Wishing for a New STM Lens? Canon Announces the 55-250mm f/4-5.6 IS STM
If you’ve early-adopted to Canon’s new STM motors, then you’ve probably been wishing there were a few more lenses available that you could make use of. Canon is releasing new STM lenses at a steady pace, and today announced the 55-250mm f/4-5.6 IS STM, expanding the lineup of STM lenses to six total models. The new 70D will have STM compatibility, so this is certainly an area to keep an eye on.
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.
The EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens is scheduled to be available in late September for $349.99.
