Sony G Master SEL50F12GM 50mm
An f/1.2 aperture, 11-blade diaphragm, and Nano AR Coating II yield edge-to-edge sharpness and buttery bokeh, while four XD linear motors drive silent, instant autofocus. The weather-sealed magnesium barrel and a de-clickable aperture ring add durability and video-friendly control in a 778g body. Best for portrait and wedding shooters needing extreme low-light capability and dreamy backgrounds, and filmmakers who value smooth, quiet focus pulls.
