As we’ve already mentioned, a 50mm lens works really well for portraiture on an APS-C format body. Any of the EF-mount lenses on test will suit an APS-C format DSLR, or an EOS M-series mirrorless camera via a mount adapter. For a native EF-M mount lens, our favourite is the Sigma 56mm f/1.4 DC DN | C, which gives an effective focal length of 89.6mm, coupled with a fast f/1.4 aperture rating.
