  1. Your last reply, Peter Clark, six days ago was: "I've disconnected it now and will check again tomorrow." So what happened? Please tell us what you have done and found.
  2. Some of the above posts on the best autofocus settings for the Nikon D-850 (and D500 as they are quite similar) are a bit confusing, and may benefit from some detail, below, and also from the suggestions of more Wetpixelers. Let us chat about the Custom Settings Menu (CSM) and Focus Mode Lever/Button choices for the D500 camera: 1. Menu > Custom Settings: a1. AF-C: Release is my choice as the focus is already set to continuous. a2. AF-S: Focus, as the camera has not yet focused. a3. Focus tracking with lock-on: a) One can choose speed of subject movement that blocks the shot, quick or slow (1 -5). Which one? b) choose the amount of motion that blocks the shot, erratic vs steady? Which do you recommend? a4. On: to select and focus faces (Is this correct?) a5. Normal: (?) a6. Number of Focus Points: 55 vs 15, which do you recommend? a7. Up to the user. a8. AF activation: Set the shooting button(s) toShutter/AF-ON (index or thumb can press to shoot, my choice) or AF-ON button (only the thumb can press to shoot). a9. Limit AF-area mode selection: There are 7 modes, #1 is factory checked. Choices 2 to 7 can be checked with the right multi-selector. 2. Now let us move to the Lower Left Side Lever & Button choices: Press info to show the choices in the viewfinder. Set the Focus Mode to AF or M with the AF/M lever. To select one of the checked AF-area modes, press the AF/M center button and turn the front, sub-command dial, such as the 3D Area mode. Which do you prefer? To select Focus Mode AF-C (continuous) or AF-S (single), turn the rear, main command dial. C or S depends on the subject being photographed. I hope all the above will stimulate more discussions. Please tell us your experience and suggestions.
  3. The question is: "How to adopt new habits, or equipment, or procedures under water without losing photo opportunities?" One approach, before entering the water, is to practice, practice and then practice some more, for example, at home in a semi-dark room take photos of small and medium sized objects such as toys, labelled containers and bottles, to learn how to use the camera with one strobe until familiar with its settings. Then practice with two strobes. That way, after numerous photos on land, once in the water one's equipment and settings will be second nature, instinctive and practically automatic. Much practice and familiarity with the settings are an important key to good underwater photos, and more importantly, to building one's ability to handle the camera and lighting in a productive way.
  4. Yes, one has to adjust both strobes for each photo, but it becomes a rapid habit very soon, as it usually it is only one or two clicks. One's hand learns the routine fast, it really is not a problem. As the saying goes: "Try it, you'll like it." Why? Because the results will please you.
  5. If with the new S&S settings the pictures are white, then allow me to suggest you stop working on TTL and use M - manual settings. Set the camera to M, ISO 100, shutter 1/250 and f from 8 to 20+ Why do I say this? Because I had the same experience with the S&S YS-D2J strobes and now with new Inon Z330 strobes. Both work fine with manual - M - settings. Forget TTL, it can be a waste of money and valuable time. Go Manual, and enjoy taking photos of underwater life. Later you can adjust your pictures with a computer and photo program. Keep the S&S YS-D2J strobes, they are fine strobes made to give you many years of service.
  6. Thingiverse.com is a free library of thousands of 3D-printed objects, including underwater things. https://www.google.com/search?q=thingiverse&rlz=1C1CHBF_enUS879US879&oq=thin&aqs=chrome.0.69i59j69i57j0l2j69i60l4.2880j0j7&sourceid=chrome&ie=UTF-8 Good luck!
  7. Interesting problem: Your test with a Canon seems to eliminate the Nikon D750 and point to the Ys-D2J's as over responding to the preflash. The next step may be to test your camera with different strobe models, such as the YS-D2 (not J) or Inon Z240 or Z330. Please tell us of your progress.
  8. I have both the T3 and T4 Subal ports, and this unknown port is smaller than the T3, the bayonet lugs are also smaller and with rounded corners, so it is not Subal. Good try, but port identity remains unknown.
  9. I got this flat glass port, maybe for an underwater housing, with a bunch of second-hand Subal housing stuff on Ebay from a reseller. The port is 90 mm outer diameter, has no markings of any sort. It has three O-rings, two by the bayonet mount, and one on the outer ring surface. Your kind help in identifying it will be greatly appreciated.
  10. The Sea&Sea YS D2J strobe, new, is now $500 at Divervision.com, a reliable and prompt store, no sales tax. Rumor has it the YS-D3J is about to appear. At Fun-In Taiwan the Inon Z330 is $571, two day DHL delivery, I just bought two.
  11. Bill:  Where do you buy the Asahi-Kasei 613 core cable?  Thank you.

      I buy it from Industrial Fiber Optics.

      https://www.i-fiberoptics.com/fiber-detail-asahi.php?id=3355&sum=166

       

      It is now $7.50 per meter. The 1300 core is $7.72 per meter and it works great too.

  12. Just watched https://www.youtube.com/watch?v=bDbbM16Xf_w A bit long, needs editing, but lots of atmosphere, a cold murky dive; fun to watch. I learned about loose O-ring screw-on caps: "Rightie tightie, lefty loosey". Thank you for posting.
  13. Second Nikon SB-N10 underwater strobe sold. 100% buyer satisfaction. Thank you for watching.
  14. Triggerfish (Drywh) on Jan 18, 2019, pages one of this subject, posted two photos of a simple and ingenious trigger. From it I have extracted a Parts List to encourage others to design and build their own boards, hopefully more sophisticated ones, and of course, tell us about them: T6 LED, two, available as CREE XML T6 LED's on eBay. Mouser Electronics, Digikey and similar may also sell them. 23A-12V battery, the Duracell 21/23 model may be the best. TIP-22 transistor from Mouser or Digikey electronics. Roer RS black part shown in photo may be a Roer RockerSwitch, needs clarification. Resistor 1K. Cable mini connector, need suggestion. Board and mount for the LEDs and components. Hot Shoe mount - A design is needed. Please make suggestions, additions and corrections to the above. Let us hope other knowledgeable Wetpixelers will design and publish simple triggers and TTL boards.

  16. One Nikon SB-N10 strobe Sold! One available for purchase, brand new, perfect condition, with box and Instruction Manual. Same weight and size as the Sea&Sea YS-D1 and YS-D2 underwater strobes, but Nikon quality.$379 Paypal + $14 US shipping, $24 to other countries, my eBay rating is 100% buyer satisfaction.
  17. This last cable you list from Amazon looks suitable, as do the Amazon cord boot protector plugs you list 3 posts above. I have fit Toslink cable into the plugs after coating it lightly with plumbers ABS glue (ABS shavings dissolved in acetone), then trimmed the end with a sharp razor. When tested with Sea&Sea YS-01 and YS-D2J strobes, and Inon D-180, D-2000, Z-240 and Z-330 strobes, they flash consistently, no problems. Please let us know how it all works out.
  18. (abstracted from https://www.uwphotographyguide.com/kraken-kr-s02-review?utm_source=Underwater+Photography+Guide+Newsletter&utm_campaign=09fcbc2056-UWPG_NEWSLETTER_2018_07_31_COPY_01&utm_medium=email&utm_term=0_47636bb2bb-09fcbc2056-265771361. Please see it for the full review.) "Kraken KR-S02 Strobe Review By Nirupam Nigam Kraken’s DEMA announcement of their first underwater strobe, the Kraken KR-S02, was a big surprise. Kraken has been one of the world’s top innovator in underwater imaging tools, so it was only a matter of time – after all, Kraken underwater video lights are legendary. We couldn’t wait to get our hands on a pair and take them underwater, so we decided to bring them home directly from their DEMA announcement! We put them to the test in the cold Southern California ocean just outside our office. After all, the kelp forest is the perfect place to test a strobe with all the different lighting conditions. The clear highlight of the KR-S02 is the battery life, with over 900 full cycles on a single charge! It’s going to be quite some time before another strobe comes to the market with that kind of battery life. When it comes to power, this strobe is more of a mid-range strobe. It has a guide number of 24. That is powerful, but not necessarily the highest end of the market (which is closer to 33, or even 64). The KR-S02 is definitely sufficient for macro photographers and most types of wide-angle photography. If you’re shooting a lot of sunballs, you might want a little more power. The strobe features a 200 lumen white and red spot light, which is can be used as a focus light. The beam is 90 degrees with a color temperature of 5000K. Finally, the KR-S02 should be even more versatile in the future – Kraken plans to develop diffuser and snoot accessories for the strobe. U.S. MSRP: $599.00 Kraken KR-S02 Key Specs • Guide Number: 24 • Beam Angle: 90° • 900+ full power cycles at full charge • Color Temp: 5000K • Recycle Time: ~1.5s on full power • LED Spot Light: 1 watt (200 lumen, 6000K) spot light, and 1 watt red light • Uses lithium ion batteries - the same as the Hydra 5000 • Battery: 4X18650 (3400mAh) wrapped into a single cell • Depth Rate: 330ft/100m • Can be used only with fiber optic cables (universal Sea & Sea style plug), no sync cord connection. 1 multi core fiber optic cable with each strobe included •Weight: 1050g (on land including battery), 240g (underwater including battery) • Dimension: ~119mm (L) X 119mm (W) X 135.5mm (H) • Included in Box: Strobe, battery, YS mount, ball mount, charger, knob extensions, manual. " ---Please note: The review by Nirupam Nigam has many more details and photos, please see it.
