The companion for Sigma’s highly regarded 28-70mm f/2.8 compact zoom adds an unbroken range down to 16mm while retaining a small c. 77x100mm size, 72mm filter fit, and 450g weight. It is announced today and will be available to buy from June 17th for £749.99 (UK SRP) or $899 (US retail before tax).
The full-frame Sigma 16-28mm f/2.8 DG DN Contemporary offers a promise of exceptional optical quality with a faster constant maximum aperture in barrel size similar to existing f/4 16-35mm designs. Special attention has been given to field curvature correction for edge-to-edge sharpness, important in wide-angle views – this is enabled through the use of a built-in lens profile, correcting distortion and vignetting in-camera or during raw image processing.
It uses five FLD (fluorite-like glass) elements and four aspherics to minimise chromatic and off-axis aberrations. The lens has an inner zoom mechanism that keeps overall length and the centre of balance constant, improving performance when zooming during a gimbal take. The 72mm filter thread is larger than the 67mm of the similarly light and small 28-70mm f/2.8 DG DN Contemporary.. At just 100.6mm long (L-mount version) and 450g it’s appealing for outdoor, social, street and travel photographers who want a lightweight outfit for day-long use.
The lens is constructed using aluminium and thermally stable polycarbonate, performing well in temperatures from the arctic to the equator, and has a dust and splash resistant mount. AF uses a proven stepper motor compatible with high-speed AF, DMF and AF or MF modes with an MF switch on the side. It focuses down to 25cm with a maximum image scale of 1:5.6, 0.17X and has a nine-blade rounded aperture. On the L-mount version only, linear and non-linear focus ring behaviour can be set using the USB Dock UD-11.
The lens is supplied with front and rear caps and a bayonet mounted petal lens hood. Sigma WR or WR Ceramic,WR UV and WR Circular Polarising 72mm filters are optional extras.
