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.
