Description
Exceptional quality, functionality and features of the flagship of the Sigma’s Sports line
Combines high robustness and mobility
The lens barrel is made of magnesium alloy for the main parts and the hood is made of carbon, achieving both high robustness and light weight. In addition, the optical design with the center of gravity toward the camera greatly improves the weight balance, which tends to be front-heavy.
Thermal insulation paint for perfect lens performance
The exterior of the lens body is coated with a thermal insulation paint that effectively suppresses heat absorption from sunlight. This prevents the lens from heating up, even during long outdoor shoots in sunny weather, such as nature or motorsports photography.
New function ring adds extended functionality
The Sigma 300-600mm F4 DG OS | Sports features a newly added function ring that further expands the options of the lens. The focus ring offers two different modes, selected via its setting switch:
Focus Preset Mode:
By turning the function ring to the left or right, the focus can be instantly shifted to a pre-registered focus position. This is useful when frequently shooting at a fixed focus position.
Power Focus Mode:
Focusing at a constant speed is possible by operating the function ring.
This allows for smooth focus shift during movie shooting as well as for focusing with minimal movement when shooting hand-held. Focusing speed can be changed in two steps depending on the angle at which the function ring is operated.
Durable and easy-to-handle tripod socket
The tripod socket’s rotating mechanism uses bearings for both high durability and smooth rotation with an optional click/declick mechanism for each 90° angle to assist in accuracy. The tripod socket foot is compatible with Arca-Swiss type clamps, but can be easily removed and replaced with different interchangeable tripod sockets (available separately) to suit a variety of situations and preferences.
Equipped with a drop-in filter holder
The Sigma 300-600mm F4 DG OS | Sports features a drop-in filter holder for standard ø40.5mm filters. In addition, Sigma has developed a new drop-in circular polarizing filter and a variable ND filter (available separately) that can be adjusted by approximately 7-stops while dropped into the lens.
Weatherability of Sigma’s Sports line specifications
The mount joints, manual focus ring, zoom ring, custom switches and other control switches, and exterior joints are all protected from dust and splash by a dust- and splash-resistant structure. Further, the frontmost surface of the lens is coated with a water- and oil-repellent coating to facilitate maintenance when water droplets or dust adhere to the lens.
Various functions to support shooting
The lens features a variety of buttons and switches to accommodate individual preferences and the demands of different shooting situations, including AFL buttons in four different locations, a focus mode switch, a focus limiter switch, an OS mode switch (Mode 1 or Mode 2), and a custom mode switch.
