Canon EF 40mm f/2.8 STM Pancake Lens

Product information

Switch between candid portraits, relaxed snapshots and vivid filming all without changing your lens. Fast, smooth focus and an adaptable focal length that balances angle and range make this lens an essential addition to any Canon user’s arsenal.


  • 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.
  • Fast, accurate autofocusing ensures pin-sharp images even in tough conditions. The Movie Servo AFM with STM uses stepping-motor technology for smooth, quiet autofocus when filming on compatible Canon DSLRs.
  • 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.
  • 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.
  • For use with EF mount Canon DSLR cameras

Q & As

Canon EF 40mm f/2.8 STM Pancake Lens 5 5 1 1
Amazing and Fun! This lens is great for when you want a light and quick lens to take out with you when doing street photography. You hardly notice there is a lens on the camera it is so light and because it is a panckae lens you dont feel as if you are intruding when taking photographs out and about. The lens is great fun and gets you back to the basics in photography allowing easy experimentation with different photographic techniques. I wopuld recommend this lens to anybody starting out in photography or those looking for a quiet and light lens for use away from a studio. 05 August 2014
