The Canon EF 28-135mm f/3.5-5.6 IS EF USM Lens is a compact and lightweight standard zoom lens that offers superior optical performance, plus a built-in Image Stabilizer. The IS system reduces the possibility of blurred photographs caused by camera shake, which allows for handheld photography in comparatively dim light without a flash or tripod. At the wideangle 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 faster and quieter AF operation, and the pulse control diaphragm (EMD) ensures precise aperture control.
Note! White Box merchandise comes supplied in a plain white box, instead of the manufacturer's colorful packaging. It is not a returned or refurbished item. It still includes all the manufacturer's accessories.
- 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 lens elements in parallel with the perceived movement.
- The internal focusing mechanism allows the front of the lens to remain stationary and to easily accommodate specialty filters, such as polarizing filters.
