Canon Announces another New Lens to the STM range of lenses

Canon has announced the release of the New Canon EF-S 55-250mm F4-5.6 IS STM LensCanon STM EF-S Lens 55-250

Canon introduced the new range of STM lenses back in 2012. These STM lenses (Stepping Motor lenses) allow for the capture of high-quality still and video images and reduce motor noise from the lens which is particularly important to Canon as they have a growing number of photographers and video enthusiasts utilizing DSLRs to not only shoot high-quality still images but video too.

New members to the Canon range of cameras that include video functionality namely the Canon Rebel T5i (700D), Canon SL1(100D) and the recently announced Canon, have very efficient auto focus and tracking in Live View Mode when paired with the new STM lenses. Being perfect companions the launch of the T5i and the SL1 saw these STM lenses being introduced as the new kit lenses.

Canon’s first lens in the Stepping Motor range was launched last year in the shape of the  EF 40mm f/2.8 STM, commonly referred to as a pancake lens due to its shallowness. This was followed with:

EF-S 18-55mm f/3.5-5.6 IS STM – Kit lens option for the Canon Rebel T5i, Canon SL1 and Canon 70D.
EF-S 18-135mm f/3.5-5.6 IS STM – Alternative kit lens.
EF-M 18-55mm f/3.5-5.6 IS STM – For use with Canon M Compact Systems Camera. 
EF-M 22mm f/2.0 STM
 – For use with Canon M Compact Systems.

and the New

EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens

This new 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.

Canon STM Lenses

The Canon EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens features one UD lens element, minimising chromatic aberration throughout the range of the zoom for outstanding image quality of 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.
