Sigma’s unveils its first long telephoto zoom lens for full-frame mirrorless cameras

L-mount and E-mount photographers get affordable 100-400mm F5-6.3 DG DN OS zoom…

Full-frame mirrorless photographers can now go long without breaking the bank after Sigma released its first-ever big telephoto zoom lens for full-frame mirrorless cameras using the E-mount and L-mount fitments. The 100-400mm F5-6.3 DG DN OS is a versatile zoom that joins Sigma’s C (Contemporary) range and combines a lightweight offering with impressive features.

Tipping the scales at 1,135g (L-Mount) or 1,140g (E-mount), the 100-400mm F5-6.3 DG DN OS won’t weigh you down or fill up your kit bag and the versatile optic’s focal length will cover off everything from longer focal length portraiture to more typical sports and wildlife photography.

Built around a 22 elements in 16 groups design, the lens features a nine-bladed diaphragm and includes one FLD and four SLD elements to enhance image quality. The lens also employs a short minimum focusing distance, which gives a magnification ratio of 1:4.1, enabling photographers to capture frame-filling images of nearby objects.

Boasting a built-in image stabilisation (OS) system that offers four-stops of compensation to help keep images sharp (even when shooting in low light). The lens also features what Sigma call a ‘dual action zoom’ action, which as Sigma explains, means users ‘can zoom in or out by turning the zoom ring, or if preferred by pushing or pulling the lens hood, enabling fast intuitive adjustments to focal length.’

The 100-400mm F5-6.3 DG DN OS is compatible with Sigma’s USB dock that enables firmware updates to be added to the lens to future-proof its design. Using magnesium alloy to make for a strong lens mount, the design also incorporates polycarbonate to keep weight down and the lens can take a tripod collar for use on a tripod or monopod.

Other features include a customisable AFL button and the 100-400mm F5-6.3 DG DN OS is compatible with Sigma’s new TC-1411/TC-2011 1.4x/2x teleconverters for L-mount cameras to further extend the focal range on offer to photographers.

Available from July 10, the Sigma 100-400mm F5-6.3 DG DN OS is keenly priced, carrying a price-tag of £899/950.
