Sigma announce four new lenses


Sigma has announced three new additions to their Art range of lenses: the 14mm F1.8 DG HSM | A, the 24-70mm F2.8 DG OS HSM | A and the 135mm F1.8 DG HSM | A. They have also announced the release of a 100-400mm F5-6.3 DG OS HSM C lens.


135mm F1.8 DG HSM | A

As the sixth full-frame prime lens to join Sigma’s Art lens series, the 135mm F1.8 extends the line-up into the telephoto range. 

The ultra-bright 135mm F1.8 DG HSM | A is designed for ultra-high megapixel DSLRs and a strong compression effect will allow photographers to establish a variety of dramatic perspectives while delivering a beautiful bokeh effect.

Inside a large hypersonic motor delivers a fast autofocus speed and an acceleration sensor detects the orientation of the lens allowing the autofocus system to respond to varying loads on the focusing group due to gravity.

Specification: Lens Construction: 13 elements in 10 groups | Minimum aperture (width): F16 | Filter size: ø82mm | Angle of view (35mm): 18.2° | Minimum focusing distance: 87.5cm./34.4in. | Dimensions (diameter x length): ø91.4mm x 114.9mm/4.0in. x 4.5in. | Number of diaphragm blades: 9 (rounded diaphragm) | Maximum magnification ratio: 1:5 | Weight: 1,130g/40.2oz.


14mm F1.8 DG HSM | A

Sigma describes this lens as the ‘worlds first and only F.18 ultra-wide-angle lens’. Chromatic aberration sometimes seen on shots taken with wide-angle lenses is minimised by three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements.

The lens features a large 80mm aspherical front lens element, developed from the Sigma 12-24mm F4 DG HSM | A, that minimises distortion and offers excellent peripheral brightness.

The 14mm F1.8 DG HSM | A is the seventh prime lens to join the Sigma Art series.

Specification: Lens Construction: 16 elements in 11 groups | Minimum aperture (width): F16 | Angle of view (35mm): 114.2° | Minimum focusing distance: 27cm./10.6in. | Dimensions (diameter x length): ø95.4mm x 126mm/9.5in. x 5.0in. | Number of diaphragm blades: 9 (rounded diaphragm) | Maximum magnification ratio: 1:9.8 | Weight: 1,170g/41.3oz.


24-70mm F2.8 DG OS HSM | A

This all-new Sigma 24-70mm F2.8, the fourth generation of the family, promises to ‘deliver the performance and functionality’ that photographers demand from this workhorse lens. 

The aspherical lens element is thicker at the centre than at its edges, which Sigma says helps it achieve extremely high-resolution images.

A newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds

The lens barrel is designed for high-rigidity, with thermally stable composite external moving parts and a dust and splash-proof mount with rubber sealing, all of which help this lens perform well in challenging conditions.

Specification: Lens Construction: 19 elements in 14 groups | Minimum aperture (width): F22 | Angle of view (35mm): 84.1-34.3° | Minimum focusing distance: 37cm./1.5in. | Dimensions (diameter x length): φ88mm×107.6mm /3.5in. x 4.2in. | Number of diaphragm blades: 9 (rounded diaphragm) | Maximum magnification ratio: 1:4.8 | Weight: TBD


100-400mm F5.6-6.3 DG OS HSM | A

This new lightweight telephoto lens, weighing in at just 1160g, yet features everything you'd expect such as an optical stabiliser (OS), hypersonic motor (HSM) with updated algorithm for fast autofocus and a focus limiter.

Photographers will be able to use a new push/pull mechanism in add to the regular twist mechanism for quick control of the angle of view.

Four SLD (Special Low Dispersion) glass lens elements help to minimise any optical aberrations and an acceleration sensor detects camera shake and allows the OS to stabilise the image regardless of whether the camera is being held in vertical or horizontal orientation.

The Nikon-mount version also includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body for stable Auto Exposure (AE) performance during continuous shooting

Specification: Lens Construction: 21 elements in 15 groups | Minimum aperture (width): F22 | Filter size: 67mm | Angle of view (35mm): 24.4-6.2° | Minimum focusing distance: 160cm./6.3in. | Dimensions (diameter x length): ø86.4mm x 182.3mm/3.4in. x 7.2in. | Number of diaphragm blades: 9 (rounded diaphragm) | Maximum magnification ratio: 1:3.8 | Weight: 1,160g/ 40.9oz

All four of the lenses come in Sigma, Nikon and Canon mounts. Release dates are to be confirmed, but we'll let you know as soon as we find out.
