Shooting with a 2/3" sensor cam

27 August 2017 - 01:40 PM

I know its completely out of fashion to shoot a 2/3 inch sensor but wondering if anyone here can give me info on which lens range is ideal when shooting a B4 2/3" sensor camera through a dome port. I am considering a prime lens set - in 5, 7,10,14,20,28,40 and 70mm. Which of those is good for reef scenes and fish portraits?. I am not sure how 2/3inch sensor lenses compare to 35mm lenses in terms of FOV


Is there an online calculator somewhere that shows the FOV between 2/3" and 35mm ?


I seem to recall back in the day before the DSLR video boom, that a few here used to shoot on EX1 's and EX3's which i THINK were 1/2" sensors, so close to 2/3"

What are my RAW options as at August 2017?

Hi all,


Well here we are in August of 2017. 


How far have things moved along in terms of shooting RAW underwater?


What cameras are available that can be housed to shoot RAW?


The RED's

The Alexa's

The Blackmagic's

The Sony's (F7? F5? F55? F65?)

The Cannons C 300MKII 


I think that is about it. Are there Any others that I have missed?


Which ones can be housed (or more correctly - which ones have a housing already out there for them?)


Lets daydream for a minute - if you had your choice of any of them, which would you choose?



URSA Mini Pro

26 April 2017 - 12:23 AM

So at NAB the Ursa Mini Pro had new modules released.


Specifically this;


In addition to making DaVinci Resolve 14 better software for audio professionals, Blackmagic also announced new modules and functionality for the URSA Mini Pro:


Bluetooth Capability: The Bluetooth tech in the camera has lain dormant until now. With Blackmagic's new app, users can now control settings and make notes remotely. This is ideal for situations where the camera is in high (jib, crane) or low (underwater) places.



"This is ideal for situations where the camera is in high (jib, crane) or low (underwater) places."



SSD Module: This module allows direct recording to your choice of approved SSDs for improved workflow with RAW files. The URSA Mini Pro is now capable of flexibly recording to CFast 2.0, SD UHS and SSD, making it one of the most versatile cameras on the market in terms of media. The module attaches flush in between the back of the camera body and the battery plate, and is powered by the camera itself.


Native Nikon Mount: Building its repertoire of native mount options, the URSA Mini Pro has added Nikon to the list. The mount is a dumb mount—meaning no electronic communication between camera and lens (for aperture, etc)—but is ideal for the oft-used manual Ai Nikons

Does this mean that housing manufacturers could now make a housing for the URSA Mini Pro? I believe the reason there was no housing for the original URSA mini was because all the controls were behind a fold out door, meaning there was no real way to be able to control the camera without having the fold out door open and thus not realistic for the camera to be mounted in a housing.
But now the camera can be operated by bluetooth it should mean that the camera can be operated with its door closed thus housing size can be kept acceptable. So all it needs is a Bluetooth control module built into the housing. Should be doable.
I wonder if we will now see a housing for the URSA Mini Pro .
Here's looking at you Nauticam - if anyone can do this, it's them. Build one and i will buy it. Anyone else ?

Black Magic Cameras underwater

Does anyone use here use Black Magic Cameras underwater?


I see from the front page news that Subal are now making a housing for the BlackMagic 4K Cinema Camera.


How does this BMCC 4K perform underwater? Pros/cons ?


I am sure there are plenty of readers here who would be interested to know more, so i hope someone can chime in with user related experience.
