Sony CyberShot DSC-TX5 Review

Posted on Wednesday, Jun 1 2011 on 04:00 PM

The Sony Cyber-shot DSC-TX5 digital camera is a slim, stylish pocket digital camera that has a secret: It's waterproof. The Sony TX5 is based around the combination of a 10.2-megapixel CMOS image sensor and a 4x optical zoom lens. The Sony TX5's sensor is what's known as a backside illuminated (BSI) design, meaning that its circuitry is placed on the non-light-gathering side of the sensor, allowing the maximum area of the sensor's other side to be devoted to light gathering. This should translate to higher sensitivity, and to reduced noise levels when compared to a non-BSI sensor for the same sensitivity. Actual focal lengths vary from 4.43mm to 17.7mm, equivalent to a range of 25 to 100mm in still image mode. This equates to everything from a generous wide-angle to a moderate telephoto. When shooting high-def movies, the sensor crop raises the effective focal lengths to a range of 28 to 112mm, and for standard-def movies the range is equivalent to 34 to 136mm.

The Sony TX5 has a maximum aperture which varies from f/3.5 to f/4.6 across the zoom range. At wide-angle the minimum aperture is f/6.3. To help combat blur from camera shake, the Sony DSC-TX5's lens includes an optical stabilization mechanism which works in concert with a built-in gyro sensor to detect and correct for camera motion. As is sadly the norm for most compact cameras these days, the Sony Cyber-shot TX5 doesn't include any form of optical or electronic viewfinder. Instead, Sony has opted for a 3.0" Clear Photo Plus LCD display with a resolution of 230,000 dots, roughly equating to a resolution of 320 x 240 dots with three dots per color. Overlaid on the LCD display is a touch panel, allowing it to double as an input device with intuitive operations like flicking or drag and drop used to control camera functions.
