RDX-550D specifications

The Sea & Sea RDX-550D is a high-performance underwater housing designed specifically for the Canon EOS 550D (Rebel T2i) digital SLR camera, creating an ideal setup for underwater photography enthusiasts and professionals alike. With the promise of durability, user-friendliness, and excellent functionality, the RDX-550D serves as a reliable companion for divers who wish to capture stunning images and videos beneath the waves.

One of the main features of the RDX-550D is its construction from robust polycarbonate, providing an excellent balance of lightweight characteristics and durability. This material ensures that the housing is resilient against the often harsh conditions of underwater environments, while still allowing for ease of handling on land. Additionally, the housing is designed to be waterproof up to a depth of 60 meters (197 feet), making it suitable for a range of diving scenarios from recreational to more technical dives.

The housing offers full access to all camera controls, including the on/off switch, shutter button, and mode dial, allowing photographers to operate their camera with precision while submerged. The ergonomic design ensures that users can easily reach these controls even while wearing gloves, an essential feature for underwater photography.

One of the notable technologies integrated into the RDX-550D is the dual fiber-optic cable ports. These ports allow for the attachment of external strobe lights, significantly enhancing the lighting quality of underwater images. The benefit of using external strobes cannot be overstated, as they provide the necessary illumination to overcome the challenges posed by underwater light conditions, such as limited visibility and color absorption at greater depths.

Additionally, the housing features an easy-to-read window for the LCD screen, ensuring that divers can monitor their camera settings and compositions without having to surface. This window is complemented by an anti-fogging system that prevents moisture from clouding the view, allowing users to maintain clarity during their dives.

The RDX-550D also accommodates a variety of accessories, including wide-angle and macro lens ports, enabling photographers to expand their creativity and versatility underwater. Compatibility with port systems allows users to easily switch between different lens options, tailoring their equipment to suit specific shooting scenarios.

In summary, the Sea & Sea RDX-550D is an exceptional underwater housing that combines durability, accessibility, and advanced features to enhance the underwater photography experience. Its robust construction, ergonomic design, and compatibility with external lighting and lenses make it a valuable tool for anyone serious about capturing the beauty and wonder of the underwater world.
