Before you embark on your next photography adventure, consider the SIGMA 100-400mm F5- 6.3 DG DN OS Contemporary lens, a compact and lightweight ultra-telephoto zoom lens designed exclusively for full-frame mirrorless cameras. This lens offers remarkable optical performance, packing essential functionalities into a compact body for exceptional lightweight shooting, making it an ideal companion for field photography. The state-of-the-art optical design technology ensures edge-to-edge high-resolution and high-contrast image quality throughout its entire focal range. This lens achieves high image quality, rivaling that of standard zoom lenses such as the SIGMA 24-70mm F 2.8 DG DN Art, ensuring a perfect match with these lenses while shooting.
The level of bokeh and compression effect achieved by this ultra-telephoto lens provides a fresh perspective to ordinary everyday scenes. This combination of ultra-telephoto images with the excellent mobility of the SIGMA 100-400mm F5- 6.3 DG DN OS Contemporary will open up new ways for you to enjoy ultra-telephoto photography, from everyday snapshots to field photography and beyond. The lens construction comprises 16 groups and 22 elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions. Built on the latest optical design technology and optimized for mirrorless systems, this lens ensures the same high-resolution image quality all the way to the edges.
In addition to a high-speed and smooth AF enabled by the stepping motor optimized to the latest algorithm, the SIGMA 100-400mm F5- 6.3 DG DN OS Contemporary incorporates powerful image stabilization (OS) of four steps built into the lens. When combined with a camera body with image stabilization built in, the lens corrects for pitch and yaw axis rotations, providing even more powerful image stabilization. The SIGMA 100-400mm F5- 6.3 DG DN OS Contemporary supports straight zoom, which allows photographers to zoom in and out by adjusting the hood, enabling intuitive and quick view angle adjustments.
It features a "Dual action zoom" which supports both straight zoom and ring zoom. The lens is not merely about weight reduction, but it is durable, with careful selections to utilize the right materials in the right place. For instance, magnesium alloy is used for the part where a tripod socket is attached, which needs to be very strong. The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The SIGMA 100-400mm F5- 6.3 DG DN OS Contemporary lens is a testament to SIGMA's commitment to pushing the boundaries of lens technology, offering photographers a versatile, high-quality lens that is perfect for a wide range of shooting scenarios.
