G Master 100-400 mm Super Telephoto

The Sony FE 100-400 mm f/4.5-5.6 GM OSS is a full-frame E-mount zoom from the G Master line. It covers a 100 mm to 400 mm focal range with a variable maximum aperture of f/4.5 at the wide end and f/5.6 at the long end. Optical SteadyShot image stabilisation and a double linear motor plus DDSSM autofocus system are built in.

Wildlife and Sports Shooters Seeking Reach

Professionals and serious enthusiasts who need a single lens for distant wildlife, field sports or aviation subjects will benefit from the versatile zoom range and fast, precise autofocus tracking. The 3.22 ft minimum focus distance and 0.35x maximum magnification add close-up flexibility. Photographers who require a constant f/2.8 aperture throughout the zoom range or a significantly lighter walk-around lens should consider other options.

77 mm Filter Thread Diameter

The front filter thread measures 77 mm, determining which circular polarisers, neutral-density filters or protective filters attach directly without step-up rings. This diameter is the key compatibility figure when buying accessories for the lens. The lens weighs 4.78 units as supplied.
