Canon EF 40mm f/2.8 STM Lens – Fixed
A unique and indispensable addition to Canon’s series of EF lenses, the 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 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.

Canon EF 40mm f/2.8 STM Overview
Characterized by its slim, pancake design, the EF 40mm f/2.8 STM from Canon is a sleek and versatile short-normal prime that is ideal for everyday, walk-around shooting. Its f/2.8 maximum aperture helps to realize its slim stature, and also suits working in difficult lighting conditions and offers control over depth of field for working with selective focus techniques. One aspherical element has been incorporated in the optical design, and helps to reduce distortion and spherical aberrations for high sharpness and clarity. A Super Spectra coating has also been applied, which helps to minimize lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, benefitting both photo and video applications, an STM stepping AF motor is used to realize quick, accurate, and near-silent autofocus performance.
Short normal-length prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 64mm equivalent focal length.
Modestly bright f/2.8 maximum aperture benefits working in low-light, affords control over depth of field, and helps to keep the overall physical design compact and lightweight.
Pancake form factor measures less than 1″ thick for an ultra-portable, versatile design.
One aspherical element limits distortion and spherical aberration in order to realize greater sharpness and accurate rendering.
Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
An STM stepping AF motor realizes smooth, near-silent autofocus that is complemented by a rear focus system, advanced AF algorithms, and a high-speed CPU for fast AF performance.
Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
