Canon has unveiled the latest addition to its leading EF lens range – the new EF-S 55-250mm f/4-5.6 IS STM. Designed to be compact, lightweight and versatile, the EF-S 55-250mm f/4-5.6 IS STM provides an incredibly flexible 55–250mm focal range that’s the perfect companion for photographers that want to get closer to their favourite subjects. The new model is the first EF-S telephoto zoom lens to feature Canon’s advanced STM technology, alongside a 3.5-stop optical Image Stabilizer, providing outstanding stills and movie quality throughout the entire zoom range.
Superior image quality, near and far
The EF-S 55-250mm f/4-5.6 IS STM is the ideal lens for photographers looking to extend the reach of their current kit. The additional zoom range it offers allows users to shoot a range of scenes and subject types, from beautiful portraits at 55mm, to distant wildlife at 250mm, with a single compact lens.
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. Offering fluid continuous focus tracking when shooting movies of moving subjects, STM also provides clean and natural focus transitions when focus shifts from one subject to another. Audio on movie footage can also be accurately captured, without the intrusion or distraction of focusing noise from the lens, thanks to the near-silent STM mechanism.
World class optical technologies and professional design
The EF-S 55-250mm f/4-5.6 IS STM incorporates a new design, featuring Canon’s industry-leading optical Image Stabilizer technology. The 3.5-stop advantage over non-IS models helps protect against the effects of camera shake – which are more exaggerated when shooting handheld with a telephoto zoom lens – making it easier for photographers to capture crisp and striking images in all conditions.
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, ensuring images are as sharp and clear as they appear to the human eye. Canon’s optimised Super Spectra Coating also minimises internal reflections, as well as ghosting and flare.
The redesigned lens now incorporates a non-rotating front element, ensuring a consistent effect when a filter is attached to the front of the lens. Weighing just 375g the EF-S 55-250mm f/4-5.6 IS is incredibly compact and lightweight – making it easy to carry around whilst on holiday or at family events.
