OPPO's partnership with Hasselblad has steadily elevated smartphone photography into professional territory. With the OPPO Find X9 series, that partnership reaches its most capable generation yet—and when you pair it with a DIVEVOLK SeaTouch 4 Max underwater housing, the result is a smartphone underwater photography system that punches far above its weight class.
This guide breaks down the Find X9 series' core advantages for underwater shooting, its specialized features, and how the DIVEVOLK housing unlocks the full potential from the shallows to 60 meters deep.
Hasselblad Imaging System: Color Accuracy That Matters Underwater
Underwater photography's greatest enemy is color distortion. As depth increases, red wavelengths vanish first, turning warm, vibrant reef scenes into flat blue-green images. The OPPO Find X9 Pro's Hasselblad Master imaging system addresses this from the ground up.
The primary camera features a 50MP Ultra XDR sensor with an F/1.5 aperture and OIS—an exceptionally wide aperture that maximizes light intake in the dimmer underwater environment. The ultra-wide lens matches at 50MP with autofocus, delivering sharp edge-to-edge results for reef panoramas and fish school compositions.
The critical differentiator is OPPO and Hasselblad's 4th-generation color reproduction technology. This system fuses data from the imaging sensor and a multi-spectral sensor through an upgraded Ultra-class Danxia color restoration lens. The result: accurate color reproduction even in underwater's challenging multi-color-temperature environments. When you photograph a coral reef teeming with orange clownfish, purple sea fans, and green staghorn coral, the Find X9 reproduces what your eyes actually saw—not a blue-tinted approximation.
Full Focal Range: From 10cm Macro to 120x Zoom
The underwater world rewards both extremes of focal length. Macro reveals the hidden—nudibranch gills, coral polyp tentacles, cleaner shrimp at work. Telephoto captures the spectacular—cruising mantas, patrolling sharks, distant turtle silhouettes. The Find X9 series covers the full spectrum.
Find X9 Pro
The Pro model packs a 200MP Hasselblad periscope telephoto with a massive 1/1.4-inch sensor. It delivers 3x optical zoom and 13.2x lossless zoom, powered by OPPO's proprietary LUMO image engine that maintains clarity even in light-starved underwater conditions. This same telephoto lens doubles as a 10cm macro shooter—letting you switch instantly between a wide reef shot and an extreme close-up of a nudibranch without changing any hardware.
Find X9 Ultra
For maximum reach, the Ultra features the industry's only dual periscope telephoto system: a 200MP medium telephoto at 3x optical zoom plus a dedicated super-telephoto at 10x optical zoom (230mm equivalent), extensible to 120x digital. This means you can photograph a reef shark from a safe, respectful distance and still fill the frame with detail—a real advantage for responsible wildlife photography. Maintaining distance from marine life isn't just good practice; it's essential for protecting both the animals and yourself, as organizations like Mission Blue consistently emphasize.
Underwater Shooting Techniques for the Find X9
While the Find X9 series doesn't include a labeled "Underwater Mode" like some competitors, its IP66/IP68/IP69 triple waterproof rating and rich feature set provide everything needed for excellent underwater results. Here are the key techniques:
Leveraging the Camera Control Button
The Find X9 Pro carries a dedicated camera control button on the lower right side. Double-click to launch the camera; slide your finger to zoom; press to shoot. This physical control is invaluable underwater, where touchscreens can be unpredictable due to water contact. Inside a DIVEVOLK SeaTouch 4 Max housing with full touchscreen capability, you get the best of both worlds—physical button reliability and full screen control.
Exposure Compensation for Depth
Water absorbs light rapidly. A simple +1 EV exposure compensation when shooting portraits underwater helps counteract light loss and restores natural skin tones. For split-level shots at the surface, try turning the phone upside down (lens facing up) to capture dramatic water-surface refractions.
Post-Dive Water Drainage
After surfacing, a 3-second long-press of the power button activates the speaker vibration drainage function, expelling residual water droplets from the speaker grille—a thoughtful detail that prevents fogging on subsequent shots.
Hasselblad Master Mode: Professional Control Underwater
For photographers who want full manual control, the Find X9's Master Mode provides a professional parameter panel with quick switching between 0.6x ultra-wide, 1x primary, and 2x/3x/6x telephoto focal lengths.
Underwater, manual exposure control is essential:
- Overexposed surface highlights? Lower EV compensation to recover detail in bright areas
- Deep-water darkness? Increase ISO (keep below 400 to manage noise) and slow the shutter to gather more light
- Color cast? Manually adjust white balance, or use DIVEVOLK's red filter accessory for physical correction
Master Mode Pro adds contrast, saturation, and sharpness controls—giving you granular creative control before you even open an editing app. For underwater video shooters, the Find X9 Pro supports 4K 120fps Dolby Vision recording and is ACES certified with 4K 10-bit Log output, preserving maximum dynamic range for professional color grading in post-production.
Hasselblad Native Film Modes: Cinematic Underwater Looks
In April 2026, OPPO and Hasselblad launched Native Film modes—a feature that goes deeper than traditional filters. Instead of applying color overlays in post-processing, Native Film integrates directly into the image processing pipeline, using raw light data to create authentic film-stock aesthetics while preserving full detail and dynamic range.
The Find X9 offers nine film styles across four series. For underwater photography, consider:
- CC or NC Classic Negative: Warm, vintage tones that beautifully complement coral reef colors
- RDP3 Positive Film: Enhances golden sunset light penetrating the water surface—ideal for shallow dives during golden hour
- 800T Night Negative: Maintains clean, noise-free results in deep-water low-light conditions
Each style gives your underwater images a distinct emotional character straight out of the camera—no post-processing required.
8K Super-Clear Photos Across All Focal Lengths
A common frustration in underwater photography: the shot looks great on a small screen, but falls apart when you zoom in. The Find X9 series solves this with Hasselblad 8K Super-Clear photos—enabled by default in photo mode across ultra-wide, primary, and periscope telephoto lenses.
Every shot captures enough resolution to crop aggressively and still retain sharp detail. Missed the composition on a passing sea turtle? Crop in post and the image holds up. This feature is especially valuable underwater, where you often can't reposition for a second attempt.
4K Live Photos: Never Miss the Moment
Marine life doesn't pose. A clownfish darts into its anemone in a fraction of a second. An octopus shifts color in a heartbeat. The Find X9's 4K Live Photo feature captures a brief video clip around every still image at full 4K resolution. After the dive, scrub through the clip frame by frame and select the perfect moment as your final image—no more missed shots due to shutter timing.
Pairing with DIVEVOLK SeaTouch 4 Max: The Complete System
The OPPO Find X9's IP69 rating handles splashes and brief submersion, but real underwater photography—reef diving, freediving, snorkeling at depth—demands purpose-built protection. The DIVEVOLK SeaTouch 4 Max provides exactly that:
- 60m/196ft depth rating for recreational and technical diving
- Full touchscreen operation to access every Find X9 feature—including Master Mode parameter adjustments—while submerged
- Swappable phone adapters so one housing works with your Find X9 today and your next phone tomorrow
- A full accessory ecosystem: video lights, wide-angle lenses, macro lenses, red filters, handles, and external shutters
The combination of Hasselblad's color science and DIVEVOLK's depth-rated housing creates a smartphone underwater photography system that genuinely competes with entry-level dedicated underwater cameras—at a fraction of the size, weight, and cost.
