Canon EF 40mm f/2.8 STM Lens Review

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.

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

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.
