Rounded 7-Blade Diaphragm

This EF 40mm f/2.8 STM Lens from Canon is a welcome addition to Canon's line-up of EF lenses--a light, inconspicuous "normal" lens. At a featherweight 4.6 oz, this is one of the lightest lenses in the EF family. It's less than one inch long, so it will never draw unwelcome attention to you when you're shooting in public. 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 center to the edge of the frame. The optimized coatings used in constructing the lens greatly reduce ghosting and flare, and deliver superb color balance.

STM functionality provides quiet, smooth and continuous autofocus during video operation (continuous video autofocus only when used with the Canon EOS 70D, Rebel T4i and T5i). The circular aperture formed by 7 diaphragm blades combined with the wide aperture can give you beautiful bokeh--the out-of-focus background areas of your images. This 40mm lens will give you a view equivalent to 64mm when used on a camera with an APS-C sensor, and is able to focus as close as 11.81".

Newly developed STM technology for smooth and quiet continuous AF while shooting video (continuous video autofocus only supported with EOS 70D, Rebel T4i and T5i cameras).
Lightweight and unobtrusive 4.6 oz lens is less than one inch long.
Bright f/2.8 aperture is effective in low light situations and provides shallow depth of field focus control.
High image quality from the center to the periphery thanks to its advanced lens configuration including one aspherical element.
Optimized coatings that minimize ghosting and flare while providing exceptional color balance
A circular 7-blade aperture for beautiful soft-focus backgrounds
Short minimum focusing distance of only 11.81"
Mounted on a camera with an APS-C sensor, this lens offers a view similar to a 64mm lens in the 35mm format.

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.
