At Deep Sensations Freediving, our Underwater Photographers @curtistredway and @brodiewmedia are always eager to test out new gear. Recently, Seafrogs sent Curtis a new housing, as the old one he and Brodie had shared had done its years.
Upgrading to the Seafrogs Salted Line housing for our Sony A7III with the 16-35mm f/4 Zeiss has been a game-changer. Compared to previous Seafrogs housings, this model feels like a significant step up in both build quality and functionality.
Build & Design
The first thing we noticed is how much more robust and high-quality this housing feels. The metal clips add a layer of confidence, eliminating any concerns about durability in high-pressure environments. The overall construction is solid yet lightweight, making it easier to handle both in and out of the water.
Usability & Controls


One of the standout features is the ergonomic control system. Unlike older models, this housing allows full control of all camera dials, including aperture, shutter speed, and ISO, without any awkward adjustments. The tactile response of the dials makes on-the-fly changes smooth and intuitive, which is a massive plus for both photography and video work.
Viewfinder & Optical Clarity

The enhanced viewfinder is another major improvement. Compared to the previous model they have expanded the display on the back plate allowing for clear vision of the camera screen, making composition and focus adjustments effortless. Paired with the 16-35mm f/4 Zeiss, the clarity and sharpness of underwater images are exceptional, capturing everything from vibrant coral reefs to fast-moving marine life.
Performance in the Field
We've already put this housing through its paces in Port Kembla, Byron Bay and Ningaloo Reef, and the results speak for themselves. The housing has performed flawlessly, providing the confidence to shoot in dynamic and the unpredictable underwater conditions experienced on the East Coast of Australia.
Compared to my previous Seafrogs housing, I have found the dials and buttons work seamlessly, allowing my to adjust the settings on the fly to shoot for the subject or situation.
Final Thoughts
If you're upgrading from an older Seafrogs model, the Salted Line housing is well worth it. The improved durability, superior ergonomics, and full camera control make it an excellent choice for serious underwater photographers and videographers. Whether you're shooting shallow reef scenes or deep wreck dives, this housing delivers reliability, usability, and outstanding image quality.
The Pros:
✔ Great price compared to other underwater housings
✔ More robust & high-quality build
✔ Metal clips for added security
✔ Full camera control with all dials accessible
✔ Great viewfinder visibility
✔ Performs well in varied underwater environments
The Cons:
✔ The vacuum test system, much like its predecessor, is cumbersome to use. Manually pumping over 100 times just to get a reading is time-consuming and inefficient. Additionally, after testing the vacuum, you must remove the gauge and reinsert the vacuum port plug, creating an opportunity for user error and potential sealing issues. An external reader would be a much more convenient and user-friendly solution.
For those looking to get the most out of their Sony A7III underwater, this housing is an absolute win. Can't wait to keep pushing its limits in more dive sites around Australia!
Who is This Camera Good For?
This camera is a great camera for beginner underwater photographers, and those who are on a budget. Whilst this underwater housing is in the lower price bracket, it doesn't feel like a budget housing in the slightest. You will get the most bang for your buck!
