Canon today unveiled the new EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens. Incorporating a new design, the EF-S 55-250mm f/4-5.6 IS STM sports an optical formula comprising 15 elements arranged in 12 groups (including an ultra-low-dispersion lens element), with an improved close-focus point of 85m throughout its zoom range. The manufacturer's STM technology ensures the EF-S 55-250mm f/4-5.6 IS STM provides high-performance auto focus when capturing stills, and smooth, near-silent AF in movies with compatible cameras. The integrated optical image stabiliser promises to give users a 3.5-stop advantage over non-IS models. The Canon EF-S 55-250mm f/4-5.6 IS STM will be available from late September 2013 with an SRP of £349.99 / €419.99 / $349.99.
