Sigma 300-600mm f/4 DG OS Sports Lens for L Mount Summary
The Sigma 300-600mm f/4 DG OS Sports Lens for L Mount is a professional super-telephoto zoom lens for full-frame L-Mount mirrorless cameras. It combines the reach and image quality of professional-level prime lenses with the versatility of a zoom, providing a constant f/4 aperture across the entire range. Despite being a zoom, the professional ‘Sports’ is able to gather lots of light and create beautiful subject separation.
The 300-600mm reach is ideal for subjects including sports, wildlife, and action, and it features HLA (High-response Linear Actuator) autofocus system for fast, precise AF, which maintains pace even with fast or erratic subjects.
Built-in optical stabilisation provides up to 5.5 stops of shake compensation, improving usability significantly at these longer focal lengths. An inner zoom mechanism also maintains a stable centre of gravity, which helps to make handling more predictable, whether shooting handheld or from a monopod.
Optically, the lens includes a combination of six FLD and one SLD element, which reduce aberrations and render extremely high-quality, and high-resolution results. Sigma has also included a 13-blade diaphragm, which produces beautiful smooth, natural bokeh, while the weather-sealed magnesium alloy barrel provides the confidence to shoot in poor conditions. A drop-in filter system supports polarising and variable ND filters, for additional creative control during outdoor content creation.
With professional image and build quality, fast autofocus, and a bright f/4 aperture throughout the zoom range, the Sigma 300-600mm f/4 DG OS Sports is a real alternative to fixed super-telephoto lenses for advanced enthusiasts and professional photographers, and is compatible with teleconverters for up to 1200mm reach when using the 2.0x.
Sigma 300-600mm f/4 DG OS Sports Lens for L Mount in More Detail
Exceptional Super-Telephoto Zoom Versatility
The Sigma 300-600mm f/4 DG OS Sports provides the advantages of a 600mm f/4 prime lens while allowing photographers to zoom out to 300mm without sacrificing optical performance. Its inner zoom design prevents weight shifts too, for stable handling. This makes it an ideal choice for sports and action photography, where subjects move unpredictably, and spontaneous reframing is often required.
Optical Performance That Rivals Prime Lenses
Sigma has created a zoom lens which meets the demands of professional sports and wildlife photographers, with optics that incorporate six FLD elements, one SLD element, and high-refractive index glass to reduce chromatic aberration and deliver edge-to-edge sharpness. Nano Porous Coatings (NPC) and Super Multi-Layer Coatings control reflections and lens flare, ensuring high contrast and accurate colour reproduction even in challenging backlighting conditions.
Powerful Optical Stabilisation Driven by the OS2 Algorithm
Sigma’s latest OS2 algorithm provides up to 5.5 stops of image stabilisation at the tele 600mm end of the zoom range, improving shooting in low light when handholding – albeit at 4kg this lens will often be tripod or monopod mounted. Two stabilisation modes are available:
- Mode 1 is optimised for general photography, balancing stabilisation with natural framing.
- Mode 2 is designed for panning shots, stabilising movement along any axis while allowing smooth tracking of fast-moving subjects.
High-Speed Autofocus with HLA Motor
Sigma’s tried-and-tested HLA (High-response Linear Actuator) motor enables exceptionally fast and precise autofocus while remaining near-silent, which is ideal for many telephoto subjects, from the sports field to wildlife sanctuary.
Despite its large f/4 aperture, the use of lightweight focusing elements ensures rapid, accurate AF performance, even for high-speed subjects.
Rugged Build with Professional Handling
The magnesium alloy body provides strength while keeping weight manageable, while a thermal insulation coating prevents the lens from overheating in direct sunlight, ensuring stable performance in heated settings.
Sigma’s Arca-Swiss compatible tripod mount features a smooth rotating mechanism with a click/de-click option at 90° stops, improving usability in both landscape and portrait orientations, while also providing broad compatibility and ease of use for various ballads, gimbals and tripods.
Drop-In Filter System for Creative Control
The Sigma 300-600mm f/4 DG OS Sports lens features a 40.5mm drop-in filter holder, which enables the use of drop-in circular polarisers and variable ND filters (available separately), giving photographers greater control in various conditions.
Weather-Sealed design
The dust and splash-resistant design protects against rain or harsh conditions and the front element is coated with a water and oil-repellent coating, which is far easier to clean and maintain.
Teleconverter Compatibility and USB Dock Support
The Sigma 300-600mm f/4 L-Mount version is compatible with and TC-2011 (2.0x) teleconverters, extending the focal length to 420-840mm f/5.6 and 600-1200mm f/8, respectively. Autofocus remains fully functional with either teleconverter, allowing photographers to accurately capture distant subjects across even greater distances.
For firmware updates and customisation, the lens also supports the USB Dock UD-11, enabling fine-tuning of autofocus, stabilisation modes, and function button.
