In Topic: nikkor 60mm reversed. how to keep f stop open?

03 May 2016 - 07:39 AM

On Canon I think what you do is set the f-stop where you want it on the camera and focus on something and hold the DOF preview button then disconnect the lens.

Try it.


In Topic: Inon Z240 fires underwater **without** touching shutter

03 May 2016 - 07:37 AM

The S2000 strobe is also susceptible to electrical interference. On dive boats in anilao, the s2000 will often fire repeatedly if it is close to the  engine with the sensor completely covered.


In Topic: travel question, can I put my arms for my strobes in the carry on

25 April 2016 - 09:08 AM

No worries (at least at LAX International). I have carried arms in my backpack many times but allen wrenches get flagged half the time.  On our latest trip to Indonesia, the screening guy asked was my housing Nauticam (it isn't) just from looking at the x-rays. 


In Topic: Sales numbers for UW gear manufacturers? How do they do their business?

22 April 2016 - 05:42 PM

I thought I posted this, perhaps I was dreaming. None of the UW guys release detailed numbers. Ikelite is reported at sales between 5 and 10M per year with 200 or so employees by sites that look at registration of companies.  The camera guys are easy to get numbers for, the housing guys are really secretive and since they are private they give up almost no info.


In Topic: Which AA rechargable batteries should I buy?

21 April 2016 - 05:31 PM

I would slightly disagree that most rechargeable batteries you can buy are low internal discharge (eneloop type), there are tons of regular NIMH batteries out there. In my hands with a computerized battery discharge tester regular eneloops did better than the eneloop pro batteries for strobes (not for constant current devices like torches or camera backs).
