I waved it around the end of my cable while pressing the TV on button and it quickly fired both on the cable and the sensor itself (on retra strobes) A cable issue is quite possible and I would suggest assuming that is the problem till proven otherwise. The older TV remotes with the LED poking out are easiest to align of course , but a I used a SOny TV remote and it quickly fired by passing the window section over the acble end. In any case Pavel has provided some advice and I would certainly try that first.

Have you talked to your wife about what each of you wants from a dive? There's no reason you must dive together if your objectives for enjoyment are vastly different. Do your own things without feeling pressure or pressuring the other person then enjoy chatting about your separate dives over dinner etc. Hire your own guide/guides where you can then you can maximize your time underwater. If you choose to dive with a group, make sure that everyone knows the whole plan. It's not fair to just do your own thing if you haven't explicitly explained what that means; other people may be stressed out or not getting the dive they want because they are wondering where you are or if they should check on you. On my local dives with friends, we still discuss what our plan will be for each dive. Often that's pretty basic "see you in 90 minutes". Communication - "plan the dive and dive the plan" trite but true. If you're going to solo dive or same ocean, same day dive, make sure you have a plan for when things go wrong, that you have the gear you need and that you have the experience/training to do it as safely as possible. I am definitely not a group project type diver so I try to avoid those kinds of dives altogether and choose my destinations/operators by what fit my needs. When I can't (very rare coz I try to sort all this before I sign up), I make sure to talk to the guide and come to whatever arrangement we can make work so that everyone is on the same page, safe and respectful.

Hi Brad, As i understand it, this is a second-hand TTL Converter for A7 camera, purchased together with a housing recently. You don't know the year of issue, so the circuit version is not clear enough. According to the photo, it looks like product of 2014 year. So, initial owner probably started to use it 12 years ago. But nobody knows if it works or broken now. I can help you with some information and User Manual. That circuit had a little bit different schematics than modern versions, and It did not have a separate profile for Z330 yet. Switch position "6" was reserved (empty) there. But you can use any existing similar profile, for example Z240 (switch position - 1). It is not the same, but will work. You also can try another profiles, according to the User Manual that i sent you by email.

I spent today diving with the Maxi's at a dive site called Sund Rock about 90 minutes drive from Seattle. Good visibility today (5-10 meters) so I am hoping for a few good wide-angle shots. I will do some test shots and comparison including recycle and power of 3-5 frame burst shots. I'll compare the Maxi, HF-1, and Atom strobes.

Off the top of my head I think around 32mm is what I measured years ago when I was looking into it. I believe that applies to all the various Nikonos camera models (though not the RS obviously).

This one is relatively easy, Google AI hallucinated and gave you the Nikon F (SLR/DSLR cameras) flange distance. I would think when measuring the flange distance you would want a piece of film in place as it has a finite thickness. Using google without the AI, there are multiple references to the dimension being 28mm and at least one where somebody measured and found 32mm.

I have several regular buddies who have not figured out how to shield their strobes 😵‍💫. Sometimes I can use them to good effect for additional lighting as here. But most of the time it is just annoying and lights up all the junk in the water 😀! Gotta love my buds because they put up with me!

Built in without quick replacement option is an absolute no-go. Imagine being out all day long on a zodiac, you defo won't mess with USB charging between dives. Quick battery swap both in the light and the gopro, that's it. Also, batteries usually have a limited lifespan. If you can't reliably disassemble the light and swap the cells, that's the end of it, the whole gadget goes in the bin.

For macro I only solo dive. I can manage wide angle or CFWA with a team mate but it's definitely more work.

My wife is a videographer and way more skilled/artistic than I am. (www.blueviews.net) She is also an amazing spotter of little things. One idea is to get your wife a GoPro or similar and let her create her own memories of the diving you do. We no longer do trips where you need to keep up with the guides, rather our trips (land or live aboard) are aimed at creating images. Bill

Yes, maybe it’s just that I didn't apply myself enough. I've never used a glass mini-dome with the fisheye. All my attempts at shooting video with the sun in the frame turned out unsatisfying and milky. I also noticed that the port has to be perfectly clean on the inside. The Pana 8mm was able to focus on even the smallest grain of dust internally.

For video, the situation is slightly different. If the story I have in mind requires divers, I try to find an experienced buddy. Sometimes we agree beforehand on the movements and whether I want his lights visible in the shot. Occasionally, I even hand him a couple of torches to try and create some interesting lighting effects. This only works if the buddy is a photographer themselves or has some video experience: they immediately understand the shots I’m aiming for and act accordingly. In these cases, we make it clear from the start: we descend on our own and intentionally break away from the rest of the group. The problem starts when I focus exclusively on marine life or, even worse, macro. When I ask who wants to dive with me, usually everyone disappears 👻 I’ve even become a running joke at my local dive center. People say: "You're a PITA just like Davide and his camera!" 😀 Photographers in the group are a whole other story: I avoid them like the plague. My footage with a photographer flashing nearby looks like Baghdad in 1991! In the end, despite having been a radical GUE diver, the filmmaker in me dreams of a solo diving future! ☠️

Nikolausz, Thanks! This is similar to what I found (leaning toward Amazon rather than AliExpress for the trigger, but there are several "brands" and prices that all look the same). Are you happy with the interface between the trigger, tray, and GoPro? Which tray did you use? Here are the tray and trigger I found: https://www.amazon.com/dp/B07PQPN8Q9?psc=1&ref_=cm_sw_r_cp_ud_ct_WK3788XJR91B6HWMAEPZ https://www.amazon.com/dp/B0CP558GV3?psc=1&ref_=cm_sw_r_cp_ud_ct_WK3788XJR91B6HWMAEPZ_1 I like the price and size of the tray (it is 11" long rather than 13" of the higher-end trays), but I'm a little concerned that it will be adequate to mount the trigger as it only has 2 1/4-20 tapped holes.

Totaly with Tim

Can totally understand Nemrod’s view. Loads of pics are spoilt be inelegant diver poses. Images with divers need care and direction . But that’s where the beauty of the partners relationship kicks in. You work with your partner creating an image which he/she loves, which was created together and can get you some cracking images. “You spend quality time together on the dive”….. you still get it in the neck after, but that’s love, right?

Very good information, if we can't trust a brand new port...Anyway, at the time that I was about to buy a Seafrogs aluminum housing I contacted directly the manufacturer and after a misunderstanding I though I was going to be scammed. Finally they told me that the aluminium section and the plastic section are totally different, with different engineers based in different factories and in different cities. I was told they share the name but nothing else.

see the video above from Sean Elliot, 21700 its the battery chemistry/format. The SEAL model batteries looks like are built-in Type-C charging: 1: Unscrew the cover and charge the flashlight with the charging from an appropriate USB source, the switch indicator light is red；When the battery is full, the switch LED turns blue. 2: Before diving, please check whether the charging port is tightened to prevent water ingress. https://www.letondive.com/pages/download-product-manual?srsltid=AfmBOopyKZo5nsHQrTU25WJdebJy8Ne0rYXs7oq-0HrnwnjhJwAd-xi_

Thanks for your feedback, Dave. It's really neat and tidy now, and the port is only larger where it's absolutely unobtrusive, so the case still sits nice and flat. The unit weighs around 190g with the buoyancy aids. I could probably reduce that a bit more, but so far the balance between stability and robustness is perfect. With the right material, the body could be filled even more, and I might even be able to get more than 500g of buoyancy. Tino

There are many lovely women and handsome men (of which I am not) but frankly I do not find the human form underwater especially compelling. Here and there, yes, but mostly, I do not want divers in my pictures. Yes, divers can add a human interest element. I am mostly not interested in other humans, I seen them before, mostly too much ;). I know I said same ocean buddy but I DO take into account my buddies skills as to exactly how far I will let them away from me and I do keep and eye on their location. Fortunately I am not a macro guy. I feel for the macro folks who need to take some time on a small critter. All my buddies 🤗 :

99% ???? I'm right ? 🤣

…. Guess how many pictures I delete 🫡

That sounds interesting, don't get the "built in" but "21700" concept, would be interested to see a teardown video if this is somehow user-serviceable.

I have a salted line housing - I'm not sure if this is the same as a sea frogs aluminium or not its not bad. Its cheap relative to nauticam and it is quite small compared to my old ikelite 35mm nikon housing Controls are ok but a bit fiddly flooded twice. once a dodgy new macro port from the manufacturer that just leaked once when I was distracted by an alluring dive instructor and forgot to check that I had closed it properly I tend to buy quite cheap cameras to put in it (second hand 6x alphas) and I'm reasonably pleased with it Ideally I would like a full frame with a larger viewfinder but its not a deal breaker

good advice thank you. I'm not sure persuading her to get that close the the sharks will be straightforwards but including her as a model would probably be quite an attractive idea to her. Then of course some images will have to be deleted because I have got her wrong side or her eyes are closed 😊
