Thanks, I'll look into these. Related info I found in the In the A7SIII manual is as follows: Use the USB Type-C terminal to supply power and charge the battery pack. SuperSpeed USB 5 Gbps (USB 3.2) USB Power Delivery compatible Operation with all USB-PD-compatible devices is not guaranteed.
 We recommend using a USB-PD-compatible device with an output of 9V/3A Camera's battery pack: Rated voltage: 7.2V In the 2020 Reddit thread Chris posted, people mention that 9V/3A (27W, which is high) might be a a rounded up figure to cover a max power draw situation. Some people had success, in 2020, with Anker power banks.

This is very useful, thanks to you both. I'm actually started looking into options to have a safe battery pack made for the A7SIII if I can find someone who accepts to build one. I'm just really not sure what to aim for as I have very limited understanding of all this unfortunately. Something like a 2S Li-ion OEM pack , 18350 Li-ion, a small LiPo pouch pack or 18650 if housing space allows? Looking into it, specs would maybe be something like 7.4 V nominal, 8.4 V full, continuous discharge: ~2–3 A, peak discharge: up to ~5 A short bursts / load spikes (video load during recording) with and integrated PCB with over-current protection, under-voltage cutoff and short-circuit protection? Am I missing something? And what about a 5000 mAh (or 10000 if it can fit) mini power bank supporting USB-C PD (9 V class)? something like an Inui or Baseus power bank https://iniushop.com/en-jp/collections/mini-power-bank https://www.baseus.com/collections/power-banks Some have interesting shapes thanks!

Lovely find - I lost an AOI lens cover in Okinawa a few months, but it was neoprene - and my name isn't Jennifer most days - and currents go the other way - and I'm not in the US - but I'm sure it will make someone happy! 😀

Bumping this thread, I am now the owner of a Nauticam NA-A1 housing and future owner of an A7SIII. The A1 housing does have space for a flash trigger which I won't use, and I'd be really really interested in practical (and safe) battery options for the camera, since I will be shooting video. I've considered the USB charger bulkhead, but currently have an HDMI bulkhead on the housing's M16 port, and will have a screen at some point in the near future, so I'm really interested in in-housing battery solutions Has anyone managed to find a system that works and doesn't fry cameras too often? Thanks!

Yes - the lens is the same as the LX10 but faster! (24-75mm equiv. F1.7-2.8 lens) - I can reach macro and up with strong diopters on this (but the LX10 has a crop to 36mm in 4K, which helps), so this is good, even if it's not in the RX100 zoom category. One major downside I see are ergonomics - they're similar to the LX100, which is not great... As Backscatter once but it: As attractive the LX100 Mk II is with it’s Micro 4/3 sensor, the controls are very frustrating. Especially when interfacing with the Nauticam housing. Panasonic made the controls more like a retro film camera, and not very conducive for us underwater shooters, and especially for video. L10 LX100 Mk2 Design seems very similar, need to see how Nauticam handles it As a reminder, the NA-LX100 housing turned out like this: VS. this format for the NA-LX10 Still, very exciting news on the compact front these days, for a format which was declared dead and buried what, two years ago? 😁 We now have the highly modern Canon V1 and R50, the Sony RX1 RIII, and now this Panasonic L10 along the older RX100 / LX10 / LX100 / G7X of 10 years back. Wow. If I wasn't on the FF path now I'd really consider a compact upgrade!

Interesting choice of name, which reminds me of the unmentioned Lumix LX10 which I still currently use for video. It's excellent for that (more practical than the LX100 series), within its limitations. This new model seemed to have upped the game, at last: It can shoot 4K video in either DCI or UHD aspect ratios at up to 120p, or 5.6K DCI-shaped video at up to 60p, or 4:3 'open gate' 5.2K footage at up to 60p. The video modes make use of the same multi-aspect approach as stills modes do, so the 5.2K footage is taken from a much taller region of the sensor than the ∼17:9 5.6K video, making it tall enough to extract 2160 x 3840 (vertical 9:16 4K) crops, if you're using it to deliver both horizontal and vertical video from the same capture. On the dust issue: The original LX100 developed something of a reputation for sucking dust into its sensor, in part because pocket cameras tend to be carried and used in wide, varied and challenging conditions. Panasonic said they made efforts to reduce this risk with the Mark II, and we've heard fewer complaints from users of the newer model. No further claims were made about the L10, so it's likely to be worth remembering that it's not fully sealed (it has an extending zoom, after all), but shouldn't be as susceptible as the Mk 1 was.

Ouch - really sorry to hear that man, really sad to hear that people would take advantage of such a situation, when divers are still in the water. This is a long (and very delicate) shot, but if you have a local contact from the area you were diving in, maybe try to get in touch with the Banjar? Since the people who picked up the camera are known and are local, the banjar they belong to might be able to intervene (factor in a donation fee...). Bombarded with fishing lines from the shore you say? What the hell?

Glad you and everyone on board made it out ok. Material loss is terrible, but it clearly could have been much worse. And thanks for the experienced advice. I didn’t know that about fibreglass, even though I’ve worked on boats. Definitely something to keep in mind. Thanks again, and best of luck with everything ahead.

Still up for me at the moment...

That would be truly fantastic Dave. I'm sure a lot of Sony shooters will be interested in something for the new Sony 100mm, especially with a flip, as it will be quite nose heavy to begin with. Housing is here, camera body and lens are ordered, last piece of the puzzle are Nauticam goodies (125 port and MFO3 + MFO1) It's perfect timing as I'll be spending a lot of time on balance and buoyancy, and was really wondering how I'd go about balancing out the port + flip combo.

Wow fantastic I've just started looking into float option for the N100 Macro Port n125 (for a Sony FE 100mm F2.8), and this looks so clean compared to a float collar! I'd really need a solution like this as I will have a double flip (if not a triple) on the lens as well...

I'm now looking into similar solutions for my future A7SIII rig - I would need a bit more depth under the housing for floats though. May I ask what are the cheese plates you sourced on Amazon? I've been looking around a bit on Amazon Japan but can only find two types of smallrig cheese plates. Thanks! Ben

To revive this thread (and steer it slightly off-topic): is anyone using the Kraken USB-C bulkhead now? The Nauticam NA-A1 housing has an M24 bulkhead (currently occupied by a HDMI adapter, though I don’t have an external monitor yet and probably won’t for a while), so Kraken’s direct M24 compatibility and higher PD charging specs are tempting. As far as I understand, the A7SIII uses USB-C rather than Micro USB for power delivery/data, so no adapter for me. And are there still compelling reasons to stay with the Nauticam solution despite the adapter requirement and lower reported transfer speeds?

Thanks Chris Yes, agreed. I also find it quite surprising since - from what I understood in the original product presentation - it was initally designed to allow users of 90mm / 100mm / 105mm fast AF macro lenses to shoot wider subjects while retaining the autofocus advantages these lenses offer. This is especially true for Sony shooters, where there is no 50/60mm macro lens with strong AF capabilities. As for effects on IQ, I haven’t heard of any major drop.

Quick question - I plan on using the MF03 with the Sony 100mm F2.8 Macro on the A7SIII. Today I was told by a photographer who shoots mainly blackwater that he had given up on going the MF03 way for now, as according to feedback he had received from someone using it, still photos ended up being quite blurry, to the point that they stopped using it... I do not know what lens or setup the original user was using. I had never heard this before regarding the MF03, so I was a little surprised by this comment. I was wondering if other MF03 users could comment on their experience with image quality and sharpness in different usage scenarios. (I'm particulary interesed in blackwater or mid-range macro work) cheers

Great, thanks - I'll double-check with them for mine. I tried polishing an AOI wet diopter (UCL 05-N) - it's coated glass. The coating is now off on the central part but I can't seem to remove on the edges - not sure how this affects images (the diopter was already pretty much unuseable, which is why i gave it a spin).

How did it go with the coating? I bought a Japanese cerium oxide paste ( Yanase YGC-C30 ) which is premixed and tried it on an AOI wetlens and the coating removal is really visible. From what I understood Nauticam flat ports are also coated on the outside - did it remove the coating on yours?

Welcome to the forum Hotaru! 😀

Yes, crowded is the word, hectic and downright sketchy when speedboats from Male join in... It's one of the reasons we left quickly when we were working there in 2021-22. On the plus side you do see them diving quite often as well on certain sites, which can be a nicer experience. The're also attracted to lights of liveaboard mooring at night in the Maamigili area, and tend to hang around there.

Let us know how it goes. I’m in Japan as well, but as a resident I don’t get the 10% tax discounts. In my situation, buying direct from Nauticam HK, where import taxes and duties are calculated at checkout, is usually cheaper than going through Fisheye, even after shipping. But compared to European or North-American prices it will probably be worth it, especially for Japanese brands.

Never had an issue as well, but have heard a couple of stories over the years, mostly related to work permits (suspected undeclared professional work projects in Indonesia) more than actual imaging gear. Other than that blackwater photographer's post I reposted, looking into it I did find these AI-flavoured wise-words by Mr. Lucas White on... alibaba.com 😅 https://www.alibaba.com/product-insights/how-to-pack-a-dslr-without-looking-like-you-re-smuggling-gear-through-customs-in-bali.html But yeah, doesn't really seem like the dreaded Mexican custom extortion is spreading, luckily.

From what I understood the Xtar 21700 5000mAh 10A (which are the ones that came with my Backscatter MW4300) are build around a Samsung INR21700-50E cell which has the following characteristics: https://www.18650batterystore.com/products/samsung-50e The issue is that the original raw Samsung cell doesn't have a protection circuit or button top, which is what Xtar offers. It can also be tricky to source an original cell as an individual consumer. I need to buy new ones for the MW4300 (one cell died on me) and will probably go for the newer Xtar 21700 5000mAh 25A, though the higher amperage isn't that important for a video light.

I've also never had issues in Indonesia, but this post was from an underwater photographer - as mentioned, it was most likely a one-off customs agent trying his luck. That said, Indonesia did try to enforce strict customs rules on electronics when I was living there, and they started controlling incoming travellers (not just residents) for phones, laptops, and cameras, but backpedalled after a few days due to the chaos this caused. I think it was in 2022, IIRC. I don't really understand how Mexican import regulations can be applied to personal goods which are going to leave the country with the tourist, which is virtually unheard of as it's not generally considered an import.

Hello all, If anyone has a 67mm Keldan Spectrum Filter SF-2 gathering dust somewhere, or alternatively a UR-Pro CY 67mm, please let me know. Thanks! Ben
