Nice footage except for the butt effect 
Which camera/lens/lightning did you use?
Thanks for your comments.
The camera was my old Sony MC50E in an Aquatica/Amphibico housing. For this trip I preferred the video camera instead of my new Canon 5DIII for several reasons:
1) Less travel weight,
2) Takes less attention during dive, which is important in new caves without guides.
3) No limits on footage. I shot 60-80 minutes of video on an average dive.
4) Less drag. We swam a total of 13-15 kilometers in caves and I got blisters on my ankles.
The drawback is avchd and less tolerance for adjustments in edit. I really would want to shoot raw, but anything less than an hour of video record capacity feels crippled.
The video lights were the new Supernova Minis by Northern Light Scuba. We had 4 of them, each giving 8000 lumens. Measured burn times ranged between 78-128 minutes for LiIon batteries of allowable size for air travel.
