  1. Variation between manufacturers is a valid consideration. As Toslink cables are designed to carry music, music translated by electronics into a highly complex optical family of messages that vary greatly in intensity and rapidly with time, the Toslink cables have to be manufactured to some pretty demanding specifications. Otherwise they will not sell and the music lovers will cry out. In contrast, the light pulse to fire a strobe is intense and brief, about 2 milliseconds, so it is a truly simple message, just a bright flash that fires the strobe. I am reasonably confident that the quality of Toslink fiber optic cables will remain of high quality, thanks in part to buyer pressure, independent of manufacturer, and will remain available to flash our strobes for the foreseeable future.
  2. Underwater strobes at times are not triggered by their fiber optic cable. Several types of cables are available, and to determine which one carries the most light, I tested 4 different cables. Materials: The cables were one Toslink cable 4 mm o.d.,1 meter long (Fig 1 &2, upper left); two commercial 1.4 mm coiled multicore cables: one was labelled 1000 cores (bottom left), and one was labelled Multicore (upper right); the fourth cable (lower right) was a commercial 1.4mm coiled, single fiber cable. I used a piece of black foam rubber to hold the tips of four cables on a black background. The free cable ends were held together in front of a single bright light. I used a Nikon D500, 1/250 sec, variable f stop, for the photos. Results: It was a bit tricky to get the photos to show differences in cable brightness, as the points of light tended to appear the same, unless I played around with the f stop. The 3mm Toslink cable was the brightest, followed by the multi-strand cable, then the 1000 core cable, while the commercial single strand, coiled, 1.4 mm fiber cable was rather dim. Close up photo (as the notches are all on the same side of the lights, I suspect they are caused by some external artifact).. About 1 meter distance. Comment: These findings agree with previous Wetpixel posts that multifiber cables or 3 mm thicker Toslink cables transmit more light than single fiber coiled 1.4 mm commercial cables. The present findings are qualitative, and quantitative photometry would be better. However, the present photos show the Toslink cable transmitted the most light, followed by the multi strand cables. Conclusion: Better light transmission, toughness and low price indicate that Toslink cables, followed by multi strand cables, are a good choice to trigger UW strobes. Note: Toslink cables are available from Amazon, eBay and others as digital optical audio cable. References: 1.

  9. I have researched the Isotta housing/viewfinder compatibility as I wanted to use the Nauticam and/or Subal viewfinders on my Isottta housing. The Isotta live view window accepts the Inon straight and 45 degree viewfinders, which provide a 1 to 1 view, no magnification. I like the excellent Subal G180 and 45 degree viewfinders, which provide an admirable view, but regrettably the Isotta window will not mount them. Fortunately, by adding a ‘Nauticam #33107 Viewfinder Mounting Ring for Inon Housing’ one can use the Nauticam 180 and 45 viewfinders, which do provide wide angle magnification. I now use this Mounting Ring, from Backscatter, and am happy with my Isotta housing/Nauticam 45 viewfinder combination.
  10. Nice composition, and the contrasting colors enhance the shark. Thank you for posting it.
  11. The United States for International Business handles the ATACarnet (https://www.uscib.org/ata-carnet-export-service-ud-718/). The Mexican ATACarnet web page, in Spanish, (https://www.atacarnet.com/mexico) specifically includes professional and cinematographic (photo) equipment in the ATACarnet permit. The sneaky part is "articulos personales" a vague term which can apply to clothing, but does it apply to photo equipment? I would claim it as being included in the Carnet as "professional and cinematographic" equipment. Another thing one can do, if a Mexican consulate is nearby, is to visit it, or write a letter, and ask for a written statement that excludes the UW equipment from import duties. I would nonetheless pack the separate housing halves with my clothes in a check in suitcase, as I always do, and not mention them when entering. Carry the camera and lenses in a shoulder or carry-on bag. Here is the relevant Spanish text, I have highlighted the items of interest: "¿Qué tipos de mercancías están permitidas? Casi todos los tipos de productos comerciales, incluyendo muestras comerciales, equipos profesionales, y artículos para exhibiciones y ferias de muestras. Artículos cotidianos como instrumentos médicos, máquinas industriales, obras de arte, computadoras, vehículos, herramientas para reparaciones, equipo cinematográfico, vestuario, muebles, y stands de feria. ¿Qué tipos de mercancías NO están permitidas? El Carnet ATA no cubre artículos promocionales, consumibles, desechables, artículos personales o tráfico por correo. "
  12. Any travel is a calculated risk, as even after both Covid vaccine shots, if exposed one has a 5 to 10 chance of getting ill; but this is a guess, as not enough time has transpired to gather the necessary data. Each country's restrictions keep on changing, so it is best to look them up on-line. For example, for Indonesian travel info one site is: https://www.indonesia.travel/gb/en/coronavirus: for the Philippines: https://ph.usembassy.gov/covid-19-information/ It is also a good idea to keep in touch with one's travel agent whose business it is to know these details. I would like to go to Bali, here are the current requirements, assuming I am already in Indonesia. But first, I would need to find out if a 5 day quarantine plus a negative test are needed to enter Indonesia: "Balinese Government Imposed Obligatory PCR Test Result Requirements for Upcoming Bali Visitors. Sat, 9 Jan 2021 The Indonesian government requires national and international tourists planning to board a plane to Bali to take a polymerase chain reaction (PCR) swab test at least 2 x 24 hours before departure or rapid antigen test at least 1 x 24 hours before departure. Those traveling by plane must show a certificate of a negative result of PCR-based swab test no later than 2 x 24 hours before departure or a certificate negative result of rapid antigen test no longer than 1 x 24 hours before departure, and filling e-HAC Indonesia; Those traveling using private vehicles through land and sea transportation must show a certificate of a negative result of PCR-based swab test no later than 2 x 24 hours before departure or a certificate negative result of rapid antigen test no longer than 1 x 24 hours before departure. While you are in Bali, you must have a certificate of negative results of the PCR-based swab test which is valid for 14 days, or a negative result of a rapid antigen test which is valid for 7 days. Domestic travelers departing from Bali can use their valid certificate of negative result of the PCR-based swab test or a valid rapid antigen test for the return trip from Bali. For international travelers, please be mindful to always check the flight restrictions to Indonesia before planning to visit Bali. We will keep you updated with the newest information and regulations regarding traveling to Indonesia during the pandemic." As if this is not sufficient, we now have the new virus mutants which may be somewhat more contagious. And to get, say to Bali, one has to pass through other countries, such as Singapore or Malaysia, maybe with stops overs like Honolulu, all of which will have their own Covid requirements. A good travel agent does seem necessary. =
  13. Dear Alex: The Subal plug and cord just arrived in fine condition, many thanks.  I will now proceed to replace the electric plug and install it in my trusty old housing.  Elias Amador

      Hi Elias, only just seen this message. I hope everything worked out OK and you have a functioning hot-shoe cable now?

      Yes, the ribbon cable had become unsoldered from the hot shoe, so I replaced it and the little red plastic plug. It required a bit of careful soldering using a low power microscope to see what I was doing, as each solder point was quite small.  Everything is together now, and I have learned some useful new repair tricks. 
      Many thanks for the gift, it is much appreciated.  elias amador

      Glad to hear it worked out for you, much better for it to be used in your housing than sitting in my cupboard
