Another camera I am bringing into the fold of my CCD collection is the Pentax Optio W90, a go-anywhere rugged compact fitted with a 12MP CCD sensor, designed to be dustproof, waterproof down to 6 meters, coldproof down to -10°C (14°F), and shock-resistant for drops of up to 1.2 meters. The camera, introduced in 2010, has a 5x (28-140mm equivalent) zoom lens, a 2.7-inch LCD, a Digital Microscope mode, HD video recording, and a face detection system that also recognizes up to three pet faces.
Performance specs for the digital compact include a normal shutter speed range from 1/4 to 1/1,500 seconds, up to 4 seconds in Night Scene mode, and a self-timer with two- or ten-second delay. Normal ISO sensitivity is from 80 to 1,600, controlled either automatically or manually, and six white balance modes, namely Auto, Daylight, Shade, Tungsten, Fluorescent, and Manual. ISO sensitivity can be expanded to ISO 3,200 or ISO 6,400 under manual control, or in the automatic Digital SR mode, by dropping image resolution to five megapixels.
Exposure modes on the Pentax W90 include a Green (fully automatic) button, Auto Picture, Program, and a huge selection of scene modes that include Night Scene, Movie, Underwater, Underwater Movie, Landscape, Flower, Portrait, Digital Microscope, Digital Wide, Digital Shake Reduction, Surf & Snow, Kids, Pet, Sport, Fireworks, Candlelight, Night Scene Portrait, Text, Food, Digital Panorama, Frame Composite, and Report.
The Pentax W90 uses a 9-point contrast detection autofocus system, which includes face detection capability. Shots are framed and reviewed on a 2.7-inch LCD with 230,000 dots of resolution with anti-reflective coating and a wide viewing angle, features that make it easier to view the LCD in difficult conditions. The W90 does not come with any form of mechanical stabilization, but is installed with the 'Pixel Track' Shake Reduction algorithms for correcting blur caused by camera shake.
Power to drive the camera operation is derived from a D-LI88 lithium-ion rechargeable battery; images and movies are stored on SD or SDHC flash cards, or in the camera's 26.7MB built-in memory. Connectivity options include a USB 2.0 High-Speed, as well as a high-definition HDMI and standard definition composite NTSC / PAL video output. The camera measures 107.5 x 59 x 25mm and weighs 161 grams with the battery and SD card installed. Battery life is rather short, though, with a CIPA rating of only 205 shots.
The multitude of functionalities of the W90 is spread over a couple of display selections assessed via the Mode button (for Scenes) on the Four-way controller pad, and Edit functions accessed from Playback mode (press Playback and Mode to access). Edit function includes Slideshow, Image Rotation, Small Face Filter, Ink Rubbing Filter, Collage, Digital Filter, Original Frame, Frame Composite, Movie Edit, Red-eye Compensation, Subscreen Input, Resize, Cropping, Image/Sound Copy, Voice Memo, Protect, DPOF (Print Setting), Image Recovery, and Start-up Screen.
Camera setting, a four-page menu selection, is assessed via the Menu button. Setting options range from Image Tone, Recorded Pixels, Quality Level, ... all the way down to Data Imprint, and Macro Light. Beside the Menu button on the back of the camera is the Face Detection cycle button with options for Face Detection On, Off, and Smile Capture. Other buttons on the back of the camera include the (+) and (-) Zoom selector, the Self-timer, Flash mode, and Macro mode selection on the Four-way controller pad, and the multi-function Green button.
