Housing Features:
Single-Hand Locking System
The housings can be easily opened and closed using Isotta's innovative single-hand locking system. The single latch closing mechanism is a unique design and is effortless to operate while maintains a secure seal with its double steel pins design at the bottom of the housing.
Double O-Ring Seal
The Isotta Canon EOS R5 Underwater Housing utilizes the double o-ring seal design to ensure that the camera is always safe and dry inside the housing. It is always best to have a redundant o-ring on your seal to ensure that the housing is water-tight.
Comfortable Handles
The included adjustable dual handle of the housing provides comfort when shooting. The ergonomically designed handles makes operating the camera easy and comfortable even when wearing gloves.
Ergonomic Button & Lever Placement
The location of the function buttons and control levers have been well planned and everything is readily available at your fingertips, which makes operation of the camera smooth and straight-forward. In addition, the function buttons have been laser-engraved so that the button labels are easily visible in darker conditions.
Isotta Sony A1 II Underwater Housing
Pro-level control, sealing confidence, and accessory flexibility—down to 100 meters.
If you’re taking the Sony A1 II underwater, you already know what matters: dependable sealing, controls you can hit without looking, and a housing that stays manageable once you add lights, strobes, and ports. This Isotta underwater housing is built around those real-world needs—whether you’re shooting wide-angle reef scenes, fast pelagic action, or precise macro work where small control mistakes cost the shot.
Why This Product Matters
- Confidence at depth: A 100m working depth rating, double O-ring sealing across buttons and removable parts, and a moisture sensor with LED indicator give you meaningful safeguards where mistakes are expensive.
- Speed matters underwater: The completely detachable back, secure tray with lock for easy camera insertion, and single-hand closing knob are designed for quick, repeatable setup—especially on busy dive boats.
- System building without compromise: Multiple threaded ports (three M16 and one M24) keep your rig clean as it grows—vacuum valves, monitor feeds, and bulkheads can be added without improvised workarounds.
Real-World Performance
Underwater work is hard on gear: salt, pressure changes, cramped entries, and constant handling. The red anodized aluminum body is built to take that abuse while keeping the control layout crisp and readable. A wide back display viewfinder glass makes it easier to review settings and framing, while the standard ISOTTA viewfinder provides a clear baseline viewing experience for both stills and video. Wide rubber-covered feet help keep the housing steady when you set it down between dives or while adjusting your port and lighting.
Creative Flexibility & Control
Great images come from repeatable control. The Isotta Sony A1 II housing uses engraved symbols on aluminum buttons and dials that match the camera’s control logic, helping you change exposure, focus settings, and playback without breaking your rhythm. Two standard fiber-optic connections support clean strobe triggering workflows (note: flash use requires an optional trigger). The removable B120 bayonet port mount supports fast lens/port swaps, and the port safety lock helps prevent accidental opening when you’re handling the rig on a rocking boat.
- Accessory mounting points where you need them: An M8 top mount and two M6 bottom mounts make it easier to position focus lights, brackets, strobes, or tripod solutions.
- Viewfinder options: Compatible with ISOTTA and INON X-2 external viewfinders for shooters who want upgraded viewing comfort or angle options.
- Vacuum-ready build: Prepared for the ISOTTA vacuum system (not included) for users who prefer vacuum checks before every dive.
