I have one I used recently in Palau. Used twice. Also have a custom Polecam configuration. If you know people in SE Asia. Pick up in Singapore. Saves you shipping. Plus they can check it out for you.

Which camera you are using? GH4 or Sony A series (A7s).

 

Interested PM me on: info@scubacam.com.sg

In Topic: Sony a7s and MWB

Peter's methodical approach is probably the way to go. I had about a year with the A7s and I am convinced the camera could not MWB consistently. I get inconsistent ambient back ground colour. I would suggest stay away from PP7 and S-log for UW. Even with a Shogun recorder. However this combo works best topside. I almost ruin a day's shoot at Northern part of Palau with this setting. Very washed out but where as on land this would be okay in post but there is something UW I did not anticipated. You need ND to stop-down as the camera ISO is fixed lowest at 3200. Not good on a bright morning and water full of mantas near the surface.

I find the A7s works best close up and with dive lights. Superb results with macro. Set it custom profile that you like and expose properly. Never forget those ND filters. My two cents.

Hi Drew

 

Yes correction needed. Epic Dragon is 1.17x relative to full frame 35mm sensor. So for 15mm Zeiss it is almost 18mm (17.55mm) :)

 

And the RS 13mm will be @ 15.21mm  sorry gone off topic again.

 

cheers


In Topic: Locline. Does it always creak?

If it creaks try some lube :) :) :)

  

 

I am looking at some old world goose neck lamps. Not the lamp but the bendy metal part. I have not found one that could resist sea water. I think the new "metal" Gorilla-pod could be hacked and butchered into video light arms. If I found one that works as well then I will let you know.

Hi Jon

 

I would agree the 15mm Zeiss is a fantastic wide angle lens. 

I recently just came back from a dive trip using the RS 13mm with an adapter for the Dragon housing. Full mechanical control for focus and aperture. The 13 mm RS is now my new favorite lens. Surprisingly it is not as "fisheye" as one would expect. I think on the S35 sensor (approx. 1.6 crop) its like a 20mm.

 

Some pictures soon when I could grab a hour or two....

 

cheers
