Product Description
|
|
A compact, lightweight standard zoom lens with superior optical performance plus a built-in Image Stabilizer. The IS system reduces the possibility of blurred photographs caused by camera shake, enabling hand-held photography in comparatively dim light without a flash or tripod. The IS system is composed of a pair of gyro sensors to detect vertical and horizontal motion and a microprocessor that compensates for it by shifting special IS lens elements in parallel with the perceived movement. At the wide-angle end of the zoom range, the equivalent shutter speed gain is approximately 1.5 stops while at the telephoto end, it is approximately 2 stops. In addition, the lens has a USM drive mechanism for optimum AF performance, and the pulse control diaphragm (EMD) ensures precise aperture control.

Major Features:
|
- Broad zoom range includes popular focal lengths, from 28mm wide-angle
for tight interiors and group shots, to 135mm telephoto, great for sports,
nature photography or portraits.
- Image Stabilizer mechanism compensates for camera shake, permitting
hand-held photography at the slower speeds necessary in dim light when the use of
flash or a tripod is undesirable, impractical or forbidden. Choosing slower speeds
also allows use of smaller apertures, resulting in increased depth-of-field.
- Advanced ring-type Ultrasonic Motor (USM) drive delivers precise,
silent, high-speed autofocusing. (Full-time manual focus is also provided.)
- Pulse control Electromagnetic Diaphragm (EMD) provides quick and
accurate aperture control for optimal auto exposure performance.
- Extremely compact and lightweight lens, particularly when considering
its near 5X zoom ratio and IS mechanism.
- Advanced optical system features internal focusing design with six moving
lens groups controlled by a patented Super Inner Cam mechanism for compact size, faster AF and excellent image quality at all distance settings.
- Aspherical lens element preserves sharpness and color clarity from edge to edge.
