Features
Canon has introduced a STM version of its EF-S 55-250mm, the EF-S 55-250mm f/4-5.6 IS STM. STM lenses has a stepping motor, which provides providing smooth and silent focusing in movie shooting. This STM version also features internal focusing. This means the lens barrel will not rotate during focusing. New lens will be avialbe in late September for $350. New Stepping Motor Lens is the Perfect Companion for the EOS 70D, EOS Rebel SL1, and EOS Rebel T5i Digital SLR Cameras. The new EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens. Created to be the perfect companion lens for the EOS 70D, EOS Rebel SL1 and EOS Rebel T5i Digital SLR cameras, the EF-S 55-250mm f/4-5.6 IS STM lens expands Canon’s line of Stepping Motor (STM) lenses to six models – the EF-S 18-135mm f/3.5-5.6 IS STM, the EF 40mm f/2.8 STM, EF-S 18-55mm f/3.5-5.6 IS STM, EF-M 18-55mm f/3.5-5.6 IS STM, EF-M 22mm f/2.0 and the new EF-S 55-250mm f/4-5.6 IS STM lens. Canon’s Stepping Motor lenses allow for the capture of high-quality still and video images and reduce motor noise from the lens so cameras, such as the new EOS 70D, will capture the sound of the video scene being recorded without the interruption of noise by the focusing motors.
The EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens offers high magnification in a compact and lightweight EF-S telephoto zoom lens with an Optical Image Stabilizer for up to 3.5* equivalent stops for shake correction. The lens’ stepping motor and newly-designed focus mechanism support Canon EOS Movie Servo AF (available on select EOS cameras) to provide smooth and quiet continuous autofocusing during video shooting, as well as when shooting photos.
The EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens features one UD lens element, reducing chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast. It features enhanced lens coatings to help ensure superb color balance while minimizing ghosting and flare and a 7-blade circular aperture creates beautiful, soft backgrounds. For outstanding performance, a new compact six-group zoom system provides a maximum magnification of 0.29x at the telephoto end. Full-time manual focus is available in AF mode. The front element does not rotate during focus, which is beneficial when using polarizing filters. Minimum focusing distance is 2.79 ft./0.85m. The lens’ rear focusing system, high-speed CPU and improved AF algorithm allow for high-speed autofocusing.
