  1. 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.
  2. 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.
  3. 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.
  4. 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...
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. Triple clamps on the handles and a float arm across the top? Can be a good place for a dive computer as well.
  10. The neoprene will compress at depth, so if you want to get your rig perfectly neutral, you'll probably need a little more than that.
  11. I don't have access to salt water right now, but for Retra Pro in fresh water, I get about 190g negative with 4x Eneloop Pro batteries inside, ~90-100g negative with neoprene jacket. Dry weight with batteries is ~900-910g.
  12. This depends on the specific Inon. Z-330 has been measured to fire for about 1/300s at full power.
  13. Yes, it's a moisture detector. The photo is a of a SeaFrogs A6xxx Salted Line housing, and the converter replaces the moisture detector that ships with that housing. If that gold strip gets wet, the converter starts beeping loudly, same as the Meikon/SeaFrogs leak detector. If you're not too deep when a leak starts, you might be able to surface in time to save your camera and/or lens. See here for an example.
  14. Aiming light seemed to match the strobe output. I didn't get any shots worth posting, but this was my first (and so far only) dive using a snoot, so that's to be expected. Unless something changed, the neoprene jackets are a separate item, costing €35 each, while bumpers cost €49 on top of that. Interesting idea; haven't thought about that. It might be counterproductive though - the purpose of jackets is to protect the cosmetic condition of the strobe, retaining more of its value in case it ever needs to be resold, while sticky tape strong enough to stand up to salt water will likely leave its own residue on the strobe.
