PRIME MEETS ZOOM
One of the best-loved wide-aperture crop-sensor standard zooms on the market, the SIGMA 18-35mm combines the optical performance and constant F1.8 aperture of a prime lens with the versatility of a zoom. With a full-frame equivalent focal length of 27-52mm, the lens has a wide-angle to a standard focal range, which makes it a highly versatile optic that can be used for a wide range of photo and video applications.
Its unusually wide aperture makes it easy to achieve a shallow depth-of-field, and easy to use hand-held in low light conditions. It’s considered by many film-makers as an absolutely must-have lens owing to its sharp optics, relatively compact size, F1.8 aperture, and fast and quiet AF. In addition, its inner focusing and inner zoom mechanisms, which keep the centre of balance relatively constant, make the 18-35mm ideal for use on a gimbal as rebalancing isn’t required when zooming.
