AOI Olympus OM-D E-M1 II & III Underwater Housing UH-EM1III

AOI Olympus OM-D E-M1 II & III Underwater Housing UH-EM1III

Essentially, underwater housings allow the user to take their camera scuba diving. Protecting it from water and the pressure when underwater, is basically the same premise as 160 years ago when the first underwater photographs appeared. The new UH-EM1III underwater housing for the Olympus OM-D E-M1MKIII takes it to the next level. Integrated with a new and improved optical trigger, it is compatible with the RC Flash mode of the E-M1 MKIII. Allowing users to capitalize on one of the key features of the camera when underwater - Super FP mode.

Due to the limitations of sync speed and underwater strobes in general, most photographers are stuck with shutter speeds of 1/200 or 1/250. But with the new and improved optical trigger, photographers are now able to use Super FP Mode, TTL, or Manual.
 
What is Super FP
Super FP is a special flash mode that allows shutter speeds to be used faster than the x-sync capability of the camera-flash system.
 
When do you use Super FP flash mode?
When you need a wide aperture for shallow depth of field, such as when shooting macro and a bokeh effect is desired.

Or

When you are shooting fast-moving animals, the fast shutter speed will prevent motion blur due to the subject moving.

By being able to utilize these modes, photographers no longer have to work around these limitations.

The design of the new housing reflects the wants and needs of mirrorless users. By keeping the housing compact and ergonomic, it makes it easy to handle and travel. Although small, the buttons and knobs are sensibly laid out and intuitive to the user.

To ensure that everything works as it should, the housing is pre-installed with a Vacuum Analyser & Wet Detection System. Using the vacuum pump to arrive at the desired internal pressure, the system will continuously analyze the internal pressure. Once a change is detected, the audio and visual alarms are set off to provide users ample time to rectify the situation.
