The TTArtisan AF 56mm F1.8 is a compact autofocus portrait lens designed for APS-C cameras. With an 84mm full-frame equivalent focal length, it is well suited to portraits, detail work, and subject separation. The fast f/1.8 aperture helps maintain usable images in lower light while producing a naturally shallow depth of field for background blur.

Autofocus is driven by an STM + lead screw motor system, designed to provide smooth, quiet focusing suitable for both stills and video. The optical design uses 10 elements in 9 groups, including ultra-low dispersion and high-index glass elements to help control chromatic aberration and improve overall clarity.
