Features
A unique and indispensable addition to Canon’s series of EF lenses, the new EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance. The EF 40mm f/2.8 STM’s unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance. Its diminutive design is complemented by features such as a newly developed stepping motor for smooth and quiet continuous AF while capturing video with the Canon EOS Rebel T4i DSLR, a circular aperture (7 blades) for beautiful soft-focus backgrounds, and a short minimum focusing distance of only 0.98 ft./0.30 m.
The EF 40mm f/2.8 STM is Canon’s first EF pancake lens with a fixed focal length of 40mm and wide f/2.8 aperture, making it ideal for photographers who want a versatile, compact and lightweight lens for portrait, reportage, travel or landscape situations. Precision control over the circular, seven-blade aperture is enabled by the EMD, producing a beautiful bokeh effect and an aspheric lens with Super spectra coatings ensures optimal image quality from the centre of the lens to the periphery for stunning shots of practically any subject.
