This Ikelite housing for the Olympus E-410 camera is an injected molded clear polycarbonate case known for its strength and corrosion-free properties. The housing offers an unobstructed view of the camera's information and control functions and operates safely to a depth of 200'. Camera installation is quick and simple and the o-ring seal can be checked visually through the clear housing. The release handle system allows for easy attachment and removal of SubStrobe mounting arms at the touch of a button. The housing is sized and weighted for near neutral buoyancy and superb handling underwater. This housing has circuitry that converts Olympus TTL signals from the hot shoe for TTL compatibility with the DS-51 and DS-125 SubStrobes. This is not a TTL by "watching the camera strobe" slave system but real Olympus TTL control when connecting strobes by a sync cord. The TTL mode provides four 1/3 f/stop increments over or under flash compensation that is added to or subtracted from any compensation entered into the camera. Seven manual power settings in half-stop increments allow for complete creative control. All choices are obtained by simply rotating a knob on the housing back. An assortment of interchangeable lens ports allows use of most macro wide angle and zoom lenses. The Ikelite Super-Eye magnifier comes standard and offers enhanced visibility of the camera's viewfinder while wearing a diving mask. The camera's live-preview feature can also be used to its full potential with an unobstructed view through the back of the housing. Note: Requires Lens Port to match specific lens on SLR camera. Please also note that zoom lenses require addition of a Close-Up #4 diopter filter on the lens. Click here for port chart
