Pentax WG-90 point and shoot camera announced

New rugged and waterproof adventure camera in the WG series

By PF Staff in Pentax Announcements on Nov 19, 2023

On November 15, 2023, RICOH announced a new incarnation of the WG series of rugged point and shoot cameras, the Pentax WG-90.

Pentax WG-90

The technical specifications are identical to its predecessor, the Ricoh WG-80. The only difference appears to be the branding. The WG-90 is branded Pentax as were the initial cameras in the WG series up until and including the WG-3 and WG-10.

The WG-90 is available in blue and in black. It is water proof down to 14 meters (45 feet), and drop, dust and crush proof within limits. Besides the built-in flash it features a built-in macro ring light for macro shooting like its predecessors.

The camera has a 16 mega pixel back-illuminated CMOS sensor paired with a 5-25mm zoom lens (approximately 28-140mm in 35mm format equivalent). The lens is also capable of extreme close focusing, with a macro mode getting as close as 1cm, and 10cm across the entire zoom range.The camera interface is designed to be both easy to use as well as very versatile, with 25 shooting modes and many creative digital filters. There are specific underwater still and movie modes designed to get pleasing color and contrast in underwater captures. There are also various features to assist with portraits and selfies; such as smile capture, which automatically releases the shutter when the subject smiles, blink detection, which helps prevent shots with the subject's eyes closed, and a self portrait assist mode that illuminates one or more of the six front LEDs to indicate where in the frame a face or faces are located.

As of the time of writing the launch price is unknown.

The official press release from Ricoh:

Standard-class, waterproof digital compact camera, designed for casual underwater photography to a depth of 14 meters


TOKYO, November 15, 2023 RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the PENTAX WG-90 digital camera, featuring outstanding waterproof and shock-resistant performance and a host of user-friendly shooting functions in a compact, lightweight body.

Despite its compact, lightweight body, this standard-class, waterproof digital compact camera is designed to be waterproof down to a depth of 14 meters, shockproof against a fall from a height of 1.6 meters, and freeze-proof against temperatures as low as -10°C. It assures outstanding reliability and operability even under harsh conditions where ordinary compact cameras and smartphones often become unusable. It comes equipped with an outdoor-friendly monitor, which swiftly optimizes the image brightness level to improve the visibility of a scene in bright outdoor locations.

It also features the PENTAX-original Digital Microscope mode, which allows the user to capture clear, vivid images of a microscopic world normally undetectable with the naked eye. This model can be used for a wide range of scenes and subjects, ranging from casual snapshots to outdoor and underwater photography, and even in specialized worksite applications.

The RICOH WG-80 is equipped with a back-illuminated CMOS image sensor with approximately 16 effective megapixels and a high-performance imaging engine, delivering super-high-resolution still images and HD video clips. It features triple anti-shake protection to prevent blurred images and videos in all applications.

Over the years, PENTAX has developed and marketed dustproof, waterproof or weather-resistant products, all of which have been well received and highly respected by many users. This product lineup will be further expanded in the future, while marketed under the PENTAX brand beginning with the PENTAX WG-90 -- just like the PENTAX digital SLR lineup, in which all models are designed to be dustproof and weather-resistant.

Main Features of the new PENTAX WG-90

  1. Heavy-duty construction assuring underwater shooting down to 14 meters (46 feet), for up to two hours of continuous operation

The WG-90's solid, airtight body is not only waterproof down to a depth of 14 meters for up to two hours of continuous operation (equivalent to IPX 8 or JIS Class 8), but is also shockproof against a fall from a height of 1.6 meters,* and dustproof (equivalent to IPX 6 or JIS Class 6), freeze-proof to temperatures as low as -10°C, and crushproof against weights up to 100kgf (kilogram force).** Thanks to this heavy-duty construction, the WG-90 performs superbly and dependably even in harsh, demanding outdoor conditions.

* Measured under RICOH IMAGING-original testing standards — from a height of 1.6 meters, onto a surface of 5cm-thick plywood — conforming to Method 516.5-Shock of the MIL-Standard 810F.

** Measured under RICOH IMAGING-original testing standards.

  1. Exceptional image quality

The WG-90 is equipped with a back-illuminated CMOS image sensor, which assures excellent high-sensitivity and low-noise characteristics and high-speed readout of image data signals. Coupled with a high-performance imaging engine, this image sensor delivers a top sensitivity of ISO 6400 and super-high-resolution images with approximately 16.0 effective megapixels. It also provides advanced image processing functions, made possible by super-resolution technology, to deliver sharper, clearer, higher-resolution images. It even offers such innovative shooting features as Handheld Night Snap mode, which automatically produces a single, blur-free composite image using several images of the same nighttime scene.

  1. Six Macro Lights to assist close-up photography

Ideally positioned around the circumference of the lens barrel for macro shooting, six LED Macro Lights provide bright, uniform illumination on a subject when the Digital Microscope mode is selected to magnify a given subject on the LCD monitor, closely observe the microscopic world undetectable with the naked eye, and capture the subject in a high-resolution macro image. In the Macro Lighting mode,***the camera even allows the user to adjust the illumination intensity in five levels, and optimize the close-range flash photography based on the subject or the photographer's creative intention.
In order to minimize camera shake and subject shake, the Instant Illumination Enhance function lets the photographer use a higher shutter speed by automatically raising the discharge level of the Macro Lights at the moment of shutter release. The Self-Portrait Assist mode uses the blink of an LED lamp to check if the subject's face has been safely captured within the picture frame, while the LED Lighting mode makes the Macro Lights function as a lighting device in the dark.

*** The Macro Lights can be used in Program, Movie and Report modes.

  1. 2.7-inch LCD monitor with Outdoor View Setting mode

The WG-90 comes equipped with a 2.7-inch LCD monitor with horizontally expanded 16:9 proportions and approximately 230,000 dots. Thanks to the AR (Anti-Reflection) coating applied to its surface, the monitor minimizes annoying glare and reflections to assure a sharp, clear on-screen image, even in the harsh sunshine often encountered during outdoor shooting. It also provides the Outdoor View Setting mode, which automatically optimizes the monitor's brightness level for a given lighting condition to improve the visibility of the on-screen image.

  1. Underwater-exclusive shooting modes

Based on the data of images actually captured underwater, the WG-90 provides the Underwater and Underwater Movie shooting modes, both of which are programmed to effectively compensate for the loss of contrast caused by the diffusion of light in the water, while enhancing the reddish hues which fade away in the water. These underwater-exclusive modes allow the user to capture sharp, clear images of underwater scenes.
In the Underwater mode, the Flash Off + Flash On option allows the user to consecutively capture two images with a single shutter release -- one without flash and another with flash.

  1. 5X optical zoom lens with a 28mm wide-angle coverage

The WG-90 features a high-performance, five-times optical zoom lens with a focal-length coverage from 5mm to 25mm (equivalent to approx. 28mm to 140mm in the 35mm format) to accommodate a wide range of scenes and subjects, including sweeping landscapes. It also provides other user-friendly shooting functions such as: the Intelligent Zoom function that extends the zoom range by approximately 36 times**** (equivalent to 1008mm in the 35mm format) for super-high-magnification telephotography without compromising image quality; and an interval shooting mode that comes in handy for fixed point photography.

**** This function is available when the recorded size of 640 is selected.

  1. Triple anti-shake protection to prevent blurred images in all applications

(1) Pixel Track SR mechanism
When recording still images, this advanced shake-reduction mechanism effectively compensates for camera shake by digitally processing affected images.

(2) Digital SR mode
When the camera detects low-light conditions in still-image shooting, this mode automatically raises the sensitivity to as high as ISO 6400, making it possible to use a higher shutter speed and effectively minimize the adverse effect of camera shake and subject shake in poor lighting conditions.

(3) Movie SR mode
During movie recording, this mode effectively compensates for the misalignment of images caused by camera shake through the use of exclusive software to produce beautiful, blur-free movie clips.

  1. Full HD Movie recording for extended shooting of high-quality movies

The WG-90 provides Full HD movie recording using the H.264 recording format, letting the user capture high-quality, extended movie clips (1920 X 1080 pixels, 16:9 proportions) at a frame rate of 30 frames per second. To add some creative touches to movie recording, it also features a high-speed camera function* for slow-motion playback of captured movie clips, and an interval movie function. A micro-HDMI terminal (type D) is also provided on the camera body for simultaneous output of Full HD movie clips and sound to external audio-visual devices.

* When this function is selected, the recorded size is fixed at 1280 X 720 pixels.
