EF 40mm f/2.8 STM

Product Info

A portable, versatile lens with STM for photographers travelling with their EOS.

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.

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.

Features

  • 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.
