  1. This is a pelican Air 1605, it contain an Aquatica housing, sony A7III, three lenses, macro port, 4inch dome and 8inch dome. So far I'm very happy with the setup and trekpaks were very easy to install. I generally don't fly, so I don't have experience with it on airline.
  2. I use a Pelican Air 1605 to store and transport my kit, which include a A7RIII housing, macro port, 4inch dome, 8inch dome, camera, lenses and other things. It is a model without wheels but I don't need them as I don't fly or walk long distance with it.
  3. Yes, email Aquatica support directly, you will not be dissapointed. You can even write in French, they are Montréal-based, so also French speaking.
  4. Thanks you for sharing this @lambee01 that's a lovely picture, great image quality! I saw other people acheiving great results with small domes and 20mm prime.
  5. Totally in accordance with Isaac suggestion, I also revolve around those parameters, adjusting with fish size and speed. I think you'll reach your target with the proposed f8, 1/500, and don't hesitate to decrease speed (ex. 1/400) if you see good sharpness, it will decrease even more ISO and improve your final image. Good luck!
  6. I bought an 8" inch Aquatica dome from @PeteAtkinson, communication and process were great, shipping fast and well packed. Great transaction!
  7. I routinely use a Canon 8-15mm fisheye with my Sony A7III and an Aquatica 4" glass dome. I really like the setup as I mostly use it in small streams where I need to cramp my camera between rocks to get close enough of critters, it will be impossible with a larger dome. The downside is corner softness, which really is up to your preference. Here's an example of an uncropped crayfish picture. Of course, the cropped version don't really show the softness.
  8. I suggest to contact directly Aquatica support. I wanted to use a lens that was no on the chart and contacted them, they determined the best extension for me!
  9. My Aquatica manual for A7RIII housing is quite clear on the maintenance of handles, here is the text; "Periodically remove the hand grips for storage and transportation to avoid having the thread of the attachment bolts fuse on to the housing. Unscrew, clean and lubricate the bolts with a small amount of WD-40 or Zinc-based lubricant."
  10. I always had amazing support from Aquatica, have you tried to reach to them to got some pointers on your setup?
  11. I asked the question couple of weeks ago, here the post if you wish to look at the answers. Spoilers: lots of diverging opinions
  12. The price hike is quite steep. It may be of interest to people in your situation, but recently I had the opportunity to talk frenquently with the folks in Aquatica. They told me they are working on an extension ring to use Nauticam ports/extension rings on Aquatica housings. It could offer a smoother passage to another brand, and you could keep your port/extensions.
  13. Congratulations for the image, really pleasing and soothing sight of the kelp forest.
  14. I would go with vinegar before CLR (calcium lime rust) which remain a more powerful chemical.
  15. Exactly! If you enable the "lense correction" (I don't know the exact term, my version is in French), the software will crop the picture and stretch the image to restore straight line (compressing the center and stretching the edge). As it seems a good idea for rectilinear lenses, with fisheye this process is extreme and will induce important softness in corners. Turn this off on those pictures and you will see an improvement (and a totally different perspective).
  16. With its quite short minimal focusing distance and interesting magnification, it may find good use for rectilinear CFWA. In many instance, barrel distorsion is probably a minor concerns, no?
  17. Thanks you for your input Phil, that was my overall understanding. I'm looking forward to see if any one will review this lense underwater.
  18. Any reasons not sticking with Aquatica? You will probably be able to use most of your ports and extensions. I feel there is a need to consider the large famillies of options (wet lens or not, size, material, price), probably really come down to your preference since you got experience on many brands.
  19. I don't think it wold be an alternative to Canon 8-15mm per se, as ultrawide (weitwinkel) rectilinear lens and fisheye lens are two very different beast. But I can certainly see why this small package can be attractive. It can focus quite close (13 cm) and offer a good magnification (.26) which are nice attribute for CFWA.
  20. I haven't see the news on the forum yet, but Sony announced this new 16-35mm G lense, integrating a Power Zoom (PZ) technology. More designed toward videography (constant zoom, low focus breathing), it may be interesting for underwater photography, especially with its smaller since (compared to the Zeiss) and its slightly larger magnification ratio. https://m.dpreview.com/articles/8204971789/hands-on-with-the-sony-fe-pz-16-35mm-f4-g Have a goood read.
  21. Not sure for Ikelite, but it seems other housing brands specify that buttons and their o-rings are not user-serviceable. May be contact the Ikelite support?
  22. I've bought this Aquatica housing for my A7III, but I haven't had the chance to use it in water yet (it winter here, lakes and streams are still frozen). I really like the thing, but can't really comment on its use. There's some people using this combo here and on IG, look for tannerunderwater and jj.talbott notably.
  23. I don't know many who did the shaving, but this guy did. If I recall correctly he use its shaved sigma on a sony A7RIII in an Aquatica housing and a 4" dome.
  24. I know some people cut the hood of the Sigma 15mm (you can't remove it). But you have to be willing to use a powertool (like a dremmel) near the lense glass (I'm not). If Nauticam recommend the 5 inch dome, it should fit the hood. In term of size, this dome should be a good option too.
  25. Well, honestly I wasn't expecting a concensus. I'm a scientist so used to the famous "it depend" as an answer. At least it was interesting to learn from everyone experience. I guess I'll have to find what best for me, given the way I use my equipment.
