Viltrox Air AF 25/1.7 Z 25mm
Weighing only 170g with a bright f/1.7 aperture and quiet STM autofocus, this 25mm prime offers a natural 37.5mm equivalent field of view ideal for daily carry. It delivers solid portrait and low-light performance for its price tier, though landscape sharpness is a noted weakness. Best for vloggers and street photographers wanting a lightweight, affordable walkaround lens for compact X-mount bodies.
