WG History
History of Toughness Beginning
with Waterproofing

Waterproof function is the core element of WG.
Its history began in the film camera and the progress still continues.

WG History

Challenge to waterproofing that started in the film camera

ZOOM 90WR
Released in November 1991

The world’s first water resistant compact zoom camera

ZOOM 90WR is the world’s first water resistant compact camera with a zoom lens out of the compact cameras produced in the film camera.
In addition to JIS Standard compliant waterproofing function that enables whole washing with tap water, ZOOM 90WR required a high level technology, unique to a zoom lens and unnecessary for a single focus lens, to “let air through while preventing water from passing through.” Pursuit of this camera built the real beginning of the history of waterproofing leading to WG, a tough camera.

at the water depth of one meter for 30 minutes.

Optio 33WR / Optio 43WR are epoch-making models that were produced in the changing days from the film camera to the digital camera and required new waterproof technology.
The bending optical system was adopted to the lens and functions, such as increase in the number of shots by using a memory card, were added. In spite of increase of electric parts used for the camera due to adoption of the digital system, these models were capable of being left at the water depth of one meter for 30 minutes and realized a shocking experience of “putting a camera, an electronic device, into natural enemy water.”

Waterproof camera that enabled underwater photography
for the first time in the world.
