There was something unusual about the way Sony announced the Xperia 1 VIII on May 13, 2026. No large-scale conference or keynote presentation. Just a simple press release, technical specifications published without excessive marketing hype, and a delayed release date of June 26 for Europe.

For someone who has been following the evolution of camera phones for years, this is a recognizable approach. Sony isn't trying to convince the masses. The Xperia 1 VIII is designed for a specific segment of photographers who know what they want and are capable of reading a technical specification sheet from beginning to end.

This review aims to answer a specific question: Is this device worth anything underwater, in natural light, under real-world diving conditions?

This device is for: The Android scuba photographer who wants the equivalent of an Alpha in their pocket, with Zeiss color science and a RAW format that's usable without artificial post-processing.

This device is not ideal for: Someone who wants to go diving tomorrow with a ready-to-use housing. The accessory ecosystem is still being developed.

The Xperia 1 VIII features three 48-megapixel effective sensors, a consistency that Sony had not yet dared to implement in previous generations.

The main sensor (24 mm, f/1.9) uses a 1/1.35-inch Exmor T with OIS. The periscope telephoto lens (70 mm, f/2.8) uses a 1/1.56-inch Exmor RS with OIS as well. The ultra-wide angle lens (16 mm, f/2.0) shares the same 1/1.56-inch format.Underwater, the main sensor is primarily used in approximately 80% of situations. The Exmor T 1/1.35-inch sensor performs well in filtered light, and the Zeiss T* coating effectively reduces unwanted reflections - this was a major frustration with previous smartphones when shooting against bright underwater backgrounds.

For more information Score B1: 3.7/5 - Details of the 9 criteria: - Sensor size (1/1.35"): 2.5/5 - below the Sony Alpha inch sensor - Resolution (48 MP): 4.0/5 - above the threshold of 47 MP - Aperture f/1.9: 3.5/5 - between the f/1.8 and f/2.0 thresholds - Native ISO (estimated clean 3200): 4.0/5 - consistent with the Snapdragon 8 Elite Gen 5 generation - Stabilization (OIS + EIS 5 axes): 4.0/5 - Telephoto minimum focus distance (15 cm minimum): 3.0/5 - a step back compared to the VII (4 cm macro) - Flare/ghosting (Zeiss T*): 4.0/5 - anti-reflection coating confirmed, not tested underwater - Burst mode (30 fps AF/AE, buffer not documented): 4.0/5 - Shutter lag (estimated <50 ms, not measured independently): 4.0/5

A point to note: Sony has increased the minimum focus distance of the telephoto lens from 4 cm (Xperia 1 VII) to 15 cm on the VIII. This is a significant step back for those who used the telephoto lens for close-up macro photography. The main sensor likely compensates at distances below 10 cm, but this data has not been officially documented at this time.

RAW DNG files are natively available in the Photo Pro app, across all three sensors. There's no need for a third-party application to shoot in RAW format. Sony has extended its multi-frame RAW processing pipeline to all three lenses, which expands dynamic range in HDR and reduces noise in low light.

The Zeiss color science is certified - not just a marketing partnership, but a documented calibration with Zeiss. The combination of RAW DNG + Zeiss T* optics + S-Cinetone for mobile provides rendering that doesn't try to "improve" the image by default. What the sensor captures is what the file contains. Underwater, in natural light, this is exactly what we are looking for.

For more details Score B2: 4.6/5 - Breakdown of the 6 criteria: - Native DNG RAW: 5.0/5 - Bit depth (estimated at 12 bits, not officially documented): 4.0/5 - Manual white balance in Kelvin for video (Pro Video mode): 5.0/5 - Maximum video codec (H.265 10-bit HDR in 4K 120fps, 10-bit not confirmed in standard mode): 3.5/5 - Third-party app (Blackmagic Camera Android since v1.4 - Xperia support confirmed): 5.0/5 - Color science (Zeiss certified + S-Cinetone for mobile): 5.0/5 Note: The availability of Blackmagic Camera for Android on Xperia is confirmed since version 1.4 on the Xperia 1 models. Official compatibility with the VIII is not yet listed as of June 30, 2026, please verify upon activation.The lockable Kelvin white balance in Pro Video mode is a key feature that is often underestimated. Underwater, where the color temperature changes at each depth level, being able to set the Kelvin value before entering the water and not touching it during the entire dive fundamentally improves the color consistency of a series of images.

With a 48 MP RAW DNG file, a photo weighs between 25 and 40 MB depending on the scene. During a 50-minute dive, it's not uncommon to take 300 to 500 shots. The math is simple.

The Xperia 1 VIII offers 256 GB, 512 GB or 1 TB of internal UFS storage, with a microSD slot that accepts up to 2 TB. In practice, the 512 GB version with a 256 GB microSD card covers several days of an intensive diving trip without having to empty the phone between dives.

On-site transfer is possible via OTG (USB 3.2, 5 Gbps), which allows you to connect a portable SSD between dives and transfer 50 GB in less than 10 minutes. This is logistics that works in real conditions.

To learn more Score B3: 4.3/5 - Details of the 3 criteria: - Capacity (up to 1 TB internal + microSD 2 TB): 5.0/5 - USB 3.2 Gen 1 connector (theoretical 5 Gbps): 4.0/5 - On-site OTG transfer + SSD, data rate > 500 MB/min: 4.0/5

The chassis is made of aluminum. When the device transitions from an ambient temperature of 22 degrees Celsius to water at 12 degrees (typical of the Mediterranean Sea in November or the North Atlantic in summer), the thermal difference can create potential condensation on the inner glass of the housing. This phenomenon is documented for all aluminum smartphones with high thermal conductivity.

In tropical waters above 25 degrees, the risk is significantly lower and the situation approaches normal operation.

For more information Score B4: 2.8/5 - Details of the 2 criteria: - Condensation risk (aluminum, reference to tropical water): 2.5/5 - Shock resistance (IP65/IP68 + Gorilla Glass Victus 2, without MIL-STD-810 certification): 3.0/5 In cold water (<15°C), the condensation score drops to 1.5/5. Divers in cold waters (North Sea, Brittany, Canada, North Pacific) should factor this risk into their housing protocol.

Sony has certified the device with IP65/IP68 ratings and features Gorilla Glass Victus 2 on the front. This provides good protection against surface impacts and handling on boats. However, resistance to impacts related to vibrations within the housing is not covered by a MIL-STD-810 certification.

To ensure your smartphone fits securely and compare interior volume, make sure to check if your model's dimensions fit in this housing.

Three 50-minute dives with 4K 60fps video recording and RAW photo bursts should leave approximately 40% to 50% of the battery remaining. Under normal conditions, the phone can last a full day of diving without needing a recharge.

For more information B5 Score: 3.0/5 - Details of the two criteria: - Capacity x chemistry (5,000 mAh, standard Li-Ion, efficient 3nm): 4.0/5 - Lifespan (not officially documented, Battery Care and Adaptive Charging features present): 2.0/5 Standard lithium-ion chemistry, without silicon carbide, theoretically limits the number of charge cycles to around 300 to 500 before a 20% loss in capacity. Sony does not publish a guaranteed lifespan for the battery cell.

The Xperia Adaptive Charging feature and Battery Care mode extend the battery's lifespan over time. For a device costing €1,500 and intended to last for several seasons, this aspect should be re-evaluated after 18 months of use.

The autofocus system of the Xperia 1 VIII is directly inherited from Sony's Alpha cameras.The three sensors feature a bi-directional phase detection autofocus (PDAF) system. The AF/AE calculation runs at 60 times per second, with a burst rate of 30 frames per second in continuous AF/AE mode. Real-time Eye AF (for humans and animals) works on all three lenses. And the Real-time Tracking feature stays locked onto the subject even when shooting video.

This level of autofocus performance is particularly relevant underwater for two reasons: fish don't pose, and visibility changes with every dive. A system that recalculates 60 times per second has a statistically higher chance of locking onto a grouper swimming by at 1.2 meters in 8 meters of visibility than any contrast-based AF system.

For more details Score B6: 4.5/5 - Multi-directional PDAF on all 3 sensors - 60 AF/AE calculations per second (measurable in real-world conditions) - Human + animal Eye AF + Real-time Tracking - Focus Peaking expected in Pro Photo/Pro Video mode (standard for Xperia 1 since the VI) - No LiDAR (iPhone Pro only), no infrared laser detected - PDAF with AI without particles: not specifically documented for the VIII The score would be 5.0/5 with confirmation of Focus Peaking and documentation of the anti-particle AI.A key consideration for diving in murky water: the Xperia 1 VIII does not have LiDAR (a physical distance measurement technology, available only on iPhone Pro models). In waters with a lot of particles, the phase detection autofocus (PDAF) can struggle with suspended matter. Manual focus using the Pro Photo mode remains a viable alternative - and it works well on Xperia 1 phones in general.

This is an area that requires patience as of June 2026.

The Xperia 1 VIII began shipping on June 26, 2026. As of the publication of this review, no dedicated hard housings have been confirmed by major brands (Divevolk, Ikelite, Nauticam, AOI).

Divevolk has released SeaTouch adapters for the Xperia 1 III, IV, V, and VII models. This history is encouraging: an adapter for the VIII is very likely to be available in the coming weeks. The SeaTouch 4 Max (certified to 60 meters, with full touchscreen access via a gel membrane) is the solution that best suits the profile of the Xperia 1 VIII.

For shallow dives while you wait (snorkeling, freediving, coastal diving at depths less than 10 meters), a universal housing adapted to the dimensions of 162 x 74 x 8.3 mm may work, subject to verification with the manufacturer.

A helpful resource for understanding how to choose: our comprehensive guide to waterproof housings.

Specific points to watch out for: - Cold water: include a desiccant packet in the housing and check for condensation after each dive. - Minimum focus: The 15 cm distance of the telephoto lens is a drawback compared to the Xperia 1 VII for close-up macro photography. Prefer the main sensor for subjects closer than 15 cm. - Blackmagic Camera Android: confirm explicit compatibility with model VIII before relying on it while traveling.

Comparison with other tested smartphones: - vs OPPO Find X9: The Xperia 1 VIII outperforms the OPPO in autofocus and Sony Alpha maturity. The OPPO had a Divevolk housing confirmed from its release. - vs Google Pixel 10 Pro: The Pixel excels in ease of use and automatic computational processing, while the Xperia offers more manual control and RAW color fidelity. - vs Samsung Galaxy: Samsung's Ocean Mode is convenient for snorkeling, but the Xperia's RAW + Zeiss system is in a different league.

The problem is timing. A device released on June 26, 2026, doesn't yet have a complete ecosystem of accessories available. A smartphone without a certified underwater housing remains just a smartphone. For deep dives, you will need to wait a few more weeks.

My recommendation: if you are already using Android, if you are comfortable with RAW workflows, and if you are willing to wait for the Divevolk housing, the Xperia 1 VIII is definitely worth considering. If you want to dive next August with a complete and documented setup, come back in two months - the review will be updated as soon as a dedicated housing becomes available.
