Outstanding G Master Optical Performance

A sophisticated optical design featuring 22 elements in 16 groups uses ED and Super ED glass to deliver excellent resolving power while minimising optical aberrations. The result is impressive detail and clarity across the frame, making the lens well suited to demanding high-resolution Alpha camera bodies. :contentReference[oaicite:1]{index=1}

The bright f/4.5 maximum aperture also provides strong subject separation, while an 11-blade circular aperture helps produce smooth, natural-looking background blur and bokeh. :contentReference[oaicite:2]{index=2}

Whether you're tracking birds in flight, wildlife or sporting events, the focusing system is designed to keep pace with the performance of Sony Alpha camera bodies.

Autofocus performance is maintained when using compatible 1.4x and 2x teleconverters, allowing photographers to extend their shooting range while retaining high-performance AF operation. :contentReference[oaicite:3]{index=3}
