Canon EF 40mm f/2.8 STM Lens Review

By on

The Canon EF 40mm f/2.8 STM pancake lens is the lightest lens along with the 50mm f/1.8 II in the EF family. Photography Blog has posted a review Canon’s full-frame F 40mm f/2.8 STM pancake lens.

The EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. This lens also includes an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance.

Below are the specifications of the EF 40mm f/2.8 STM lens from Canon.


Canon EF 40mm f/2.8 STM Lens Specs

  • Continuous Autofocus for Video With T4i
  • Bright f/2.8 Aperture
  • Lightweight 4.6 oz Lens
  • Unobtrusive–Less Than 1″ Long
  • Aspherical Element–High Image Quality
  • Optimized Coatings Reduce Ghost & Flare
  • Exceptional Color Balance
  • 7-Blade Diaphragm for Beautiful Bokeh
  • Close Focusing to 11.81″
  • 64mm Equivalent If Used on APS-C Camera

From the Photography Blog’s review:

Despite it’s mostly plastic construction and affordable price, the Canon EF 40mm f/2.8 STM build quality is reassuringly good, certainly better than some of Canon’s 50mm primes. It’s a great match for either a full-frame Canon DSLR like the EOS 6D or an APS-C body like the EOS 700D that we tested it with, where the focal length changes to 64mm.
