Looking to purchase a Sea & Sea 77mm internal correction lens. If anybody has one that they're looking to offload, please let me know!

I can confirm that the Samyang 12mm AF f2.0 lens works flawlessly behind the seafrogs 6" dome port designed for the Sony 10-18mm with any of the a6xxx cameras. Especially with the glass dome port option, the corner sharpness is really excellent, and the whole package is quite inexpensive. It's awesome for reefscapes but definitely not the most versatile system out there in terms of focal lengths available. The 100º FOV is great IMO though.

Looking for an AOI housing for an OM System OM-5, so either the UH-EM5iii or UH-OM5 model will work!

Price drop to $350!

SOLD

Selling a used AOI / Backscatter Octo print housing for Olympus E-PL9 and E-PL10 housings. It's an awesome housing in great shape. It was factory refurbished in 2022 (had a faulty seal around a button) and has been used on <5 dives since. Comes with housing, standard lens port for 14-42mm EZ lens, vacuum pump, flash trigger, rear viewfinder shade, extra o-rings, and shutter extension. Retail is $650, asking $400 OBO. PM me with offers!

Selling a barely used Nauticam mini flash trigger. It's been used a couple times on my Sony A7C but works with most Sony cameras. Check out the product listing on Nauticam's website here. Retails for a bit over $300 USD. I'm looking to get $200 plus shipping (should be minimal) for it.

Price drop! This kit is still available and I'm lowering the asking price to $6800. Willing to consider offers for specific parts of the kit as well. PM me!

I frequently use a Sony a6600 camera in a SeaFrogs housing with a Samyang 12mm f2 lens. It just so happens that it is nearly perfectly optically matched to the Seafrogs 6" glass dome. It gives you a 100º FOV with almost zero distortion, and the corner sharpness is really surprisingly good for such a relatively inexpensive setup, even shooting at fairly wide apertures (f4 is quite usable). Focusses right to the glass so it's great for CFWA. If you like reefscapes but don't love the fisheye look, it's a really solid setup. It also has the benefit of being excellent for underwater photogrammetry (which is what I use it for primarily).

Selling a full-fledged Nikon D850 kit with Sea & Sea Housing and 3 lenses in overall great shape. This setup has been used by me mostly for underwater photogrammetry for coral reef research at the Perry Institute for Marine Science in The Bahamas. We're trimming down our equipment inventory and this bad boy needs to go. I'm looking to sell this all as a kit, but am willing to consider offers on specific items (PM me). Here's what the kit includes: Main Items - Nikon D850 Camera Body (Excellent condition - only ever used in a housing) - Nikkor 16-35mm f4 VR lens (Like new condition - with caps/hood/pouch) - Nikkor 35mm f1.8 lens (Like new condition - with caps/hood/pouch) - Nikkor 60mm f2.8 Macro (Never used mint condition - with caps/hood/pouch) - Sea & Sea MDX-D850 Housing (Good condition - some minor scuffs on the back but nothing severe) - Sea & Sea Compact NX Dome Port (Good condition - one minor scratch that could be buffed out - it's acrylic) - Sea & Sea 8-Inch Acrylic Dome Port (Fair condition - one area of surface abrasion that would be easy to buff out - see photos) - Sea & Sea DX Macro Port 52 (Never used, mint condition) - 2x Sea & Sea 40L Extension Rings (Excellent condition) - Sea & Sea 20L Extension Ring (Excellent condition) - Sea & Sea YS Converter/N1 (installed in housing) - Pelican Air 1615 Travel Case (fair condition, fits all items easily with room to spare) Accessories - Extra Nikon EN-EL15 Battery (2 genuine total) - 2x Watson EN-EL15 Spare Batteries - Sony 256GB XQD Card - 2x XQD USB3.0 Card Readers - Nikonos Sync Cable + Bulkhead - Sea & Sea Zoom Gear for 16-35mm lens All told, the retail price for this kit is north of $14k... I'm asking $7200 OBO for all of it. Please PM me with offers or for additional information or photos. This is an excellent underwater package that has a whole lot of years of life left in it - I hope it can find a good home!

Apparently the AF-D compatible adapter will be available very soon: https://www.sonyalpharumors.com/new-product-release-monster-adapter-la-fe2/ The new adapter should open up the option to use the Sigma 15mm and Nikon 16mm fisheyes on Sony FF bodies, which could be helpful for some folks.

Ian, thanks for the kind introduction! Sadly, our oceans are changing faster than we can document and understand effectively... Even being in my 20s, the changes I've seen in the Caribbean just during my lifetime of diving have been dramatic and truly scary. The research I do is mainly in The Bahamas and the changes to the benthic community even in just the past 5 years have been crazy, due mainly to the combined influences of Stony Coral Tissue Loss Disease (which some of you may be familiar with, others not - it's a disease affecting about half of Caribbean hard coral species with extremely high mortality rates, threatening to cause local and/or total extinctions of corals like pillar and some brain corals) and coral bleaching. This past summer, the warming influence of climate change combined with the effects of El Niño to produce extremely warm ocean temperatures in Florida and across the Caribbean, and the bleaching we observed this August/September in The Bahamas was unlike anything we've seen. My main research involves using underwater photogrammetry to create "digital replicas" of sections of reef that we monitor repeatedly to track changes happening over time. Attached is a side-by-side example of some of the time-series data we collect (demonstrating severe bleaching) and a photo from the Exumas showing some extensive bleaching on a very high coral-cover reef. Across much of The Bahamas and Florida, the ocean heatwave killed a gigantic portion (90-100% in many areas) of Staghorn coral in particular- formerly one of the most important coral species for adding structural complexity and habitat quality for shallow reefs in The Caribbean that is now critically endangered and on the cusp of extinction in many regions. The one other thing I'll say is that most of us working in the coral research world haven't given up hope - there are good people working on thermal tolerance in corals and many restoration projects working to nurse dead and dying reefs back to health. More broadly, those of us who have seen the changes happening under the waves need to use our voices to speak up and advocate for policy change that protects our oceans and our planet. Climate change may be the biggest direct threat, but is just one of many including overfishing, pollution, disease, dredging, etc. The majority of people aren't able to see under the ocean, but as underwater photographers, we have a unique role in sharing what we witness underwater with the world to help bring awareness and attention. Keep fighting the good fight!

Hi all, I'm Will, a coral ecologist and photographer working for the Perry Institute for Marine Science in The Bahamas and a PhD student at Arizona State University. I've been an underwater photographer for about 15 years (since I was 12!) and my job and research mostly involves underwater photogrammetry and aerial remote sensing for coral reef monitoring. For my research and personal underwater photography, I primarily use Sony full frame cameras and adapted Nikonos lenses (15mm primarily, but also the 20mm, 80mm, and the Sea&Sea 12mm fisheye). In terms of pure rectilinear image quality, usefulness of large apertures, and size, there's nothing that can compete with the Nikonos 15mm once you get it properly adapted on a digital underwater camera! If anybody has questions about underwater photogrammetry or getting old Nikonos manual focus lenses to work properly on Sony/Nauticam systems, don't hesitate to reach out! Best, Will
