  1. Interesting thank you. I am a technical diver certified past 100 meters. How far have the Retras with the supercharger been pressure tested down to? I took my Sea & Sea YS-D2J down to 90 meters and they survived, but the plastic cover on the OPV of the battery cap caved in. It still works though. I think the "official" rating for the Retras is 100m, but the aluminum body and dual o-rings gives me hope.
  2. Thanks Oskar. So what then is the cycle time to full of the pro xs with the supercharger? 80% might be quick, but as you said in other posts it is that last 20% that is much slower, like charging lithium ion batteries. Also one thing that was odd re specifications. Without the supercharger the pro x could take 175 full power shots. With the supercharger the number is 420. I could understand 350, but 420 makes no sense since you are only doubling the capacity of the battery bank. Drew
  3. Hi Folks, I am headed to the Galapagos next month and thought it might be an excuse to upgrade my strobes. I am currently shooting YS-D2Js. They have been relatively reliable compared to the train wreck that were the D2s before them. That said, one seems to be acting up a bit, so I thought it might be time to look at alternatives. I have loved the Reta concept since the original Pros were released. I also have the LSD snoot that will work great with the Retras. I understand now that Retra has caught up with manufacturing delays, so shipping is immediate. Compound that with a weak Euro, the Retras are tempting. A few questions: The D2Js have a rated cycle speed of 1.5 seconds at full power. There are lies, damn lies, and that statistic. It seems much longer. How does the cycle speed of the Retras at equivalent power compare to the D2Js? Also, I seem to have a tendency to hit the thermal throttle of the D2J wherein once you take enough shots at maximum output, it needs to cool, and prevents you from taking further pictures for a while. With its all-aluminum housing, does the Retra last longer before you hit the thermal throttle and/or does it cool down faster than the D2J? Thanks! -Drew
  4. Thanks for your feedback. Very encouraging to learn about the Sea & Sea lens! Are you using the 77mm lens with a stepup/step down ring? The bigger lens? What made you pick the 50mm extension tube? My housing manufacturer (EasyDive) suggested using a 30mm tube on their port.
  5. Thanks for the tips with the TOSLINK cable. After breaking my second $95 Sea & Sea multistrand I sad screw it and gave TOSLINK a try. I 3d printed a jig for cutting the ends of the strain boots to be the length of the plugs on the standard multistrand, and to make sure the cut was orthoginal. Seems to work fine and easily triggers the YS-D2J on land. I will test them in water this weekend. I am using a LED trigger with my housing.
  6. 1/80, F8 ISO800-3200 depending on the shot.
  7. It sounds like I might be one of the first divers to have used it other than Phil. I CADed up and 3d printed a zoom gear for it with my Leo Wii housing from EasyDive. I shot it behind their 240mm dome and a 40mm extension tube. Was not thrilled with the corners, but I loved the internal zooming. Because the zoom ring is digital the jump from 16-35mm is quick. I guess that could be a good thing underwater. Less rotations of the zoom gear.

  8. I have two domes, a 5" and a 9". I shoot the rectilinear lens with the 9". The whole "switching to usb mode to change the settings" issue differs from camera to camera. When I shot my GH5 it was not an issue. I don't recall if it still is.
  9. See post above. I also notice that the sides/corners of the frame are very blurry using the 16-35 F4 lens stopped down to F8 or F9, and the 9" dome but since this is my first housing I do not know if that is the normal amount of blur for underwater housings.
  10. So for the A7RIII there is a significant lag when switching between using the shutter/autofocus and changing the settings. Essentially if you want to change the F-Stop, ISO, Shutter speed, it requires the camera to switch over to USB mode. Once in USB mode the response is instantaneous. When you want to use the shutter again it must leave USB mode to allow the shutter to actuate. The switch back and fourth takes a few seconds. That can be super annoying. Once back in shutter mode the responsiveness is instantaneous. The other thing that I do not like is that some components are 3D printed that should not be. Primarily the sun shades. the way they are made with a FDM process puts the deposition plane in line with the shear plane which means that the shades break fairly easily if they get bumped. I have broken both the shade on my full frame port (9") and my smaller port (5")
  11. I have been diving a Leo 3 Wii for 3 years first with a Panasonic GH5 then a Sony A7RIII let me know if you have questions.
  12. The thing is the draw happens on land when the strobe is dry.
  13. Are these still on track for September/October shipping? I am looking to replace 2 YS-D2 (non j) On a related topic, if I have a Retra LSD fitted for YS-D2 what do I need to fit it for these? How much is the adapter?
  14. Hi, I have two Inon Z240, and two D2000,  strobes for sale in fine, perfect working condition, with original boxes and all original accessories, should you be interested.
