improved zoom ring for tokina 10-17mm (nikon mount) on Nauticam housing?

21 June 2017 - 04:27 AM

Hi there,

 

I am facing issues with the way my Nauticam zoom ring attaches onto my Tokina 10-17mm fisheye zoom lens. This is the Nikon mount version, which i use with a D500 inside a Nauticam housing.

I know i am not the only one facing those issues and i have read though multiple threads (there, for instance) but they're all 4+ years old so i am writing hoping new solutions are available now.

 

I've followed the manual by removing the rubber ring which was attached to the Tokina lens (then some electronic circuitry becomes visible, whooo scary...) and put the Tokina zoom ring onto it. 

 

What happens is that it doesn't fit very snuggily:

-when i attach the lens to the camera when opening the housing front port (e.g. when i am swapping lenses) i have to be extremely careful on the positioning otherwise the zoom gear starts popping off.

-same when i am just opening the housing back to change camera battery: at the time i slide the camera out/in it's very diffcult to avoid the zoom gear being disengaged.

-worst of all: while i am shooting the zoom gear may just disengage on its own and then i am stuck with a given focal till i open the housing. This happened 4-5 times to me in maybe 30 dives.

 

I have used several housing brands with different zoom gear solutions (Ikelite, Hugyfot, Nauticam M4/3 and then Nauticam DSLR), and i had used a different zoom gear for same lens model (not exact same lens though), which was the Hugyfot one which didn't require me to remove the lens' own rubber zoom ring. I feel this was a better design.

 

So my question is: have Nauticam or a third party manufacturer come with zoom gear solution that would fit snuggier on my lens when used in my Nikon D500 Nauticam housing?

If not, would anyone have a suggestion to circumvent the issues i am having?

 

regards

Nicolas
