Viltrox AF 56/f1.4 M is an APS-C prime portrait lens with an equivalent focal length of 90mm for Canon EOS M series cameras, featuring great sharpness and nice bokeh, Eye-AF supporting, and USB upgrade. It's a great choice for portraiture, landscape or architecture shooting, etc.

The short telephoto focal length pairs with a bright f/1.4 maximum aperture to help achieve notable control over depth of field and also benefits working in difficult lighting situations. The optical design incorporates extra-low dispersion and high refractive index elements, too, to reduce various aberrations and distortion for high clarity, color accuracy, and sharpness.

Complementing the optics, the lens's design also incorporates an STM stepping motor that affords fast, near-silent, and accurate autofocus performance along with full-time manual focus override. An internal focusing design also contributes to quick performance. Additionally, the lens features an integrated micro-USB port for making future firmware updates to the lens.
