To secure waterproof property, buttons and dial levers are not directly attached on a housing body but installed via brass bearings to prevent the aluminum housing body from galling caused by sliding of buttons and movement of dial levers. If bearings become worn, they can be replaced with minimum necessary parts.
Buttons and dial levers carry oil bearing type INON yellow O-rings as same as housing body O-ring to prevent accidental flooding due to lack of grease. Also their size is thicker than required to enhance waterproof property.
Bearings for dials have double O-ring structure for stable movement and further waterproof performance.

The X-2 for GF2 has ideal body size not too compact to naturally hold and access to controls with wearing gloves for unimpeded underwater shooting. The body design allows you to put right hand fingers on the integrated grip naturally to hold the housing securely without effort.
The position and angle of the shutter release lever has been carefully examined based on user’s position and hand location at the moment of taking a picture where the user checks the LCD monitor on the back of the housing, to support natural and smooth operation of the shutter release lever to suppress camera shake.

Buttons and dials are carefully arranged for quick access to them underwater without changing right hand position. Large "LCD monitor window" provides visual contact with camera's control buttons to enhance intuitive operation as like on land even underwater.

*The "iA button" and "touch panel" are not accessible since they are rarely used underwater. The "Rear dial" can be rotated from housing control but cannot be pressed. However almost all settings by the "Rear dial" can be also managed by the "Q.MENU" button and "Cursor" buttons.

A camera is precisely fixed in the housing at the tripod-screw and both shoulder strap eyelets. Since neither of front nor side of the camera contacts with the housing, water-pressure never cause any unexpected operation of the camera.
You can put the camera in the housing even with an optional leather panel kit or thick LCD monitor protector being attached.
Spacious inner construction allows you to put fingers between the camera and the housing to pull out the camera easily by one hand, and further helps to gain buoyancy to have less underwater weight.
The built-in flash can be completely closed by a housing control lever to prevent accidental damage on the built-in flash unit when removing the camera.

Flooding-free four Optical D Connectors are equipped as standard feature to benefit simple yet reliable "S-TTL" Auto with maximum four external strobes supporting accurate exposure simply by pressing the shutter release button even in high power multi-lighting circumstances allowing you to focus on artistic intention or composition. Effective and reliable transmission of the built-in flash light is the key factor to enhance optimum accuracy of the S-TTL Auto exposure system. The X-2 for GF2 housing is equipped with a guide rail to hold the built-in flash at ideal pop-up position to ensure you with stable S-TTL Auto exposure.
