Hi Rob, Welcome back online and great to have you here! My son is also a big fan of mermaids and tailed sea creatures. Nice collection of mermaid tails here... 🧜🏽♂️ I don't think it's practically possible as things stand. It would require a very technical intervention from the forum administrator, and he haven't been very present lately 😇 -
Ciao Lidas Welcome aboard!

Loud and clear!

Doomsday Device! @Alex_Mustard What is it?

Hi Reefy Welcome aboard!

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?
