Viltrox AF 56mm f/1.7 Air (APS-C)
A solid beginner-tier APS-C portrait prime, the 56mm f/1.7 Air is an 85mm-equivalent that weighs just 171g, making it an easy first portrait lens for kits like the X-T30, X-M5, Z50 II, or a6700. The featherweight build and bright aperture are the draw. It has no weather sealing, so it's not for harsh-condition shooting, and its APS-C image circle rules out full-frame bodies.
