New housing for Canon’s entry-level APS-C camera features a fixed port designed to accommodate the RF-S 18–45mm f/4.5–6.3 kit lens
Showcased at the ADEX dive show in Singapore in April, the new AOI housing for the Canon EOS R50 has now been released. Like the popular EF-S-mount EOS M50 Mark II before it, the RF-mount EOS R50 is an entry-level cropped-sensor powerhouse packed with great features for serious shooters: 24MP sensor with dual pixel AF, 15fps burst shooting (electronic shutter), and 4K/30p 10-bit video with no crop.
AOI’s UH-R50 housing features a fixed port designed specifically for the RF-S 18–45mm f/4.5–6.3 IS STM—the standard zoom that is available in a kit with the R50. This arrangement means users can start shooting a variety of subjects right out of the box, while the smallest and largest subjects can be tackled by mounting macro or wide-angle wet lenses onto the port’s standard 67mm thread. AOI offers a variety of high-quality wet lenses, including the UWL-09PRO for wide angle and UCL-09PRO for close-ups.
Coming as standard with AOI’s Vacuum Analysis & Wet Detection System (VWS), the housing offers dual fiber-optic bulkheads for hooking up strobes such as AOI’s own UCS-Q1 flash (updated 2027 edition), which offers a new slave TTL mode for automatic flash exposure. Triggering is via the R50’s pop-up flash, so you don’t have to purchase a separate trigger. The housing is compatible with MDS (Modular System), the company’s highly configurable arm and tray solution.
Shipping now, the AOI UH-R50 housing costs $700 and is available in both black and white finishes.
PRESS RELEASE
AOI Unveils the UH-R50: Making Passion Possible for the Next Generation of Underwater Creators
AOI Ltd. is proud to announce the UH-R50, a breakthrough underwater housing for the Canon R50 designed to bridge the gap between casual snapshots and advanced cinematography. Built on AOI’s core brand philosophy of Passion Possible, the UH-R50 is engineered to democratize high-fidelity imaging, ensuring that the transition from a smartphone or action camera to a powerful mirrorless system is intuitive, cost-effective, and seamless.
The “Level-Up” Choice: Advanced Power, Mobile Simplicity
The UH-R50 is the definitive “Level-Up” for aficionados who have outgrown the limitations of small-sensor devices. By moving to the R50’s larger APS-C sensor, users can finally capture the true colors, low-light clarity, and cinematic depth of field that smartphones and action cameras cannot replicate. It provides a pro-tier look while maintaining a nimble, “grab-and-go” lifestyle. With a dry weight of just 495 grams for the Canon EOS R50 camera and 1,433 grams for the UH-R50 housing, this combination is among the lightest mirrorless systems on the market today, ensuring effortless travel and exceptional underwater agility.
Native Vertical Intelligence for the Social-First Creator
In an era where short-form content drives the global conversation, the UH-R50 is designed to take full advantage of the Canon EOS R50’s native orientation intelligence. The camera automatically identifies when it is shooting in a vertical format and tags the footage accordingly.
To complement this feature, the UH-R50 is fully compatible with AOI’s MDS (Modular System). The MDS is a highly configurable, almost bespoke arm and tray solution that allows creators to build a rig tailored to their specific needs. By utilizing the MDS, users can configure their ergonomics for stable, vertical-friendly handling, making it the ultimate tool for high-resolution TikToks, Reels, and YouTube Shorts.
The Specialized Fixed-Port Advantage
While AOI remains committed to its industry-leading interchangeable port systems for professional vocations, the UH-R50 introduces a specialized fixed-port design tailored for experts who prioritize nimble, efficient workflows. This integrated approach offers distinct advantages for the rapid-deployment creator:
- Streamlined Security: The fixed-port design offers a “Set-and-Forget” experience. By reducing the number of user-serviceable seals, the UH-R50 provides a highly reliable, low-maintenance profile ideal for travel.
- Factory-Tuned Precision: The port is factory-aligned to the specific optics of the Canon R50 kit lens, ensuring edge-to-edge sharpness and perfect optical performance out of the box.
- External Versatility: Featuring a standard 67mm thread, the fixed port remains a versatile platform. Creators can switch between wide-angle and macro wet-optics mid-dive using AOI’s world-class optics, such as the UWL-09PRO, keeping the camera sensor sealed and safe at all times.
Performance Without the Premium: High-Fidelity at a High-Value
The combination of the Canon EOS R50, its versatile kit lens, and the AOI UH-R50 housing represents one of the most accessible avenues in the industry to produce high-fidelity underwater content. By optimizing the system around a fixed-port architecture, AOI has removed the “entry tax” typically associated with mirrorless underwater photography.
- Upgraded Peace of Mind: The housing features AOI’s VWS (Vacuum Analysis & Wet Detection System) as a standard feature. This internal system actively monitors internal vacuum pressure and detects moisture before a single drop hits the camera sensor, providing definitive confidence before and during every dive.
- Seamless Integration: The newly upgraded UCS-Q1 can be used with the Canon EOS R50 inside AOI’s newly launched UH-R50 underwater housing. Creators using this new setup can rely on effortless, automated lighting that perfectly complements the R50 system’s compact footprint.
For approximately the same investment as a decent smartphone and a specialized housing, creators gain access to an advanced 24.2MP sensor and world-class 4K video. This setup offers a higher-fidelity standard that empowers aficionados to produce gallery-grade photos and cinematic videos without the premium price barrier.
Availability
The AOI UH-R50 will be available through authorized AOl dealers and select digital marketplaces in June 2026.
