A full-featured and durable waterproof housing for Canon EOS 77D, EOS 9000D DSLR cameras. Suitable for scuba, snorkel, surf, pool, and any application in or around the water. This housing requires the addition of a compatible DL Lens Port for waterproof operation. Lens Port not included. View the DLM/C Lens Port Chart... Lens Ports At the heart of any great image is good glass; At the centre of the housing is the Dry Lock (DL) Port System. "Dry Lock" refers to the placement of the o-ring on the outside of the port mount. This improves visibility and reduces the chances of water dropping onto your precious camera sensor. DL ports are the lightest on the market, yet robust and capable of standing up to rough surf. Attachment is quick and secure. A system of extensions can accommodate a huge variety of lenses with ease. Most popular zoom lenses and select lens focus rings can be engaged using a simple yet effective gearing system that puts adjustment right at your fingertips. A large, soft-touch lobed knob on the side of the housing makes fine-tuned adjustments a breeze. Zoom and focus gears differ depending on which lens you are using. All are lightweight and affordable. Refer to the DL System Port Chart to choose the correct gear. Zoom gears are sold separately. Legacy Four Lock Port Compatibility Due to differences in mount diameter and zoom engagement, DL and FL system ports cannot be used interchangeably. The DL port mount may be removed and replaced with old style Port Locks for FL Port System (Set of 4) #5509.04 for legacy users with standard or modular ports from Ikelite's Four Lock system. This modification will prevent the use of newer DL ports. Re-installation of the DL port base will require the housing to be returned to Ikelite or an Authorized Dealer and may incur additional service charges. The housing cannot be converted back and forth repeatedly. There are significant advantages to upgrading your lens ports. If you're shooting an 8" diameter dome, you'll also save almost .907g (2 pounds) by switching to the DL version. Vacuum System The included vacuum valve allows you to pressurize the housing to check for leaks before putting your expensive equipment in the water. Use of the vacuum valve requires a compatible Vacuum Pump with Gauge # 47011, sold separately. There is no greater assurance than being able to see your camera and o-ring seal through the back of the housing. Our signature open-groove design suspends the rear o-ring in a natural position that is easier to maintain and more reliable than forcing the o-ring into a channel. Once the housing is closed you can see the o-ring form a solid, waterproof seal. TTL Exposure This housing supports your choice of shooting manual strobes or adding TTL electronics depending on your application. The flash bulkhead has been moved to the top of the case for improved cord routing and reduced strain. You can enjoy the fastest and most accurate TTL exposure on the market by adding the DL5 DS Link Canon TTL Converter and CT1 TTL Hotshoe Kit # 46075 and a compatible Ikelite DS strobe. Exposure compensation can be used added or subtracted in the camera. Reliable locking connectors between the hotshoe and bulkhead make it easy to install the optional TTL electronics or carry back up parts when travelling to remote locations. Controls and Set-Up Shutter and AF-ON levers stand out with super sensitive and natural feeling curved levers.  Both controls can be extended using the optional Shutter Trigger Extension # 4077.95 for more comfortable use when using a right-hand quick release handle. All push-button controls are machined and hard anodized aluminium to reduce weight and resist salt build-up. The back of the housing is laser engraved with control symbols that will never fade or fall off. The camera mount is front-loading for easy installation and removal. A small mounting plate attaches to the bottom of the camera and secures in the front of the housing. The camera mounting plate does not need to be removed from the camera for surface use or when changing the battery or memory cards. The mounting plate features a 1/4-20 threaded mount on the bottom so that it can be attached to a tripod on the surface. Viewfinders The included Super-Eye Viewfinder provides an enhanced view of the camera's optical viewfinder when viewed through a dive mask. The viewfinder removes quickly and easily for the attachment of an optional Straight Magnified Viewfinder # 6890 or 45° Magnified Viewfinder (Type 2) # 6891.2. The angle of a 45º viewfinder is more ergonomic when shooting underwater plus it provides a larger and brighter view than the standard Super-Eye. Handling & Travel The housing, tray, and handles have been optimized to reduce weight while maintaining strength and durability. The Right-Hand Quick Release Handle # 4077.02 (sold separately) can be added or removed depending on your needs. The precision-machined aluminium base features 1/4-20 tripod mounting sockets and additional mounting locations for future accessories. The base and handle can be quickly removed when breaking down your system for travel. A 1/4-20 threaded mounting point is located front and centre on the housing above the lens port mount. This mount can be used to attach lightweight accessories like a focus light or GoPro camera. If you're shooting with two strobes or lighting arms, then an Aluminium Top Handle # 4080.08 can be added to carry to and from the dive site. The rigid aluminium version provides additional mounting points for lighting and accessories. Construction Ikelite's new ABS-PC blend front is stronger than its clear counterpart, provides improved contrast and visibility, and keeps your camera running cooler in the sun. Every housing is made in the USA, individually inspected for fit, and water pressure tested to 60m (200 feet).
