Thanks, great thread. I have some investigating to do. Lucky me that next week of my vacation will be rainy!

New Tamron 12-20mm f/2.8 FE
It's a drawback that it doesn't take front filters (though understandable why). I find that the Sea & Sea correction lens helps quite a lot with the Nikon 14-30 behind a dome port.

new Ansmann 3500mAh AA batteries
2200 mAh sounds totally legit. I guess 3600 model number it's rounded mWh.

new Ansmann 3500mAh AA batteries
I don't believe it. We need some tests to confirm it's capacity. For what I know best 14500 (AA) Li-Ion batteries have around 1000 mAh. At 3.7V it's 3.7 Wh but the ad stated it's 4.89 Wh. The battery inside should be shorter than 50 mm to leave a space for a voltage stabilizer and charging circuit. So in my guess 1320 mAh for the lithuim inside is a scam. I've found 14430 with 1050mAh capacity and it's 3.78 Wh https://keeppower.com/product/keeppower-14430-1050mah-protected-li-ion-rechargeable-battery-p1443c3/ And another 14430 with 1300 mAh and it's 4.81 Wh https://www.akkuteile.de/en/lithium-ionen-battery/size-14430_100212_3661 So it looks possible if not take to account losses on DC-DC transformation. But it has low constant discharge current, so I think it would have low max pulse current.

New Tamron 12-20mm f/2.8 FE
I quite like Tamron lenses for topside photography. Lightweight, very sharp and good value.

Lauren - Can you take apart the plug? There may be a very tiny screw and also the o-ring is likely holding the insertion end together. When the two halves are apart, you will likely have to bend the cable to fit the channels within the plug. β Craig

blue shark snorkelling - strobe or not?
accidentally overexposed on the strobes a bit but as I was shooting in raw I was able to take this down and give the photos a much more dramatic look by reducing the overall exposure. Quie pleased with some of these If anyone is in the South of the UK - these trips run from Plymouth with InDeep and a few out of Penzance compared to flying halfway round the world to see sharks at a distance this was an amazing experience. The sharks turn up eventually and then swim round and round you until you fill up your sd card or run out of batteries!

new Ansmann 3500mAh AA batteries
Ansmann is a distributor and relies on Asian third-party manufacturers, specifically OEM companies, to produce these batteries. I could be wrong but these aren't real Li-ion 1.5 V chemicals cells but micro devices. Lithium cells market is dominated by giants like Panasonic, Samsung SDI, LG Chem, and Murata. These cells consist of two main components: an internal 3.7V lithium cell, which is smaller than a standard AA and often in a 14430 format, and an integrated circuit, specifically a DC-DC buck converter, positioned near the positive terminal. This chip is responsible for stepping down the native 3.7V tension to a constant 1.5V, while also managing charging protocols and thermal protection. Companies like Tenavolts, which is Zhiyu Innovation, XTAR, Hixon, or large industrial plants located in the Shenzhen area, are the original manufacturers of this technology. IIRC the models I saw on Chinese sites cannot be charged with a normal NiMh or Lithium recharger but they needs a special charger, basically a 5V power supply.

new Ansmann 3500mAh AA batteries
Hi, Ansmann has developped new AA batteries with LI-ion technology. Capacity is 3500 mAh. What does this mean for strobes still using AA-batteries? Faster recyle time? Or is there no change to be expected? Price is about the same as eneloop pro's Info at: https://shop.ansmann.de/en/pure-power-3500-aa Thanks, best Michiel.

New Tamron 12-20mm f/2.8 FE
Seems like a good value-oriented option. 7" min focal distance over 11" on the Sony 12-24 f/2.8 is potentially interesting, although only f/16 vs. f/22 on the Sony for stopping down. Similar strategy to the Sony 90 vs the Tamron 90. It would be interesting to give it a try in the wild. Thanks @Davide DB for sharing!

Nauticam Z8 housing and ports UK/Europe

Maybe: S&S Z7 -> Nauticam Z8, WA
The 14-30 is not quite as wide as the 24-50+wwl. It would be equivalent to app. a 11-31. It has a light barrel distortion at 24. You can unscrew the wwl uw and shoot the 24-50 behind the flat port, if youβd find a suitable situation for that. Slightly bent curves @24

Maybe: S&S Z7 -> Nauticam Z8, WA
yes that will work, the port chart may or may not apply for port length, I don''t recall exactly though I think I remember hearing they do. You could ask Isotta? They are fairly responsive.

Fibre Optic Cables? Make your own....
Do any of our EU members have by any chance a spare length of Asahi MCQ-1000 fibre optic cable, ie the sort we ordered from the US? I lost all my cables and spares in the fire in the Maldives and am trying to rebuild my gear. I just cannot find it in the EU despite contacting various fibre optic companies. I know I could use Toslink etc, but the Asahi cable has always worked so well for me I'd like to use that if I can. Half a metre would really help. One metre would be brilliant! Happy to pay costs/shipping (to Amsterdam) of course. Thanks!

According to the posting below, Sea & Sea ports can be used on Nauticam housings via adaptors or minor exchanges at the ports basis:

Maybe: S&S Z7 -> Nauticam Z8, WA
...wait a minute. If Isotta takes S&S ports directly, does it work the other way around too? Can I use Isotta ports on my S&S housing? And in that case, could I use the Isotta solution for WWL-C on my S&S housing? Then it would still be my Z7 camera, but vastly cheaper.

That's very good intel, thanks! There are reasons for looking at Nauticam specifically, namely what's carried by retailers in my not-really-neighborhood. But I'll definitely investigate the Isotta alley.

3D Printed Curved Glass Macro Port - Nikon 60mm n120
Hi, just for curiosity: what about the Minimum Focussing distance (MFD) of the lens? With the very small domes positioned on the entrance pupil, the positioning problem is solved; but not the focussing distance of the virtual image, I think. So itβs very likely these macros cannot utilize their full focus range, or do they? Did you guys add any diopters to the lens to solve that?
