Canon EF-S 55-250 mm lens

Posted on

canon 55-250Canon’s new EF-S 55-250 mm f/4-5.6 IS STM zoom expands the company’s line of stepping motor (STM) lenses to six models. These lenses allow for the capture of high-quality still and video images and reduce motor noise from the lens so cameras will capture the sound of the video scene being recorded without the interruption of noise by the focusing motors.

The lens offers 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 55-250 features one UD lens element, reducing chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast, says Canon. It features enhanced lens coatings to help ensure superb colour 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 – beneficial when using polarizing filters.

Minimum focusing distance is 2.79 ft./0.85m.

Canon says the lens’ rear focusing system, high-speed CPU and improved AF algorithm allow for high-speed autofocusing.

The Canon EF-S 55-250 mm f/4-5.6 IS STM lens is scheduled to be available in late September for an estimated retail price of $399.99.
