Sigma 100-400mm f/5-6.3 DG DN OS

State-of-the-art optical technology ensures very high-resolution results right to the edges of the frame, as well as high-contrast images throughout the entire focal range. A rounded diaphragm gives circular out-of-focus highlights, and Super Multi-Layer and Nano Porous coatings reduce flare and ghosting. The image quality rivals that of standard zoom lenses such as the SIGMA 24-70mm F2.8 DG DN | Art, ensuring a perfect match when used alongside these optics.

The bokeh effects and compressed perspective achieved when shooting at these longer focal lengths will open up a range of new shooting possibilities, allowing a fresh approach to everyday scenes. The lens is perfect for wildlife, action and portraits, and thanks to its short minimum focusing distance, which gives a magnification ratio of 1:4.1, it’s also ideal for capturing close-up subjects in stunning detail.

The lens brings to the table a range of advanced features including dual-action zoom, a customisable AFL button, focus throw angle adjustment (with USB Dock), a two-mode Optical Stabilizer, a tripod socket attachment and a focus limiter switch. The L-Mount version can also be used with two newly-developed teleconverters (1.4x and 2x), with full AF, for even longer focal lengths.

Whether you are considering investing in your first long lens, or are already a seasoned telephoto photographer, the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary is a robust, portable, ultra-telephoto zoom that offers superb image quality and excellent value for money.
