Canon today unveils the latest addition to its leading EF lens range – the new EF-S 55-250mm f/4-5.6 IS STM.
The new model features a 3.5-stop optical Image Stabilizer and is the first EF-S telephoto zoom lens to feature Canon's advanced STM technology.
Canon's advanced STM technology ensures the EF-S 55-250mm f/4-5.6 IS STM provides high-performance autofocus (AF) when capturing stills, and smooth, near-silent AF in movies with compatible cameras.
The lens' new optical design includes 15 elements arranged in 12 groups, with an improved focusing distance of just 0.85m throughout its zoom range. An Electro Magnetic Diaphragm (EMD) with a circular aperture gives photographers fine control over aperture and smooth, blurred backgrounds, while an Ultra-low Dispersion (UD) lens tackles chromatic aberration. Canon’s optimised Super Spectra Coating also minimises internal reflections, as well as ghosting and flare.
The redesigned lens, which weighs 375g, now incorporates a non-rotating front element, ensuring a consistent effect when a filter is attached to the front of the lens.
The Canon EF-S 55-250mm f/4-5.6 IS STM will be available in the UK and Ireland from late September 2013 with an SRP of £349.99 / €419.99.
