London, UK, 8 June 2012 – Canon today unveils two new compact, lightweight lenses - the EF-S 18-135mm f/3.5-5.6 IS STM and EF 40mm f/2.8 STM.
Showcasing a number of new features, including continuous autofocus in Movie mode, both models offer superior image quality and enhanced flexibility to enable photographers of all skill levels to capture both stills and movies of practically any subject.
Fast, accurate autofocus for film-makers and photographers
As well as offering full-time manual focus controls when shooting stills, the EF-S 18-135mm f/3.5-5.6 IS STM and EF 40mm f/2.8 STM are both also ideal for aspiring movie makers, allowing them to focus more accurately during shooting. The perfect companion lenses to the new EOS 650D, both models feature new stepper motor technology (STM), enabling fast, continuous focus when recording moving subjects - ensuring movies will be smoother and clearer than ever before.
Offering enhanced AF performance with high-speed, high-precision focusing, the two new lenses make it easy for photographers to capture more spontaneous shots, with exceptional detail and clarity. This is particularly useful for documentary, action or travel photography. With a minimum focusing distance of 0.39m and 0.3m respectively, the EF-S 18-135mm f/3.5-5.6 IS STM and EF 40mm f/2.8 STM allow you to get even closer to the action whilst keeping the subject in perfect focus.
Offering a focal range of 18–135mm, the EF-S 18-135mm f/3.5-5.6 IS STM has been created to offer photographers a compact, versatile zoom lens which can be used to capture a variety of subjects, from portraits to landscapes and action shots. Ensuring high-quality stills at slow shutter speeds, the EF-S 18-135mm f/3.5-5.6 IS STM features an intelligent optical Image Stabilizer which offers a 4-stop advantage over non-IS models. The lens will also sense whether the photographer is shooting normally or panning, engaging the most appropriate IS mode to capture the best possible image. When shooting movies, Dynamic IS automatically engages, countering any shake caused by the videographer's movement to produce smooth, stable footage.
For subtle background blur when exploring shallow depths of field in stills and movies, the EF-S 18-135mm f/3.5-5.6 IS STM features a circular aperture with an Electro Magnetic Diaphragm (EMD) which permits highly-accurate control over aperture settings. High image quality is also assured throughout the zoom range thanks to four groups of lens elements including one Ultra-low Dispersion (UD) and one Precision Molded Optics (PMo) element to counter chromatic aberration. Canon's optimised Super spectra coatings on each lens element also reduce ghosting and flare, ensuring images require minimal post-processing.
