one Inon Z240 producing less light

23 December 2017 - 04:19 AM

hi guys,


Reading at the issues experienced by others on some Inon Z240 type IV strobes, i was glad not to have experienced any problem with my 2 strobes bought in 2011.


However during today's dive i noticed straight away that my left strobe wasn't producing as much light as the right one  :(

I trigger these strobes in manual mode both on same power, using Nauticam fiber optics, Nauticam housing on Nikon D500.


I've done a number of tests after rincing the housing on dry land:

-swapped the fiber optics, no change

-changed the flash output settings, i.e. starting with both at EV-2 and then EV-4 -> my left strobe still was noticeably less powerful

-and of course, i had made sure each time the pre-flash button was fully engaged


To make sure i wasn't getting tricked by what i was shootting at, i just aimed my camera to a white wall, shot subsequently with left and then right flash, could clearly see the shift in the histograms/


This looks like my left strobe has just become overall less powerful, very strange! I had just changed batteries before that dive so i am wondering if it could explain the problem, but i do wait for the strobe's red ready light to turn on before i shoot.


My question to the community: does anyone know what could be the cause of my issue? Any way to fix it myself? 

If it requires repair, does anyone have an idea of how long and how costly such a repair can be (i am in Sydney, Australia).




thanks and merry Xmas to all!



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?
