Rokinon AF AF 45mm f/1.8 45mm
The 86g weight and f/1.8 aperture of this 45mm full-frame lens provide a distortion-free alternative to 35mm optics with exceptional sharpness across the frame. The 9-blade diaphragm yields expressive sunstars and smooth bokeh, and the Linear Stepping Motor ensures quick, quiet autofocus. Street photographers and travel shooters on Sony E-mount will find this lens ideal for discreet, low-light work with its lightweight build and natural perspective.
