Sony G Master SEL50F12GM 50mm
The f/1.2 aperture and 11-blade diaphragm deliver exceptionally shallow depth of field with smooth, rounded bokeh, while four XD Linear Motors provide fast, silent autofocus for both stills and video. Despite its bright design, the lens maintains a relatively portable 778g build with comprehensive weather sealing and a de-clickable aperture ring for seamless video operation. This lens is best for portrait photographers and wedding shooters who need uncompromising low-light performance and definitive subject separation.
