G Master super-telephoto zoom
A 100 mm to 400 mm zoom range is ideal for sports, wildlife and similar subjects, with image quality and AF performance that support professional working needs.
Fast, tenacious autofocus
An optimal combination of double linear motor and DDSSM (Direct Drive SSM) drive systems achieves quick response, high accuracy, and tenacious tracking.
High resolution and fast AF at any focal length
Precision G Master optics ensure consistently high corner-to-corner resolution at any focusing distance throughout the lens’ zoom range.
Compact, lightweight and mobile
Innovative modular exterior construction and magnesium components reduce weight and size for improved portability and mobility.
Outstanding shooting versatility
A floating focus mechanism achieves a minimum focus distance of just 3.22 ft. (0.98 meters) so you can track and shoot subjects at any distance with one lens.
Lens Configuration
G Master lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background bokeh.
