The Sigma 300-600mm F4 DG OS | Sports lens redefines the capabilities of a 600mm F4 prime lens, offering the flexibility to zoom out to 300mm without any compromise on optical performance. Its innovative inner zoom mechanism ensures that the centre of gravity remains stable throughout the zoom range, making it an exceptionally versatile and user-friendly tool for capturing a wide range of scenes with unmatched clarity and ease.
Exceptional Optical Performance
Equipped with 28 lens elements in 21 groups, including six FLD (F Low Dispersion) and one SLD (Special Low Dispersion) glass elements, as well as anomalous dispersion and high-refractive index glass, this lens delivers remarkable optical clarity. It effectively corrects chromatic aberrations and other distortions, maintaining prime-lens-level sharpness and detail across the entire zoom range.
High-Speed Autofocus & Advanced Optical Stabilisation
Ultra-Fast HLA-Driven Autofocus
Despite its large F4 aperture, the lens features a lightweight focusing lens group, thanks to its High-response Linear Actuator (HLA) motor. Combined with advanced glass materials and optimised optical power distribution, this allows for lightning-fast autofocus with pinpoint accuracy, ensuring you never miss a decisive moment.
5.5-Stop Optical Stabilisation with OS2 Algorithm
Sigma''s advanced OS2 algorithm delivers 5.5 stops of optical stabilisation at 600mm, powered by a precision-engineered actuator and sensor system. Users can choose between two stabilisation modes:
- Mode 1: Ideal for general still photography and video shooting.
- Mode 2: Specially designed for panning shots, stabilising motion in horizontal, vertical, or diagonal directions, ensuring smooth and accurate tracking of moving subjects.
Robust, Lightweight & Well-Balanced Design
Premium Magnesium Alloy & Carbon Fibre Construction
The lens barrel is crafted from magnesium alloy, ensuring durability while keeping weight to a minimum. Additionally, the carbon fibre hood enhances portability without sacrificing robustness. The lens''s optical design strategically shifts the centre of gravity closer to the camera, reducing front-heavy weight distribution for improved handling.
Thermal Insulation Coating for Outdoor Performance
A specialised thermal insulation paint on the lens body minimises heat absorption from sunlight, ensuring stable performance even during prolonged outdoor shoots in bright conditions, making it ideal for nature, sports, and wildlife photography.
Innovative Function Ring for Extended Control
The newly integrated function ring expands the lens''s versatility, offering two distinct modes:
Focus Preset Mode: Instantly shift focus to a pre-set position by turning the function ring left or right—ideal for capturing repeated shots at a fixed focal point.
Power Focus Mode: Enables smooth and controlled focus shifts at a constant speed, perfect for video recording and precise manual focusing during handheld shooting. The focus speed can be adjusted in two steps, depending on the ring''s rotation angle.
Durable & Precision-Engineered Tripod Mount
The tripod socket is designed with a bearing-based rotating mechanism, ensuring durability and smooth rotation. It includes an optional click/de-click system for precise angle adjustments at 90° increments. The Arca-Swiss compatible foot can be removed or replaced with alternative tripod sockets (available separately) for greater customisation.
Drop-In Filter Holder for Enhanced Creativity
The drop-in filter holder accommodates standard ø40.5mm filters, including Sigma''s newly developed drop-in circular polarising filter and a variable ND filter, which allows for adjustments of up to 7 stops—both available separately.
Dust- & Splash-Resistant Build for All-Weather Performance
As part of Sigma''s Sports line, this lens features a comprehensive dust- and splash-resistant structure, protecting all essential components such as:
- Mount joints
- Manual focus ring
- Zoom ring
- Custom switches and exterior controls
Additionally, the front element is coated with a water- and oil-repellent layer, making maintenance easier by preventing dust, dirt, and water droplets from adhering to the surface.
The Ultimate Choice for Professional Photographers
The Sigma 300-600mm F4 DG OS | Sports lens is a game-changer for photographers demanding superior image quality, high-speed autofocus, and unmatched stabilisation in an ultra-telephoto zoom lens. Whether you''re capturing wildlife, sports, aviation, or action photography, this lens delivers professional-grade performance in any shooting environment.
