Underwater housing Ikelite for OM System OM-1 housing

Ikelite's OM-1 housing are designed from the ground up to provide full camera control and connection for external strobe lighting out of the box.

The housing

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.
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.

Vacuum system
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.

Viewfinders
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 #IK6890.2 or 45° Magnified Viewfinder (Type 3) #IK6891.3.

Strobes
You can enjoy the fastest and most accurate TTL exposure on the market by adding the 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.
This camera does not feature a built-in flash for the triggering of fiber optic strobes.
