We caught up with Sigma at their Photokina stand to get a closer look at their new lens releases

We got the announcement of three new Sigma lenses at the Photokina trade show this year, and now we’ve met them. Check out our video above to see what all the fuss is about.

Sigma 85mm f/1.4

Aimed at portrait photographers – and due out in November – key features include a 14-elements-in-12-groups build, including two elements made of SLD glass.

‘Elements made of SLD (Special Low Dispersion) glass and an optimized power distribution help minimise axial chromatic aberration,’ Sigma explains.

‘In the areas in front of and behind the point of focus, the optical system produces an attractive and natural bokeh effect by producing a smooth gradation of focus and minimising streaking.’

Sigma claims the 85mm f/1.4 is an excellent match for full-frame DSLRs of 50 million pixels or higher.

It will cost £1,199.99

Sigma 12-24mm F4 DG HSM | Art

The Sigma 12-24mm F4 DG HSM | Art features ⌀80mm large-diameter molded glass aspherical lens—the largest such element in this class of lens. With a constant aperture of f/4 through the zoom range and a minimum focusing distance of 24cm, the Sigma 12-24mm F4 DG HSM | Art has been designed to excel with the era of ultra-high resolution digital cameras.

The lens features lens elements made with FLD (“F” Low Dispersion) glass, which is equivalent to fluorite in performance, and an optimized power distribution.

Other points of interest are its newly designed Hyper Sonic Motor (HSM), which offers 1.3x the torque of its predecessor.

The lens mount incorporates rubber sealing to protect the mount from dust and water drops. The front and rear lenses also feature a water- and oil-repellent coating that is particularly useful when shooting in a drizzle, near ocean spray, and in a wide variety of other conditions.

The Sigma 12-24mm F4 DG HSM | Art will cost £1649.99, and we’re told we can expect it in October.

Sigma 500mm f/4 DG OS HSM

The new flagship lens in Sigma’s Sports lens series, the 500mm f/4 DG OS HSM will be available in Sigma, Canon and Nikon mounts.

The ‘dust and splash proof’ Japan-made newcomer features a magnesium-alloy barrel and incorporates two FLD elements, plus one SLD element.

Features also include a hyper sonic motor (HSM) designed to deliver fast and quiet AF.

‘With the further enhanced AF algorithm compared to previous models, continuous AF (AF-C) improves the focusing efficiency,’ Sigma claims.

The new 500mm lens will cost £5,999.99 and is expected to be made available in October.
