300mm · f/2.8
The Sony 300mm F2.8 G SSM II is a professional telephoto prime with solid build and weather sealing. Optically, it offers excellent transmission, distortion, and vignetting control, but sharpness at f/2.8 is only 'good' on high-resolution sensors and lags behind rivals like Canon's 300mm f/2.8L IS II. The autofocus is fast and accurate, though it may hunt in low contrast. It lacks in-lens stabilization, relying on camera body IS. Best suited for users on 24MP cameras or those prioritizing smooth bokeh and robust handling over ultimate resolution.
