The Sigma 300-600mm F4 DG OS Sports lens pushes the limits of conventional zoom lenses, combining the flexibility of a zoom with the image quality expected from a prime lens. Covering a powerful 300mm to 600mm focal range, it helps photographers react quickly without changing lenses during crucial moments. With a high-speed HLA autofocus system and up to 5.5 stops of optical stabilisation at the long end, it is built to capture fast-moving action, from sport to wildlife.

Designed for professional use, this lens features a tough magnesium alloy body, thermal shielding, a customisable function ring, a sturdy tripod socket, and a practical drop-in filter holder for added creative control. The constant f/4 maximum aperture across the zoom range supports strong subject isolation and gives greater control over shutter speed, making it easier to freeze action.

The Sigma 300-600mm F4 DG OS Sports lens includes a versatile function ring with two modes: Focus Preset, which allows you to instantly return to stored focus positions, and Power Focus, which provides smooth variable-speed focus adjustments for video and handheld shooting.
