Viltrox AF 56/1.7 Z 56mm
Delivering an 85mm full-frame equivalent field of view, the bright f/1.7 aperture and 4 ED elements provide strong subject separation and control over optical aberrations. Its featherlight 171g build makes it an unobtrusive choice for all-day carry without sacrificing the STM autofocus performance. This lens is best for APS-C Sony shooters seeking an affordable, travel-friendly portrait prime.
