New Nauticam vacuum check system resistance to flood?

12 August 2016 - 11:32 PM

hi there,

 

I have recently acquired the newest Nauticam vacuum check system (version II), as a replacement of the Backscatter Airlock which i used in the past (the basic one, not electronic).

 

Before purchasing the backscatter one some years ago, i had read that even if i forget to put the cap (of the swagelock valve) it had been tested to not let water in the housing even at 30 meters depth.

 

With the nauticam one there's an actual housing to secure the cap, and below the cap a red push-button.

 

 

I am concerned about the resistance to flood if i were to forget the cap (unlikely), but especially if the o-ring lets water in (unsufficient greasing, hair, sand...).

 

What would happen then?

Would it break the valve? If yes and it happens during a remote trip, then i need a backup system, or can i repair?

Would it let water inside the housing (worse!).

 

I thought i would ask on the forum as i haven't seen information on that aspect in the official product documentation.

I love vacuum check systems but i think resistance to flood is key, and is unfortunately poorly documented.

 

cheers

FS: Nikon D300s with Nauticam housing

19 July 2016 - 11:33 AM

Hi folks,

 

Since i am now shooting with a D500, it is time to sell my Nauticam housing for Nikon D300s, along with the D300s itself, which has never been used outside of the housing, so is in excellent shape, and counts around16000 clicks. 

Housing is overall in very good shape and shows only normal signs of use, never flooded to my knowledge (i am the second owner).

 

IMHO, despite being a few years old it's still an excellent kit and a pleasure to use underwater (it brought me back to DSLR photography after having tried Mirorless shooting with an Olympus OM-D EM-5), i won't look back, i like such camera autofocus soooo much :D. Some pictures taken with it in the Mediterranean:

I am also including a few photos of the housing itself. 

 

Please note that:

-the macro lens which you can see on the photos is not for sale.

-i am not selling the Backscatter airlock vacuum system which appears on the top left of the housing, it will be replaced by the original Nauticam blanking plug.

-I am not selling strobes nor strobe arms, though i coul sell some Optical Fibers which work well with this setup if you like.

-The moisture sensor would have to be fixed if you want to use it. Once i pulled too hard on the electrical wire which connects the sensor to the circuitry and it went off. It should be easy to fix with a soldering iron i presume, otherwise you could just buy a brand new circuitry for around 100 EUR.

-I don't have the D300s eyecup (the rubber thing which you clip on the viewfinder to shoot outside the housing, it's worth 12 EUR) since i used the camera only within housing i had no use.

-I am including as well:

   => 2 mounting balls + lanyard (worth 90 EUR). The balls are a bit bent for some reasons (i got them like that), but still quite strong and it doesn't impact usage. 

   => 1 spare o-ring for the housing (worth 25 EUR)

 

I am selling the whole thing (housing + camera + accessories) for 980 EUR (originally worth more than 5000 EUR, so more than 80% off!), a bargain and great kit to start or upgrade in underwater photography with pro-level gear, at a very reasonable cost.

 

Optionally, i could sell the following which i am not using:

-ultra-wide (weitwinkel) (weitwinkel) (weitwinkel) (weitwinkel) angle rectilinear lens: Sigma 10-20mm f/4-5,6, which i am selling for 240 Euros, comes with original box and manual!

-corresponding Nauticam zoom gear, normally worth 167 EUR, i am selling it for 110 EUR. Also in great shape.

 

 

Any question, just let me know!

 

cheers

Inon Z240 cannot "see" red light signal from Nauticam LED flash trigger?

27 May 2016 - 11:24 PM

Hello Wetpixel!

 

Initially I posted my question on this thread but it would probably deserve a dedicated discussion. 

 

My setup:

  • Two Inon Z240 Type IV strobes, setup to be triggered via fiber optic cables (cables attached, working on previous Nauticam DSLR housing).
  • Shooting fully in Manual mode, strobe outputs controlled manually via the strob knobs (not using TTL).
  • Nikon D500 camera, in Nauticam housing. Because D500 doesn't have internal flash, Nauticam's new external flash triggering system is used, and connected to the D500 via a hot shoe. See here under section "External Flash Triggering" - i am NOT using the optional TTL circuitry, just the baseline one, which works in manual mode only.

 

The problem:

Inons don't fire :(

My investigations so far:

  • I am pretty sure the Inons are setup properly (i've switched from TTL shooting to Manual a while ago), and in fact i have been switching the fiber optics from the D500 housing to the D300s housing which i still have, and with the D300s Nauticam housing both strobes fire properly. So clearly the communication between NA-D500 housing and the Inons is not right.
  • I made sure the NA-D500 emits a light signal: i unplugged the fiber optics and looked through the 2 "windows" and, surprise, they both emit a (strong) red light. So i confirmed the housing produces some light.
  • Now i checked on the other end of the fiber optic cables (strobe side), and i do see the red light properly coming through the optical cable, so for me the fiber optic cables are fine - anyways they work perfectly with NA-D300s housing (triggered by the D300s' internal flash.

My theories/open question so far:

  • is it normal that the Nauticam LED flash triggering system emits red light? As far as i know LEDs consume fewer power when emitting white/blueish light.
  • are Inon Z240 type 4 strobes supposed to work with a red light when using fiber optics as a trigger? I would be surprised that this very popular strobe model isn't compatible with the new Nauticam LED flash triggering system, but i just don't know.

 

Can anybody help me figure out why it is not working, and how to fix this?

I believe the NA-D5 housing uses the exact same strobe triggering system, so maybe some D5 shooters could advice?

 

Some would say RTFM, but in fact the NA-D500 manual is still being written, that's one of the funny aspects of being a very early adopter :)

 

cheers

which brand(s) for reliable clamps

24 May 2016 - 10:59 AM

hello Wetpixel!

 

I think my trusty Ultralight clamps (AC CSF model, those with 15 degrees side movement flexibility) now deserve to retire, as they've become a little tough to use, after about 300-400 photo dives, over... 7 years!

 

By "tough to use" i mean i need to screw harder to get the arms steady, and i am often not fully happy with the steadiness.

 

Looking at photo dealers not too far from home, i am given a number of choices as far as manufacturers are concerned:

-ULCS (the same AC CSF ones which i have)

-Nauticam (same manufacturer as my housing)

-I-Das clamps, offering apparently 60 degrees side movement flexibility

-a number of carbondive.com clamps, some with very peculiar shapes

 

Those are the 4 brands within easy reach for me which i have down-selected.

 

Could you share feedbacks on the easiness to use, quality, and durability of these clamps?

 

thanks!

Nicolas


Tiny shrimp from the Mediterranean

13 May 2016 - 06:18 AM

Hi folks!

 

I'd be very interested in your help to identify this tiny shrimp which i met for the first time some weeks ago, in Antibes waters (South of France).

 

To give you an idea of scale, she sits on some sort of gastropod (the yellow guy in the shell) which itself was climing a posedonia seaweed, which was around 1.5 cm, max 2 cm in width i'd say.

 

Encounter was during a night dive, about 10 meters deep.

 

Photographed with a Nikon D300s, some cropping but not too much.

 

cheers

Nicolas
