The SIGMA 500mm F5.6 DG DN OS | Sports is a prime ultra-telephoto lens designed specifically for mirrorless cameras. It has a 500mm focal length and offers exceptional image quality while compact and lightweight. The lens incorporates multiple large-diameter, exclusive, low-dispersion glass elements, allowing SIGMA to significantly reduce the lens size without using diffractive optical elements. Despite its compact size, the lens maintains the high resolving power expected from a 500mm prime lens. The lens body is primarily made of high-precision engineering plastic parts, ensuring excellent build quality and weather resistance, including a dust and splash-resistant structure. With its descriptive power and compact size, the SIGMA 500mm F5.6 DG DN OS | Sports provides a new photographic experience for wildlife, aviation, sports, and other fast-action photography.

High optical performance and compact lens construction

The newest optical design has dramatically reduced the size of the optical system for a 500mm ultra-telephoto lens. By using particular low-dispersion convex elements at the front of the lens, the lens provides both high aberration correction capability and a short overall length. The high level of production technology at SIGMA’s only manufacturing base, the Aizu factory, ensures the precise processing of the exclusive low-dispersion glass elements with a large aperture. The lens effectively corrects all aberrations, mainly axial chromatic aberration, which cannot be corrected by the camera body, ensuring a stable high resolution from the centre to the periphery of the image.
