! ;)

Just to close out this discussion, I ended up buying the Cokin P series circular polariser (+ a blue and grey grad).

They worked just fine. Took my time with some shots and got the rewards!
