Extremely compact and portable design

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.
