WG-4 - 16.79MP, 1/2.3" CMOS, 4608 x 3456, Full HD, ISO 125 - 6400, TTL, 7.62 cm (3 ") TFT LCD, 70 MB, USB 2.0, HDMI
<b>Heavy-duty construction for underwater shooting to 14 metres deep, and up to two continuous hours</b>
Thanks to its fully watertight construction, the WG-4 assures outstanding waterproof performance to a depth of 14 metres, and for up to two hours of continuous operation (equivalent to IPX8 or JIS Class 8). It is also designed to be shock-resistant against a fall from a height of two metres, dustproof (equivalent to IPX6 or JIS Class 6), cold-resistant against temperatures as low as –10°C, and crushproof against weights up to 100kgf (kilogram force).
All these features make it truly dependable, heavy-duty digital imaging partner in harsh, demanding outdoor conditions.
<b>Exceptional image description, thanks to a large-aperture zoom lens and latest imaging technologies</b>
The high-performance optical zoom lens offers a maximum aperture of F2.0 (at wide-angle end) to capture bright, clear images with minimal noise, even in dimly lit locations. 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 photography of sweeping landscapes.
Thanks to the upgraded AF algorithm, the focusing speed in macro shooting has been greatly increased to facilitate close-up applications.
In the Underwater and Underwater Movie modes, the color rendition and contrast of a captured image are automatically optimized based on the original image data: Red tints and shades, which tend to be lost in underwater photography, are enhanced for true-to-life colour rendition, while the loss of contrast caused by the diffusion of light in the water is effectively compensated for sharper, clearer images.
<b>A comprehensive selection of shooting modes</b>
Including the Shutter Priority and USER modes, which are installed for the first time in the WG series, the WG-4 provides a total of 29 shooting modes. In the Shutter Priority mode, the camera automatically sets the aperture and ISO sensitivity for a user-selected shutter speed to assure optimum exposure. In the USER mode, the photographer can instantly recall preprogrammed settings for more personalized camera operation. In addition, the Auto Picture mode automatically selects one of 16 different scene modes for a given scene or subject. With a wide choice of shooting modes, the user can always find the ideal mode for every subject and occasion.
<b>High-performance, back-illuminated CMOS image sensor</b>
The WG-4 comes equipped with a state-of-the-art, back-illuminated CMOS image sensor, which excels in high-sensitivity and low-noise characteristics, and assures 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 16.0 effective megapixels. That model also provides advanced image processing functions made possible by the latest super-resolution technology to assure sharp, clear, high-resolution images. It even offers such innovative features as a Handheld Night Snap mode, which automatically captures multiple images of the same nighttime scene and produces a single blur-free, composite image from them.
