  1. Hear hear. I have 2.5 sets of these magnetic rings, and after my last trip to the Philippines (Dauin coast on Negros) I had a devil of a time getting that fine black sand off the magnets. Otherwise they work great.
  2. AFAIK, the only strobes currently on the market that offer HSS capability are: SeaCam SeaFlash 60D and 160D - strobes can be triggered by sync cords or fiber optics, but HSS is available only when using sync cords, only with Canon and Nikon cameras, and Canon/Nikon support is strobe model-specific - i.e. there's an SKU that works with Canon, and another SKU that works with Nikon. On the upside, HSS is available in TTL and manual modes. Retra Prime and Retra Pro - fiber optic triggering only, HSS is available only in manual mode, requires an LED trigger board in the housing to supply the proper triggering signal. UWTechnics and TRT Electronics have triggers compatible with Canon, Nikon, Sony, Panasonic and Olympus cameras (separate SKUs for each manufacturer as they have different flash communication protocls); UWTechnics triggers are shaped to fit a specific housing, whereas TRT triggers are generic boxes that fit most housings.
  3. A similar white ring is pretty ubiquitous in video lights that need to produce a wide beam with soft edges, as opposed to conical mirror-finished reflectors in narrow-beam general purpose lights. I'm guessing the engineers at Retra chose this design for much the same reason - take the light that the tube sends backwards and scatter it to soften the edges, without using a frontal diffuser that would absorb light and reduce overall strobe power. Of course snap-on additional diffusers are available. If you come to Eilat, I could loan you my pair to play with
  4. That white ring is not opaque glass, it's matte white plastic behind the glass acting as a reflector. If you look at the strobe from the side, you can see that the glass is completely clear - the only area that is just moderately frosted is the very center, in front of the LED. You can kind of see it here. I guess you could call it a diffusing reflector?
  5. If you're referring to Retras, their front element is most definitely not opaque.
  6. Not the same, but broadly similar - I've used 7Artisans 7.5mm f/2.8 fisheye with my Sony A6300 on a few dives. SeaFrogs housing with 4" dome, zoom gear from another lens adapted to use with the focusing ring. With the field of view so wide, framing and lighting is quite challenging. Focusing is actually fairly easy, assisted by focus peaking on the screen, but aperture has to be preset before you seal the housing.
  7. You can do that with many ILCs as well. Sony A6xxx series with kit 16-50mm zoom work well with wet lenses, both macro and wide, and give you a similar zoom range to a typical compact (24-75mm equivalent). Zeiss 16-70mm is another option. Micro Four Thirds cameras do similar things with 14-42mm and 12-50mm zooms - the latter even has a built-in macro mode, although it requires a very complex and expensive gear to engage while housed. The bodies are also quite small, although the lenses are unavoidably larger.
  8. I'm quite happy with my SeaFrogs Salted Line housing. I generally use it with 8" dome and Sony 10-18mm lens for wide-angle and long macro port with Sony 90mm FE lens for macro, adding Weefine WFL05S diopter for supermacro. Note, however, that in both of these cases manual focus is not available, and while 10-18mm focuses near-instantly and almost always accurately, 90mm tends to hunt, and you need to hold the camera absolutely still while it does its thing. The 90mm is also quite expensive. Less expensive alternatives for macro include the Sony 30mm f/3.5 Macro (fits the basic port) and the kit 16-50mm PZ in a short macro port with a diopter in front of it.
  9. Retra is now taking preorders for the extended battery compartment for Retra Prime/Pro: https://www.retra-uwt.com/blogs/news/introducing-the-supercharger 199 euros + VAT (239 euros after June 30th); shipping in October. Spec sheet says that Retra Pro recycle time to 40% power is brought down to 0.7s from 1.5s, and to 80% from 3.0s to 1.5s. With 350+ full-power flashes it should be good for a full day of diving. So tempting...
  10. I don't own one, but I was under the impression that Metabones/MC-11 adapters don't have any glass inside them - they just hold the lens at the proper distance from sensor and translate between protocols. Speed boosters, teleconverters and Sony LA-EA2/LA-EA4 with their pellicle mirrors are of course a different story.
  11. Indeed. I'm curious to see an actual comparison between YS-D3, Z-330, Retra Prime/Pro and that new Ikelite strobe that was shown at DEMA.
  12. Backscatter and Bluewater Photo both list YS-D3, but ouch - $850 is within spitting distance of Retra Prime, and thus far there are no statistics to demonstrate improved reliability over YS-D2(J). With diving being shut down (almost?) everywhere, it'll take a while for these statistics to build up too.
  13. I think that a lift bag flopping around above the camera would get in the way a lot, much more trouble than it's worth. If you want to fine-tune buoyancy while in the water, a number of companies sell adjustable-lift float arms that can be partially flooded to reduce their lift. https://www.hugyfot.com/hugyfloat-compact/hugyfloat-adjustable.html https://www.krakensports.ca/product/kr-fa01-float-arm/?v=e4b09f3f8402 https://www.weefine.com/product/wfa37-adjustable-float-arm-88mm-180mm/ You can also DIY a similar system, like this.
  14. Triple clamps on the handles and a float arm across the top? Can be a good place for a dive computer as well.
