Steves-Digicams reviews Canon PowerShot A590 IS 8.0MP digital camera
The lightweight and compact 8-megapixel PowerShot A590 IS camera is one of several A series models for 2008. Featuring a versatile 4x (35mm-140mm equivalent) zoom lens, 2.5-inch LCD, Face Detection AF, and various exposure modes, the A590 IS offers a rich feature set for an entry-level PowerShot cameras.
Staking out the upper-middle tier of the PowerShot A-series, the new camera offers users the option of 19 shooting modes, from fully automatic to fully manual operation for greater creative control. The A590 IS camera also features Canon's advanced Optical Image Stabilization (OIS). OIS significantly reduces the effects of camera shake (and the blurry pictures they cause) by actually allowing the lens to shift to compensate for camera movement or shake. Unlike electronic image stabilization systems that essentially mask the movement rather than actually compensating for it, Canon's Optical "lens shift" system preserves the inherent quality of the stabilized image without covering up parts of the image. This OIS technology is even effective when the movement being stabilized is caused by extended telephoto or low-light shooting conditions.
Canon's innovative and exclusive Motion Detection technology consolidates motion information for both the camera and the photographic subject and determines whether the subject has moved and what if any adjustments to focus or exposure needs to be made. It will even detect and assess subject movement between each frame, making it quicker and easier to capture a series of images. Additionally, when paired with Canon's Optical Image Stabilization system – the motion detection system's onboard vibration-detecting gyro senses and compensates for movement due to camera shake, even if the subject remains still...
