With high levels of sharpness and clarity across the entire zoom range, you can achieve consistent results, whether shooting hand-held in low light or utilising the telephoto end of the zoom range. The lens excels in capturing details with close-up shots or shooting in small spaces thanks to a constant minimum focus distance of 30cm and a maximum magnification ratio of 1:4 at the telephoto end. With such versatile, high-powered performance, this 28-45mm lens would be an excellent addition to any photographer or filmmaker’s kit.

Advanced Construction for High-Quality Results

The 28-45mm f1.8 DG DN Art Lens features a premium construction of 18 elements in 15 groups, ensuring outstanding optical quality. With five Super Low Dispersion and three aspherical elements, it suppresses distortion and corrects axial chromatic aberration for clear images with minimal colouration. The lens also suppresses ghosting and flaring, using advanced simulation technology for colour-rich, high-contrast results in most shooting scenarios. Sigma’s Nano Porous coating and Super Multi-Layer coating further assist in minimising ghosting and flaring, ensuring clear, saturated images in various lighting conditions.

Accurate Manual and Auto Focusing for Video and Stills

To offer versatility for a range of creators, this 28-45mm f1.8 lens has a feature set that lends itself well to photography and video. Alongside producing detailed images, the lens offers rapid autofocus for capturing fast-moving subjects in stunning clarity. The lens’ AF mechanism uses an HLA (High-response Linear Actuator) to combine rapid focusing speed and high precision with a near-silent linear motor that will not disrupt your audio when filming. It also suppresses focus breathing for seamless focus pulls when shooting video to prevent the angle of view from changing with shifting focus. Photographers and filmmakers alike can enjoy smooth and accurate manual focusing with a bi-wire-driven focus ring with optimum torque settings, high resolution, and an adjustable rotation angle between 90 and 720 degrees.

Premium Build at a Lighter Weight

With such an advanced optical design, Sigma has created a lighter-weight lens with powerful abilities. The zoom lens weighs just 960g despite its fast aperture, providing excellent manoeuvrability for shooting on the move. This lightweight build is made more versatile by its thoughtful construction. With an inner zoom mechanism, the overall length remains constant when the focal length or focal distance changes, making it easier to shoot hand-held or mounted on a tripod or gimbal. The inner zoom ensures the lens retains balance for improved stability and enhanced resistance against dust and water contamination.

Durable, User-Friendly Design

Sigma’s 28-45mm f1.8 DG DN Art Lens has a durable, weather-resistant body with user-friendly features for straightforward operation. The dust and splash-resistant body with a water and oil-repellent coating on the front element lets you use the lens in various weather conditions. It also incorporates an aperture ring, an aperture ring click switch and an aperture ring lock switch, providing practical options for changing the aperture in any environment. For maximum accessibility, you can use two customisable AFL buttons on the side and the top of the barrel when shooting vertically or horizontally. A petal-type hood is included to shield the lens from excess light and has a locking mechanism for secure attachment. You can reverse the hood to store the lens safely.
