Ikelite 69540 200DLM/B Olympus / OM-1 Housing
The Ikelite 200DLM/B Underwater Housing is the perfect companion allowing the use of the OM System (Olympus) OM-1 mirrorless micro four-thirds camera in or around the water for scuba, snorkelling, surf, pool, or any adventure.
This housing requires the addition of a compatible DLM Lens Port for waterproof operation. Lens Port is not included.
OM System OM-1
Not to be confused with the 50-year-old Olympus film camera, the OM-1 is the flagship micro four-thirds mirrorless model from the new OM System brand and perhaps the last camera to carry the Olympus name upfront. No matter what you call it, the OM-1 is a powerful mid-range camera and a pleasure to use underwater. The 20.4-megapixel camera features 5-axis in-body image stabilization (IBIS), 4K/60p Ultra HD and 1080/240p video capture, and a decent battery rating of 520 shots per charge (CIPA).
While you’ll need a housing to take it underwater, the OM-1 does boast solid weatherproofing along with an IP53 rating for dust- and splash resistance.

Ergonomics and handling
Good ergonomics are critical when you need to concentrate on composition, focus, and proper exposure. Large, curved control levers put the most important controls right where you need them: shutter and autofocus (via the AEL/AFL button). This combination allows you to shoot with or without back button focus, an advanced technique that is useful for tack sharp focus of super macro and fast-moving subjects. Each lever can be extended using the optional Shutter Trigger Extension # 4077.95 for perfect spacing when using a right-hand handle.
All rotating controls are operated intuitively via premium soft-touch knobs. Stainless steel, direct-drive rotating controls are virtually fail-safe and user-serviceable and adjustable in a pinch.
Camera buttons are accessible by smooth action, hard-anodized aluminium push buttons for reliable performance and easy maintenance. These controls are clearly labelled by laser engraving on the back of the housing that never fades or falls off.
Two 1/4-20 threaded mounting points are included on the bottom of the housing for the simple, rotation-free attachment of a tray and handle system. Handles provide improved ergonomics underwater and are the foundation for your lighting mounts. The Tray with Dual Quick Release Handles # 9523.64 is the most popular choice for both handling and attachment of accessories.
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.
The unique rear seal design prevents accidental twisting or stretching of the o-ring for simple and confident assembly. Ikelite has eliminated the need for an o-ring groove or channel which can trap sand, dirt, or debris. Two double-passivated stainless steel locking lid snaps are simple to use and virtually unbreakable. The clear back allows you to see the o-ring form a solid, watertight seal as it closes.
A spare 1/2-20 threaded accessory port is provided on the side of the housing for easily installation of the optional Vacuum Kit # 47012. A vacuum kit allows you to draw a vacuum on the housing to check for leaks prior to entering the water. Drawing a vacuum on the system also provides extra security at the surface of the water, especially important when using the housing in rough surf.
The camera’s large, super-bright LCD screen is viewable edge-to-edge through the back of the housing. An included optical viewfinder window blocks ambient light to improve the viewing of the camera’s electronic viewfinder (EVF) for both image composition and review.
Get the brightest and sharpest view of the camera’s OLED EVF by adding an optional Magnified Viewfinder. The Supereye removes quickly and easily for the attachment of a Straight Enhanced Magnified Viewfinder # 6890.2 or 45° Magnified Viewfinder (Type 3) # 6891.3.
Light is absorbed as it travels through even short distances underwater, making colours appear dull or monochromatic. To preserve the natural colours of your subject, it’s important to stay within arm’s reach—no more than 1m (3-4 feet) away. For the best results, we recommend adding an external flash or high-powered constant-on light if you’ll be diving regularly below 3m (15ft).
You can enjoy the fastest and most accurate TTL exposure on the market by adding the Ikelite DL3 DS Link TTL Converter and Hotshoe Kit # 46032 and a compatible Ikelite DS strobe. Rear-curtain flash synchronization is supported. 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 TTL hotshoe or carry backup parts when travelling to remote locations.
This camera does not feature a built-in flash for the triggering of fibre optic strobes.
A bright constant-on video light can be used instead of or in addition to a flash. A constant-on light is not as bright as a strobe flash. Constant-on lights do provide added versatility because they can be used for focus assist and for improved colours when shooting video.
There is a simple rule that brighter is better underwater. A high-quality lighting system can produce professional quality results.
It couldn’t be simpler to change ports than this system—just press the port on and tighten three thumb screws. Feel positive reinforcement that the port is secure with simple parts you can trust in a remote location.
This housing accepts ports from Ikelite’s DLM Port System to accommodate a selection of the best zoom, macro, and wide-angle lenses for underwater use. Ikelite’s custom optical grade acrylic domes components provide the colour, clarity, and durability of glass at a fraction of the travel weight and cost.
Durability and corrosion-free performance
Ikelite’s white ABS-PC blend housing provides strength and corrosion-free performance year after year with minimal maintenance. ABS-PC is lighter than aluminium for convenience during travel and less drag underwater. The specially formulated colour deflects the sun to keep your camera running cooler, and longer. Compared to black or clear housings, the light colour provides superior contrast for an enhanced view of the camera, LCD screen, and o-ring seal.
