Developed as the top-of-the-line models of the dependable, heavy-duty PENTAX WG series, the WG-3 GPS offers the series’ best waterproof performance (down to 14 meters underwater) and shock resistance (against a fall from a height of two meters). It also features a newly designed, large-aperture, four-times optical zoom lens (with the maximum aperture of F2.0 at wide-angle end), a high-sensitivity, back-illuminated CMOS image sensor, and a new-generation imaging engine to deliver high-quality, low-noise images — even in the water, at night and indoors where the subject is poorly illuminated. Adding such outstanding features as –10°C cold resistance, dual shake reduction system, Full HD movie recording (1920 x 1080n pixels) and a high-performance, wide-frame 3.0-inch LCD monitor, the WG-3 GPS performs dependably and brilliantly in a wide variety of demanding outdoor scenes.
<b>Heavy-duty construction for underwater shooting</b>
By further enhancing the watertight capability of the camera body, PENTAX has upgraded the WG-3 underwater performance to 14 meters, compared to 12 meters for its predecessor, and for up to two hours of continuous operation (equivalent to IPX8 or JIS Class 8 waterproof performance). This camera is also designed to be highly shock-resistant, dustproof, cold-resistant, and crushproof. All these features make the WG-3 dependable, heavy-duty imaging partners in harsh, demanding outdoor conditions.
<b>4x optical zoom lens with maximum aperture of F2.0</b>
The newly designed optical zoom lens offers a maximum aperture of F2.0 to capture bright, clear images with minimal noise, even under dimly lit underwater conditions. With its four-times zoom coverage from 4.5mm to 18mm (equivalent to approx. 25mm wide angle to approx. 100mm medium telephoto in the 35mm format), this versatile zoom lens accommodates a wide range of applications - from macro shooting of flowers to wide-angle shooting of spectacular landscapes. The camera’s Intelligent Zoom function also extends the zoom range to approximately 28.8 times to cover the focal length of an approximately 720mm super-telephoto lens (in the 35mm format) to capture extra-high-magnification images without compromising image quality.
<b>High-performance, back-illuminated CMOS image sensor</b>
The WG-3 comes equipped with a state-of-the-art, back-illuminated CMOS image sensor, which is superior in high-sensitivity and low-noise characteristics to conventional sensors and assures high-speed readout of image data signals. Coupled with a new-generation imaging engine, this image sensor delivers a top sensitivity of ISO 6400 and super-high-resolution images with 16.0 effective megapixels. These models also provide advanced image processing functions made possible by the latest super-resolution technology to assure sharp and clear images. It even offers such innovative features as a Handheld Night Snap mode, which automatically captures four images of the same scene and produces a single blur-free, composite image from them.
<b>Dual anti-shake protection for sharp, blur-free images</b>
The WG-3’s dual shake reduction system combines an image-sensor-shift-type SR (Shake Reduction) mechanism with a Digital SR mode to more effectively compensate for the adverse effects of camera shake and subject shake in shake-prone conditions, such as when capturing poorly lit subject with ambient light only, or when shooting sunset scenes.
<b>Six LED Macro Lights to assist close-up shooting</b>
By positioning six LED Macro Lights around the circumference of the lens barrel for macro shooting, the WG-3 provides brighter, more uniform illumination on the subject when the Digital Microscope mode is selected. With the Macro Lights, the user can clearly see a magnified view of a microscopic world often unnoticeable with the naked eye on the camera’s LCD monitor and effortlessly capture eye-catching images. In order to minimize camera shake and subject shake, the instant illumination enhance function allows for the use of a higher shutter speed by automatically raising the illumination level of the Macro Lights at the moment of shutter release. In addition, the Macro Lights can provide other user-friendly features, such as a Self-Portrait Assist mode to check if the subject’s face is safely captured within the picture frame using the blink of an LED lamp, and a LED lighting mode to use the Macro Lights as a lighting device in the dark.
<b>Advanced GPS functions</b>
The WG-3 GPS comes equipped with a sophisticated GPS module, which automatically records position data* and travel log data onto captured images and adjusts the built-in clock to local time. Thanks to newly incorporated pressure sensor and digital compass, the user can not only check the pressure, altitude/underwater depth and direction of a shooting location, but also record such data onto captured images for future reference.
<b>Other features</b>
- Two remote control receptors (one in front and another on the back) to widen signal coverage
- Digital level to check the camera’s horizontal/vertical inclination
- Auto Picture mode to automatically select the most appropriate shooting mode from 16 different scene modes
- Digital Wide mode to compose an extra-wide-angle picture (equivalent to approx. 19mm wide angle in the 35mm format) from two separate images
- Carabiner strap (included) for hooking the camera to a backpack or other outdoor gear
- 12 digital filters
- Image viewing, editing and filing software included: MediaImpression 3.6.2 LE (Windows version compatible with Windows 8) and MediaImpression 2.2 LE (Macintosh version compatible with Mac OS X 10.8)
- Compatibility with Eye-Fi wireless LAN SD memory cards
