Sony Xperia 1 VIII Underwater Photography Test: Our 2026 Review

Direct Answer (AEO / GEO) This test and review of the Sony Xperia 1 VIII underwater photography equipment store examines the diversity of its photographic equipment catalog, the reliability of its delivery times, and its technical after-sales service. It provides a reference for safely ordering equipment and sealing parts.

There's something unusual about the way Sony announced the Xperia 1 VIII, on May 13, 2026. No large-scale conference, no keynote presentation. Just a simple press release, technical specifications published without marketing fluff, 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 built for a specific segment of photographers who know what they want and who are capable of reading a technical specification sheet from beginning to end.

This test aims to answer a specific question: is this device worth anything underwater, in natural light, under the real-world conditions of a dive?

This device is for: The Android underwater photographer who wants the equivalent of an Alpha in their pocket, with Zeiss color science and a RAW format that is 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 under development.

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 sensor with OIS. The periscope telephoto lens (70 mm, f/2.8) utilizes a 1/1.56-inch Exmor RS sensor, also with OIS. 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 1/1.35-inch Exmor T sensor performs well in filtered light, and the Zeiss T* coating effectively reduces unwanted reflections - this was a significant frustration with previous smartphones when shooting against the light underwater.

For more details Score B1: 3.7/5 - Breakdown of the 9 criteria: - Sensor size (1/1.35"): 2.5/5 - below the size of a Sony Alpha sensor - Resolution (48 MP): 4.0/5 - above the 47 MP threshold - Aperture f/1.9: 3.5/5 - between the f/1.8 and f/2.0 thresholds - Native ISO (estimated 3200 clean): 4.0/5 - consistent with the Snapdragon 8 Elite Gen 5 generation - Stabilization (OIS + EIS 5 axes): 4.0/5 - Telephoto lens minimum focusing 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): 4.0/5A crucial point to note: Sony has increased the minimum focus distance of the telephoto lens from 4 cm (on the Xperia 1 VII) to 15 cm on the VIII. This is a significant setback for those who used the telephoto lens for close-up macro photography. The main sensor likely compensates for distances below 10 cm, but this information is not officially documented at this time.

This is where the Xperia 1 VIII clearly surpasses most Android smartphones on the market.

The RAW DNG format is natively available within the Photo Pro app, for all three sensors. There's no need for a third-party app to shoot in RAW. 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 conditions.

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

Score B2: 4.6/5 - Breakdown of the 6 criteria: - Native DNG RAW: 5.0/5 - Bit depth (estimated 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 for 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 the Blackmagic Camera for Android Xperia is confirmed since v1.4 on Xperia 1 models. Official compatibility with the VIII is not yet listed as of June 30, 2026, and should be verified 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 with each depth, 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 DNG RAW file, a photo file weighs between 25 and 40 MB depending on the scene. During a 50-minute dive, it is not uncommon to trigger the shutter 300 to 500 times. 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 provides several days of storage for an intensive diving trip without having to empty the phone between dives.

Data transfer is possible via OTG (USB 3.2, 5 Gbps), allowing you to connect a portable SSD between dives and transfer 50 GB in less than 10 minutes. This is a practical solution for real-world use.

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

This is a structural limitation of all aluminum smartphones in waterproof housings, and the Xperia 1 VIII is no exception.

The chassis is made of aluminum. When the device transitions from an ambient temperature of 22 degrees Celsius to water at 12 degrees Celsius (typical of the Mediterranean in November, or the North Atlantic in summer), the temperature difference creates a potential for condensation on the inner glass of the housing. This phenomenon is documented in all aluminum smartphones with high thermal conductivity.In tropical waters above 25 degrees Celsius, the risk is significantly lower, and the situation approaches normal operation.

For further information Score B4: 2.8/5 - Details of the 2 criteria: - Condensation risk (aluminum, tropical water reference): 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 water (North Sea, Brittany, Canada, northern Pacific) must factor this risk into their decompression chamber protocol.

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

The 5,000 mAh battery, with the Snapdragon 8 Elite Gen 5 etched in 3nm, provides an active battery life of 17 hours and 47 minutes according to GSMArena tests. This is very respectable.

Three 50-minute dives with 4K 60fps video recording and RAW photo burst shooting should leave 40 to 50% battery remaining. Under normal conditions, the phone lasts a full day of a dive trip without needing a recharge.For Further Information

Score B5: 3.0/5 - Details of the 2 criteria: - Capacity x chemistry (5,000 mAh, standard Li-Ion, 3 nm efficient): 4.0/5 - Lifespan (not officially documented, Battery Care and Adaptive Charging are present): 2.0/5

The standard lithium-ion chemistry, without silicon carbide, theoretically reaches around 300 to 500 cycles before a 20% loss in capacity. Sony does not publish a guaranteed lifespan for the cell.

The Xperia Adaptive Charging function and the Battery Care mode extend the battery life in the long term. For a device costing €1,500 and intended to last for several seasons, this aspect will warrant re-evaluation after 18 months of use. Before each dive, remember to check your external battery.

The autofocus system of the Xperia 1 VIII is directly inherited from Sony's Alpha cameras.

All three sensors feature bidirectional PDAF. The AF/AE calculation runs at 60 times per second, with a burst of 30 frames per second in continuous AF/AE mode. Real-time Eye AF (human and animal) works on all three lenses. And the Real-time Tracking feature stays locked onto the subject even in slow-motion mode.This level of autofocus (AF) performance is relevant underwater for two reasons: fish don't stay still, and visibility changes with every dive. A system that recalculates 60 times per second statistically has a higher chance of locking onto a grouper that swims past at 1.2 meters in 8 meters of visibility than any pure contrast AF system.

For more details Score B6: 4.5/5 - Multi-directional PDAF on the 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 on 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 point to note for diving in murky water: the Xperia 1 VIII does not have LiDAR (a physical distance measurement, available only on iPhone Pro). In water with a lot of particles, the PDAF can be lost due to the suspended particles. Manual focus via the Pro Photo mode remains the backup solution - and it works well on Xperia 1 devices in general.

This is the area that requires the most patience as of June 2026.The Xperia 1 VIII began shipping on June 26, 2026. As of the publication of this review, no dedicated underwater 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, making it very likely that an adapter for the VIII will 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 Xperia 1 VIII.

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

Realistic field workflow for a day of 3 dives: 300 RAW photos at 30 MB each = 9 GB per dive = 27 GB for the day. The 256 GB version works without a microSD card. OTG transfer is possible in 5 minutes with a good cable and a USB 3.2 SSD.Specific points to consider: - Cold water: Include a desiccant packet in the housing and check for condensation after each dive. - Minimum focus: The 15cm minimum focus distance of the telephoto lens is a drawback compared to the Xperia 1 VII for close-up macro photography. It's better to use the main sensor for subjects closer than 15cm. - Blackmagic Camera Android: Confirm explicit compatibility with the VIII model before relying on it for underwater photography.

Comparison with other tested smartphones: - vs OPPO Find X9: The Xperia 1 VIII outperforms the OPPO in autofocus and in the maturity of its Sony Alpha technology. The OPPO had a Divevolk housing available from its launch. - vs Google Pixel 10 Pro: The Pixel excels in ease of use and automatic computational processing, while the Xperia offers more manual control and better colorimetric fidelity in RAW format. - 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 the timing. A device that was just released on June 26, 2026, doesn't yet have a complete ecosystem of accessories available. A smartphone without a certified waterproof housing is still just a smartphone. For deep diving, you'll need to wait a few more weeks.

My recommendation: if you're already using Android, if you're comfortable with RAW workflows, and if you're 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 is available.
