Pentax Optio WG-2 GPS: Lab Test Results & Comments
The camera offers automatic exposure settings only plus many scene modes. To change parameters the photographer has to use a four-way cursor field and some other function elements. All of these elements are sealed to protect them from dust and water. The function elements are very small, which makes them somewhat unwieldy, especially when wearing gloves (for skiing and diving, for example). The camera has two sealed protective covers on the bottom side (which protects the rechargeable battery and the SD card slot) and a cover for the USB/TV combo port and the HDMI interface. The flash and the lens system are totally integrated into the camera and stay within the body, even in activated state. This also helps protect the camera.
The camera offers a standard mini flash system for portrait fill at a distance of up to about 15 feet. In addition, it has six LEDs that encircle the front lens. These LEDs are activated when taking macro shots and allow the user to shoot very tiny objects without shadows.
The Pentax Optio WG-2 GPS offers a large LCD screen on the back, which is used as an electronic viewfinder and control center for all camera settings. It offers 460,000 RGB dots and shows a brilliant, very crisp image.
The WG-2 doesn’t allow the user to set aperture or shutter priority mode or make manual mode settings. In their place it offers numerous scene modes, which cover a lot of sport scenes like underwater photo and underwater video. A special “digital wide angle” mode works like the panorama mode of other digital cameras by combining two shots into a
A GPS system is able to record geographical data. This information is integrated into the EXIF data of each image and allows the user to retrace photos of a holiday trip on Google Earth and to use the data in image management software. It is very easy to use the GPS module: the photographer has to activate this function in the setup menu and the camera will then automatically record the GPS signal.
Color: The automatic white balance system of the Pentax Optio WG-2 GPS showed a shift into cooler colors and a boost for intense blue colors. Skin tones are reproduced very exactly, and most other nuances show only minor color errors. Red nuances are nearly perfect. This is very unusual for compact cameras, which generally boost red colors with higher magenta and yellow rates.
Sharpness: The camera showed a good performance in our resolution test. It reproduced the ISO 12,233 chart with 2883 of its nominal 3456 lines in picture height. However, it uses a fairly intense sharpness filtering to compensate for the anti-noise filtering. This results in a slightly artificial look in the hair structure of the model shot and some small halos on extreme contrast lines, like the Siemens star in our standard test box shot. The differentiation of red nuances is very good. The structure of the fabric (T-shirt) in our model shot is clearly differentiated.
Noise: Noise results stay on an acceptable level in all images taken with speed settings up to ISO 400. Color noise is visible in images taken with ISO 400 and higher. The camera uses an intense anti-noise filtering system, which smooths image details in images taken at ISO 800 and higher in a noticeable way. Especially in the highest ISO settings of 3200 and 6400, an “impressionistic” look caused by the anti-noise system is clearly visible.
The camera showed an average performance in our dynamic range tests: it achieves a maximum of 9.38 f/stops, but the dynamic range declines to 8.6 or 8.3 f/stops in higher ISO speed settings (more than ISO 400).
