Viltrox Air AF 25mm f/1.7 Air E 25mm
The f/1.7 maximum aperture and 9-blade diaphragm create distinct subject separation in a 170g body, making this an unusually portable low-light prime for APS-C cameras. Its leadscrew-type STM motor delivers quiet, reliable autofocus, while the HD Multilayer Nano Coating and ED element suppress flare and chromatic aberration at an accessible price point. This lens is best for street photographers and beginners who want a fast, lightweight 37.5mm-equivalent walk-around lens without the bulk or cost of premium alternatives.
