AOI Announces Housing for Olympus E-M1 Mark III
By Ian Bongso-Seldrup, April 11, 2022 @ 08:00 PM (EST)

AOI has released details of its new housing for the Olympus OM-D E-M1 Mark III. The third iteration of the midrange Micro Four Thirds camera boasts a 20MP sensor, 18fps burst shooting (with AF), and DCI 4K/24p video recording.

The polycarbonate housing features a “new and improved” integrated optical trigger, which allows underwater shooters to make full use of the camera’s Super FP mode. With this high-speed flash sync option, it is possible to use a faster shutter speed than the maximum sync speed of 1/200s—useful when capturing fast action or when using wide apertures. AOI’s Vacuum Analyser & Wet Detection System comes pre-installed, giving users audio and visual alarms should the housing seal become compromised.

Shipping in May 2022, the housing is available for USD999 from retailers such as Backscatter. (Note that with minor modifications, the housing is also compatible with the E-M1 Mark II; consult your dealer for more information.)

AOI’s latest housing – ready to catch all the action

Essentially, underwater housings allow the user to take their camera scuba diving. Protecting it from water and the pressure when underwater, basically the same premise from 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. 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 which allows shutter speeds to be used faster than the x-sync capability of the camera-flash system.

When do we use Super FP flash mode?

When you need wide aperture for shallow depth of field, such as when shooting macro and a bokeh effect is desired.


When we 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 the 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 analyse 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.

The housing is available for pre-order and delivery is expected to commence in May 2022. The housing is expected to sell for USD999.00 (price will vary depending on local taxes and business terms).
