I shot only video and reviewing the footage my plain camera mic grabs all noise generated by me operating the camera. I clearly hear my clip banging on the housing, backfocus lever press, zoom or focus gear rotation and even shutter and other buttons. -
Point taken! So, can we rephrase that a larger Depth of Field helps us, mere mortals, achieve decent focus? 😇

Yes it can be a significant advantage for macro photography, as it allows you to fill the frame with smaller subjects without needing to get physically closer but then we should debate about specific lens... For uw video I'm still convinced that cropped sensors have an edge on FF sensor but again, the ideal choice depends heavily on your specific needs, shooting style, and budget.

I'll give a shot among two lenses, both 1:1 but one is FF and the other is M43 A 1:1 magnification ratio signifies that the lens can project an image of a subject onto the camera's sensor that is the exact same size as the subject itself in real life. For instance, if you're photographing a 10mm-long insect, at 1:1 magnification, the image of that insect onto the sensor will also be 10mm long. This definition remains constant regardless of the sensor size. A full-frame sensor has dimensions of approximately 36mm x 24mm. A Micro Four Thirds sensor is smaller, at about 17.3mm x 13mm. On your full-frame camera, the 10mm projection of the insect will take up a relatively small portion of the large 36mm x 24mm sensor. On your M43 camera, that same 10mm projection will fill a much larger percentage of the smaller 17.3mm x 13mm sensor. When you view the images from both cameras on a screen or in a print of the same size, the insect from the M43 camera will appear significantly larger. This is because the smaller sensor has effectively "zoomed in" on the center of the image circle projected by the lens. While the fundamental optical magnification of both lenses is identical at 1:1, the smaller M43 sensor results in a tighter field of view, making your subject appear twice as large in the final photograph compared to the full-frame setup at the same 1:1 magnification setting. Of course, with a 50Mp FF camera you can crop the image and you can throw away my reasoning 😁

It's easy to say "videolight"! But what about two Keldan 8X with ambient LEDs, aren't you going to throw those in too?

Tell us more about the logistic. Ho many lights? On the bottom?

Welcome to the forum! That's a serious upgrade, Focusing on video and documentary work aligns well with that gear. Nowadays, documentaries that tell direct experiences of citizen science are very popular. Both from the researcher's side and the participating citizen's side. Perhaps your previous university experiences are an excellent starting point for finding subjects. I've tried to document several citizen science projects myself. The problem is finding funding, and if you want to do professional work, you need money. Sometimes it's the university projects themselves that have dedicated funds for communication. Feel free to share specific questions or details about the type of projects you're pursuing. We look forward to seeing your work.

Hello Sabrina! A warm welcome to our community! I'm sure you'll love the Z8 just as much as your trusty D850. Feel free to share your diving experiences and photos anytime you like.

Sea Frogs has officially released its new Z6-III aluminum alloy housing, designed specifically for Nikon’s latest Z6 III full-frame mirrorless camera. Continuing Sea Frogs’ tradition of precision craftsmanship and technological innovation, this new housing offers reliable underwater photography support for both professional photographers and diving enthusiasts—further pushing the boundaries of creative exploration. Key Features: Professional Protection and User-Friendly Design Aviation-Grade Aluminum Alloy Construction The Z6-III housing is built from high-strength aluminum alloy, striking a balance between lightweight design and exceptional compressive strength. It performs reliably in demanding environments, supporting underwater use at depths of up to 100 meters. Its excellent corrosion resistance makes it ideal for use in seawater, freshwater, and extreme outdoor conditions. Optimized Button Layout Tailored to match the Nikon Z6 III’s control logic, all buttons and dials are engineered with specialized technology to ensure seamless operation underwater—just like on land. Modular Expansion Interface Includes a top-mounted M28 interface reserved for external monitor connectivity. Optical-Grade Glass Ports and Safety Design Equipped with ultra-clear, optical-grade dome and flat ports designed to minimize distortion and chromatic aberration, ensuring maximum image sharpness and color fidelity underwater. The O-ring sealing system and pressure balance valve effectively prevent deformation due to leakage or pressure differentials, ensuring long-term durability and performance. -
Reading the two threads on the topic, it makes me think that the improvements also depend on the lens used. Am I wrong?
-
Opening post updated with new Seafrog monitor. I got a reply directly from Seafrog with product data. Moreover the housing comes with a M24 or M28 bulkhead.
-
The housing seems to be very well made, and I also see a lot of empty space for the battery, which might actually be a good thing. I'll try to find out more and update the table.

Hi Christian, Welcome back to our new home. You have plenty of time to be a good waterpixeler 😝
-
I found one used (as new) here in Italy at 295€ or best offer. Maybe after the Alex's video they will choose to produce them again
-
For video, I don't notice any issues with the edges, but it's a shame it's so expensive just to even try it out. Edit: according to Alex, it's something more related to the Pana 30mm lens.

I just read a thought-provoking article on EOSHD about the current state of camera prices.

Which curved port would be suitable for our Pana-Leica 45mm?

While I completely agree that a good battery charger is essential for ensuring a long life for rechargeable batteries, over the years I've charged batteries with the most absurd junk and never had anything like this happen. IMHO, I think it's more likely a batch of defective batteries. If I were you, I'd try to contact Eneloop/Panasonic and report what happened.

I reopen this old message because I discovered that Isotta added a mysterious "lens Holder" to their action cam accessories page with no explanation, but from the photos it seems a Inon/AOI adapter 🕵♀️ ISOTTA - Underwater housingsGoPro lens holder

Yesterday, their website only had the photo and the page was empty. There wasn't even a name. Today it's appeared, but the rest is still blank. As soon as they publish the specs, I'll update the list.

Hi Raptor Welcome to the forum! It's great you making the move over here! I'm sure you will find a lot of well known names. We're always happy to see new members, especially those who prefer wide-angle 🤣

Original post updated with product links, prices, and weights

Thanks for the data. You confirmed it is another brick 🙂 How are you finding it? What's your opinion? What's your use case? Regarding Kraken monitors, they kindly wrote me that both the 5" and 7" went through an upgrade. Specifically the V2 versions of the monitor haven't changed in terms of function, but they do use 21700 batteries now instead of the big battery block so they are lighter weight and much slimmer than the previous versions. Hence: The 5” V2 monitor is 1680g on land and 260g underwater The 7” V2 monitor is 1795g on land and 230g underwater. Table updated!
