Is the Samsung Galaxy S26 Ultra a good option for underwater photography?
The Samsung Galaxy S26 Ultra is an excellent device for underwater photography in natural light. Its high-performance sensor and advanced image processing deliver impressive results. The key is to choose the right underwater housing and master the basics of underwater photography.
What waterproof case is suitable for the Samsung Galaxy S26 Ultra for use while diving?
For the Samsung Galaxy S26 Ultra, the Divevolk SeaTouch 4 Max is a good option. Make sure you have the Platinum version for newer Ultra models. Other brands also offer dedicated housings, so be sure to check compatibility.
Does the Samsung Galaxy S26 Ultra capture RAW images while underwater?
Yes, the Samsung Galaxy S26 Ultra supports the RAW format through its RAW Expert mode. This is a key feature for post-production and for getting the most out of your underwater images. It gives you great flexibility to adjust exposure and white balance.
What is the expected battery life for a full day of diving, consisting of three dives, when using a Samsung Galaxy S26 Ultra?
With careful battery management and by avoiding intensive use outside of the water, the Samsung Galaxy S26 Ultra can last for a day of three dives. Its battery capacity is good, but the cold environment of the water can affect its performance. It's a good idea to bring a power bank for extra security.
Should an anti-fog treatment be used with this device?
Yes, absolutely. Due to its aluminum housing, the risk of condensation in cold water (below 15 degrees Celsius) is significant. Using an anti-fog treatment- such as a silica gel packet or anti-fog inserts- inside the housing is mandatory before each dive.
How can I quickly transfer my photos and videos from this device?
This device features a fast USB-C port (USB 3.0 or 3.2). You can transfer your large RAW files or video clips in just seconds (100 to 800 MB/s) directly to an external compatible SSD or a computer.

Ideal User Profile: This camera is perfect for divers who want a versatile device capable of producing beautiful underwater images without being weighed down by bulky equipment. The user is willing to invest in a good housing and learn the basics of RAW post-processing. This is a great choice for those who seek simplicity without sacrificing image quality.
Analysis by Component
B1 - Optics
The optics of the S26 Ultra are excellent. The images are sharp, with good detail. Chromatic aberration is well controlled, even in challenging underwater lighting conditions. The versatility of the lenses is a major advantage. You can easily switch from wide-angle to telephoto with excellent results. The key feature is the ability to capture fine details of marine subjects.
For more information: The S26 Ultra incorporates high-quality lenses, optimized for clarity and reduced reflections. The software effectively compensates for distortions.
B2 - RAW
The Expert RAW mode is the real highlight here. It allows you to capture RAW files with extended color depth and dynamic range. This gives you the freedom to correct white balance and exposure in post-processing. Without RAW, underwater photography is much more limited. The S26 Ultra represents a significant leap forward compared to previous models that did not offer this capability.To delve deeper: The S26 Ultra, with its Snapdragon 8 Elite Gen 2 processor, handles RAW Expert mode. This is an improvement over the S25/S25+ models, which lacked native Log recording, or the S23/S23 Ultra, which had more limited RAW processing capabilities.
B3 - Storage
The internal storage is generous. This is important because RAW files are large. Data transfer is fast thanks to the USB 3.2 (10 Gbps) and Wi-Fi 7. You won't waste time emptying your memory card after each dive. Quick Share is very effective for wireless transfers, which greatly simplifies the on-site workflow.
To delve deeper: The S26 Ultra benefits from USB 3.2 (10 Gbps) and Wi-Fi 7, just like the S24 Ultra. This is an advantage over the S25/S25+ and S23/S23 Ultra models, which only had USB 3.2 (5 Gbps) and Wi-Fi 6E.
B4 - Thermal Management
The titanium frame of the S26 Ultra is a plus. It helps with heat dissipation. When diving, the water temperature also helps, but a good frame reduces the risk of overheating and condensation inside the housing. This is a common issue with aluminum phones like the S23 or S23 Ultra, where the risk of condensation was high.To delve deeper: The S26 Ultra uses a titanium frame, just like the S24 Ultra. The S23, S23 Ultra, S25, and S25+ models are made of aluminum, which can cause condensation problems in cold environments.
B5 - Battery
Battery life is a major strength. The S26 Ultra's battery can last for multiple dives. For a day of three dives, with reasonable usage, you should be fine. However, the coldness of the water can slightly reduce battery life. It's always wise to have an external battery pack on hand, especially if you're filming a lot.
To delve deeper: The battery capacity of the S26 Ultra is optimized by the Snapdragon 8 Elite Gen 2, offering better energy efficiency.
Before each dive session, remember to check your external battery. Use our portable battery comparator tool to choose the power bank that's right for your housing and your desired battery life.
B6 - Autofocus
The autofocus is fast and accurate. Underwater, where light is often dim and subjects are moving, this is crucial. The S26 Ultra locks onto subjects well, even in challenging conditions. This reduces the number of blurry photos and increases your chances of capturing the perfect moment. The responsiveness is excellent.To delve deeper: The Snapdragon 8 Elite Gen 2 processor in the S26 Ultra enhances autofocus performance, especially in low-light conditions and when photographing moving subjects.
B7 - Housing
Choosing the right housing is crucial for underwater photography. For the S26 Ultra, you need a compatible housing. The Divevolk SeaTouch 4 Max is a popular option, but make sure you have the Platinum version for the latest Ultra models. A good housing guarantees waterproofing and access to the phone's functions. Without a reliable housing, your S26 Ultra will never reach the bottom.
To delve deeper: The Divevolk SeaTouch 4 Max is compatible with all models, but the Platinum version is necessary for the latest Ultra models to ensure optimal compatibility and a good seal.
HousingsThe housing is the most important investment. Without it, no diving. The Divevolk SeaTouch 4 Max is a top-of-the-line option. Always verify the exact compatibility with the S26 Ultra. Other brands offer housings, but the quality and ergonomics vary. Don't compromise on this item. It's the safety of your phone and the key to successful underwater photos.
Field Workflow
The S26 Ultra simplifies the workflow. The fast transfer of photos via USB 3.2 or Quick Share is a major advantage. You can edit your RAW files directly on your phone using dedicated apps. This allows for quick sharing of your photos. Prepare your phone before the dive: charge it, clear the memory if needed, and check the waterproof seal of the housing.
Important Considerations
Color balance management underwater remains a challenge for all smartphones. Even with RAW files, you will often need to make corrections in post-production. Natural light varies greatly. Learn to anticipate these variations. Avoid strong backlighting. Condensation can still be a problem if the phone gets too hot before being placed in the cold housing.
PriceThe Samsung Galaxy S26 Ultra is a high-end smartphone. Its price is significant. Add to that the cost of a good underwater housing. It's an investment. But for a device that combines a daily phone with a powerful underwater photography tool, the value proposition can be interesting for some divers. Consider the entire ecosystem.
Our Verdict
The Samsung Galaxy S26 Ultra is an excellent choice for underwater photography in natural light. It doesn't replace a dedicated camera with a large sensor, but it comes dangerously close for informed amateur use. The RAW Expert mode and fast connectivity are major advantages. If you're looking for a versatile and high-performing dive companion, the S26 Ultra, when properly equipped with an appropriate housing, is a compelling option. It will allow you to capture stunning memories without breaking the bank on heavy photography equipment. It's a reliable tool for exploring the underwater world.
