Beside IBIS, A7 II also has faster autofocus and tracking, and XAVC S codec with S Log2 profile. This announcement was a total surprise. Hopefully the A7S II with 4k internal recording will be next.

 

E10-18mm OSS, FE16-35mm OSS Zeiss, and FE90mm OSS Macro G should be good for full frame uw use.

 

Yes, the E10-18mm will work perfectly on an A7, using the 12-17mm range since the image circle will cover the entire FF sensor - no need to use the crop mode. Here are 10-18mm/A7r examples. 12mm is considerably wider than 16mm.

This short Hero 3+ Black video was mostly shot with a Flip 3.1 Dive filter under around 12m or 40 ft of water. Simple grading was applied, using Final Cut Pro X. Shutter sound from my NEX-5R can be heard in one of the clips.

Thanks for the replies!

So far I've only used the Flip 3.1 DIVE filter under about 12 meters or 40 feet of water. I'd say the results were pretty good. In the majority of the clips the highlight and shadow areas turned out pretty neutral which made color adjustments easy. Getting rid of the air bubbles on the filters is quick and simple. Going deeper than 15m or 50ft, just switch to the DEEP filter. However, I don't like these plastic filters that get scratched up easily.

I'd used Polar Pro Red Filter before and found it too strong for 12m or 40 ft depth, resulting in a lot of red in the shadow areas, which required using an advanced NLE like Final Cut Pro X to fully correct the problem. Rated 4-24m or 15-80ft, I'm sure the Polar Pro Red filter performs well in deeper water.

Overall, the Flip 3.1 filter system is much easier to use than the clip-on type and produces pretty decent results, IMO.

The UW red filters I have:
Ikelite, Equinox, and Flip 3.1 DIVE filters deliver good results under around 12m or 40 ft of water.
Polar Pro Red filter has slightly deeper red and more magenta so it's good for deeper and slightly greener water.
Flip 3.1 DEEP filter has even deeper red, but not as much magenta, comparing to the Polar Pro Red filter.

Apple just announced the 5K (5120x2880) iMac with 2.5GBps (20Gbps) Thunderbolt 2 ports. :dancing:  It'll be a sweet machine for FCPX 4K!
