The 4x optical zoom lens achieves a 35-140mm focal length (35mm equivalent) while allowing the camera to maintain a compact size. The lens construction incorporates 8 elements in 7 groupings, including two aspherical elements to maximize sharpness across the whole image. With a maximum aperture range of f2.8 (wide) to f4.1 (telephoto), the lens is remarkably bright at the telephoto end.
ISO 800 mode improves results when shooting in low-light settings and enables flash-free photography indoors. The camera's High ISO Auto setting prioritizes fast shutter speeds by automatically using the higher range of ISO sensitivities, reducing the risk of unwanted image blur.
Improved LCD and playback
A larger 2.5-inch vari-angle LCD screen enables accurate framing from unusual angles, such as those encountered when using the 1-centimeter (.4-inch) Macro mode. The enhanced user interface (UI) retains a selectable Grid Line display to assist with rule-of-thirds compositions, while users can also enable a new 3:2 ratio overlay during shooting to view the printable area for standard photo prints. Playback is enhanced with an overexposure warning feature, which indicates overexposed areas in captured images.
Flexible shooting
The PowerShot A630 offers users a range of versatile features for creative photography. A choice of 21 shooting modes includes Program, Aperture priority, Shutter priority, and full Manual modes for complete exposure control. A Second Curtain Sync function allows for creative flash exposures, such as light trails. Artistic photo effects can be applied in-camera during and after shooting with My Colors.
Filming is also possible at a high standard--VGA quality movies can be captured with sound at a smooth 30 frames per second (fps). The AV-out connection and supplied cable allows for full screen playback on a TV.
Full range of accessories
A comprehensive range of optional lenses and accessories includes wide (0.7x) and telephoto (1.75x) converter lenses. The optional High Power Flash offers further flexibility for night time photography, while an optional waterproof case allows full control at depths of up to 40 meters. (Accessories are not included and must be purchased separately.)
