Product description from Canon

At launch 2012 Canon wrote this regarding Canon EF 40mm F2.8 STM:

"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.

Standard and medium telephoto

A versatile, compact pancake lens. A fast maximum aperture enables low-light shooting and depth-of-field control. STM provides smooth quiet autofocus when shooting video with compatible cameras.

Never be without your EOS. The compact pancake EF 40mm f/2.8 STM is very thin, so you’ll always be able to take your DSLR with you.

Smooth and quiet AF, STM focussing for movies
Fast, accurate autofocusing ensures pin-sharp images even in tough conditions. Movie Servo AF with STM uses stepping-motor technology for smooth, quiet autofocus when filming on compatible Canon DSLRs.

Useful low light shooting
An f/2.8–22 aperture range provides control over depth of field, giving you the freedom to restrict or extend focus as required. A fast maximum aperture allows hand-held shooting in low light without using flash.

Great image quality designed for travel versatility
A versatile 40mm focal length is great for travel. Tackle everything from portraits to landscape and street photography. Great image quality right across the frame, thanks to an aspherical lens design and Super Spectra coatings."


Compatibility, autofocus and focal length

This lens is constructed to fit all models of Canon cameras, regardless of camera model or type of sensor.

The ability to use autofocus is available for all cameras.

The lens has a focal length of 40 mm. Depending on which camera the lens is used, the experienced and perceived focal length will be different. Please visit the list of compatible cameras below, it will provide the equivalent focal length you get on each camera.

Lens brightness and image stabilizer

The lens brightness and aperture value is f/2,8.

This aperture value indicates that the lens is very bright.  This will make it so much easier shooting in darker environments where you do not want or can use flash lighting, for example in churches or at different sports venues.

The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds. Since the lens is bright, with good aperture value, the lack of image stabilization might not be that big of a deal, although a image stabilizer is always an advantage to have.

Filter and Lens Hood

The lens has a traditional filter thread on the front and its measuring 52 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.

There is a lens hood that fits the lens (model name "ES-52") but unfortunately this is something that is not included when purchasing the lens and must be ordered and bought separately, as an accessory.
