A G Master telephoto for birds, wildlife and sport. The aperture does not change as you zoom, and with a teleconverter it reaches 800 mm.


The front element is too large for a normal filter thread, so the lens takes drop-in filters. A polariser or ND swaps in seconds, without removing the hood.

Advanced algorithms and improved tracking hold focus on the subject through a burst — on an α9 III body, up to 120 frames per second. Focus breathing and focus shift while zooming are suppressed, so the lens holds up on video too.
The ED XA element — extreme aspherical and extra-low dispersion at once — together with XA, Super ED and ED elements holds resolution across the whole zoom range. The bokeh stays what the G Master line leads you to expect.

The build assumes you shoot in all weather, not only on fine days.
The lens supports bursts up to 120 fps, active stabilisation and focus tracking even in 4K/120p slow motion.
