Inon X-2 Canon R5 Mk II Underwater Housing
The Inon X-2 Canon R5 Mark II underwater housing is built to solve a very specific problem we see with high-resolution mirrorless bodies underwater: how to maintain reliable TTL exposure, rapid burst shooting, and precise manual focus control without turning the rig into a bulky science project. After working hands-on with the X-2 system, it’s clear this housing is engineered around optical strobe accuracy, sealing confidence, and fast-paced still photography—not general-purpose modularity.
At the core of this canon r5 II underwater housing is Inon’s ultra-accurate, multi-functional built-in TTL Converter, included as a standard feature. Unlike third-party triggers, this converter is designed specifically around INON strobe flash protocols, enabling stable, repeatable TTL exposure, rear-curtain sync, and high-speed continuous shooting up to 12 fps with strobes. For shooters who rely on TTL but still want direct control, flash output can be adjusted directly from the camera—something our customers consistently appreciate when working with long strobe arms or backlighting techniques.
The housing itself is compact and lightweight thanks to an ultra-precision cast aluminum body, and it incorporates a standard Vacuum Leak Sensor that verifies sealing in just three minutes. Add in the newly developed S-MRS magnetic port system for ultra-precise manual focus and the optional Quick Shoe System for fast orientation changes, and this underwater housing is clearly aimed at experienced photographers who want speed, accuracy, and predictability underwater.
- Best for: Advanced still photographers using INON strobes who want reliable TTL, burst shooting, and precise manual focus control.
- Not for: Shooters expecting electrical sync, cross-brand strobe compatibility, or a video-first control layout.
- Built-in INON-specific TTL Converter supports TTL, rear-curtain sync, and up to 12 fps continuous strobe firing.
- Flash output and strobe behavior can be adjusted directly from the camera menu.
- Standard Vacuum Leak Sensor confirms sealing in ~3 minutes and monitors pressure during the dive.
Key Features:
Ultra-accurate multi-functional built-in "TTL Converter"
The "TTL Converter" equipped as a standard feature, triggers INON strobe optically to enjoy fully automatic TTL. Exclusively developed for INON strobe based on its flash protocol to optimize its performance for underwater use
Strobe manual power is directly adjustable from camera
Adjusting the manual power of INON strobes is incredibly convenient, as it can be done directly from your camera. You have the flexibility to choose power settings ranging from 1/64 to FULL, with convenient 1/3EV increments. This feature proves especially valuable when your strobe is positioned at a distance, such as on a long strobe arm, or when capturing images using the backlit technique.
12 shots/sec. continuous strobe firing
The TTL Converter offers complete compatibility with [High speed continuous][High speed continuous+] mode, enabling exceptionally precise TTL shooting for continuous capture powered by a capacitor6. The INON TTL Converter delivers over 100,000 flash triggers using just two CR2032 coin batteries, guaranteeing extended performance and reliability.
