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 centre 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 colour balance. A bright f/2.8 maximum aperture allows you to shoot under pretty much any lighting conditions, and the sophisticated lens configuration, including one aspherical element, guarantees high image quality from the centre to the edge of the frame. The optimized coatings used in constructing the lens greatly reduce ghosting and flare, and deliver superb colour balance.
The Canon EF 40mm F2.8 STM Lens is an awfully compact, fast, pancake lens that is part of the new STM family of Canon lenses. Incorporating the new Canon STM stepping-motor technology for quiet, accurate focus operation, the Canon 40mm f2.8 prime is great for capturing sharp photos that stand out whilst providing a professional and natural looking background blur. The Canon EF 40mm f2.8 STM Lens can be mounted on both full frame (EF) and cropped sensor cameras (EF & EF-S), when mounted onto a Canon camera with an APS-C sized sensor the field of view is equivalent to a focal length of about 60mm in 35mm format. The Canon EF 40mm f2.8 comes in a handy, lightweight package and is appropriate for a wide variety of subjects, from discreet portraits to landscapes.
