Aquatica 550D Housing

FOR CANON 550D/Rebel T2i

The Aquatica 550D/T2i housing is a working proof of our ongoing commitment to get high quality products available not only rapidly to the users, but with a reasonable pricing as well - Aquatica is proudly introducing its latest addition for the new Canon T2i / 550D camera.

With an impressive 18MP APS-C CMOS sensor and 1080p HD video recording with easy manual controls, this camera/housing combination is the ultimate affordable refinement of underwater imaging at the moment. TTL strobe exposure is now a breeze with the Optical Fiber strobe connectors. You can take full advantage of the newer strobe lighting technologies available today while retaining the options of classic Nikonos and Ikelite bulkhead connectors available to the user.

This form fitting and light weight housing is machined from solid aluminum on our new 5 axis machining center. A sophisticated instrument that enables us to reduce weight and size like never before. The 550D housing is treated and anodized to military specification, then coated with a powder coating and baked for a robust weather and wear resistant external finish. The 550D housing maybe light but will still benefit from the same 90m/300 ft.+ depth rating that has set us apart from our competitors for so long.

Introduced with the Aquatica 550D housing is a new type of retractable focus/zoom gear rack and lens release lever. Pulling out these cleverly designed controls clears the path for smooth installation and removal of the camera/lens assembly even when a zoom or focus gear is attached to the lens. Battery, card or lens replacement now becomes a simple straightforward task to do.

The Aquatica 550D housing features easy access to the vital video function controls while retaining its ease of operation for still imaging. All vital controls for both imaging modes have been moved to easily accessible and comfortable locations on the housing. Of course, it also benefits from the same time-proven mounting bayonet and will accept all our existing accessories and ports, including our tack sharp Megadome, the new Mini Dome, low profile macro port, Aqua View finder and remote control cord. We now present you a tool up to the task of fulfilling the needs of the most demanding underwater imaging individual.


Optical Fiber Strobe Connectors: Options include Optical ports for both Sea & Sea ® or INON ® type connectors, as well traditional methods of connecting strobes via the Nikonos ® or Ikelite ® standard connectors. In essence, it makes this housing the most flexible in the industry as far as connectivity to underwater strobes.

Internal camera flash access: A push button on the housing is provided to release the flash in the up position and a lever to shut it down. This allows the user to quickly shutdown the internal flash for ambient light images and easily returns to flash photography at the push of a button.

Bayonet Port: Positive four point bayonet mounting and a locking mechanism leaves no doubt that your ports are secure, in place and water tight. The bayonet system dome, macro ports and extension rings offers the fastest and most comprehensive access to the lenses for rapid changing without having to remove the camera from the housing. This housing allows use of lenses from a 10mm/180 degrees fisheye lens to a 200mm macro lens. Teleconverter port extensions are also available.

Menus: Buttons have been angled 20 degrees and extended when needed for better ergonomics. Knobs are now grooved and knurled for optimum operation even when wearing thick gloves.

Hydrophone: Available as an accessory and easily mounted via one of the provided accessory bulkhead mounting holes.

Controls: Fingertip access to all camera menus and video controls includes On-Off, Live View mode, Record On/Off, ISO lever, Exposure Mode, bracketing, Meter positioning and focus control, AF activation and lock access via a single easy access lever. Access to all menu features include review, enlarge and delete, histogram and internal SLR preferences.

Lens Release: (NEW) A retractable lever is provided for easy lens changing through the front port with camera installed.

Retractable Focus / Zoom control knob: (NEW) A retractable mechanism now allows the gear rack to be pulled out of the way, making easy work of inserting and removing the camera when a lens with a gear is attached to it.

Remote Control Grip: Available as an accessory and easily mounted via one of the provided accessory bulkhead mounting holes

Viewing Eye Piece: The most critical aspect of underwater SLR photography is the viewing system. In this aspect our housing uses a viewfinder that shows the biggest and brightest image possible in full frame viewing to your eye. An accessory Aqua View Finder is also available giving the user unparalleled viewing of the camera's viewfinder for sharp focusing and exact composition.

The recommended servicing procedures of the products are outlined in the manuals supplied with the product. The outside of the housings and the accessories should be rinsed in fresh water after every dive.

The handles should be removed after use otherwise if they remain attached to the housing for any length of time they may bind to the housing and be extremely difficult to remove. We suggest that the main O rings be lubricated regularly and all of the O rings be checked annually.
