Viltrox AF 50/2 Z 50mm
Its 205g build and STM motor deliver fast, quiet autofocus with eye detection in a full-frame f/2.0 prime that creates smooth bokeh and excellent low-light capability. The 13-element optical path (including ED and aspherical glass) and weather-sealed metal mount with USB-C updates provide sharp, reliable performance across the frame. This lens is ideal for Sony E-mount portrait and street photographers who demand a lightweight standard prime with natural perspective and minimal focus breathing for video.
