Fantasea FRX100IV Housing Review
The Fantasea FRX100IV housing delivers full access to the controls of the Sony RX100 IV, allowing you to shoot incredible images, 4K video and much more. The Sony RX100 IV packs a whopping 1" sensor into the body of a compact camera, and sits at the top of Bluewater Photo's Best Compact Cameras list.
If you haven't yet, be sure to read our Sony RX100 IV Camera Review.
The polycarbonate plastic Fantasea FRX100 IV is the lightest housing available for the RX100 IV. The clearly labeled controls, affordable price and wide range of accessories make it a great choice for underwater photo and video shooters. In this review we will take a deeper look at the housing.

Housing Ergonomics and Controls
The Fantasea RX100 IV housing is easy to hold in your hand, with nooks for your fingers and thumb to settle into. The shutter release is a button pressed vertically, which is nice for a handheld housing. The control placement mirrors the button layout on the camera body, which is nice for those who transition back and forth from using the camera on land and underwater - no hunting around for a button that has been moved to a mysterious position.
The plastic button heads are wide, making them easy to push with bare fingers or thick gloves, and each is very clearly labeled. The housing provides a knob for adjusting the front control ring, however since it is on the left side of the housing, it requires a second hand to adjust.
The video record button is easy to reach and press, but this makes accidental video recording very easy.
A standout feature is the knob for spinning the rear control dial, which is a feature unique to Fantasea.
Opening and Closing
To open and close the housing, you depress a small plastic lock tab, then twist the side latch. While this may not feel robust at first, a closer inspection reveals a very secure locking mechanism. The camera can be set into place within the housing, making it easy to replace batteries and memory cards - and no need to unscrew the camera from a tray each time. The clever spring action of the back LCD skirt holds the camera in place in line with housing controls.
There is also enough space in the housing to remove the camera with fingers (instead of shaking the housing upside down, as is the method with many compacts). A double o-ring seal provides extra safety and is still easy to inspect and service.
One huge bonus is the built-in leak detection system. The sensor is place at the absolute bottom of the housing, meaning it will be triggered at the first presence of water in the housing.
The housing comes with a hand strap and flash diffuser in the box, so you're ready to go whether you are shooting with or without external strobes.
A lens port adapter is also included, opening up the world of m67 mount wet lenses for macro and wide-angle photography. Check out our recommended accessories for the Fantasea FRX100IV.
