Sigma’s award winning 16-28mm F2.8 is an ultra-wide-angle, wide-aperture zoom for full-frame mirrorless cameras. Combining outstanding optical performance with a constant F2.8 aperture, the lens is perfect for landscape, wedding, interior and architectural photography. Weighing in at 450g and measuring just 100.6mm in length, the lens is exceptionally portable, so is an attractive option for photographers wanting to travel light without compromising on optical quality. Optimised with the latest optical design technology, the 16-28mm is a high-performance optic that delivers exceptional sharpness across the frame with very little in the way of unwanted aberrations. An internal zoom mechanism keeps the overall length of the lens consistent throughout the entire zoom range, so that the lens’ centre of gravity stays fairly constant. This is perfect for gimbal use as it would not need adjusting when the focal length is changed. A filter thread around the front element makes attaching filters easy. The quality of this lens was recognised at the TIPA Awards and the AP Awards in 2023, where it won the Best Wide-Angle Zoom Lens and the Wide-Angle Zoom Lens of the Year awards respectively.
