The SIGMA 28-45mm F1.8 DG DN has been specially developed for mirrorless cameras and delivers outstanding optical quality comparable to that of fixed focal lengths. It also offers fast autofocus and innovative features .
As a pioneer in the development of unique high-speed Zoom lenses such as the SIGMA 18-35mm F1.8 DC HSM Art or the SIGMA 24-35mm F2 DG HSM Art, SIGMA now introduces another fast, handy and versatile lens
.The SIGMA 28-45mm F1.8 DG DN Art is characterized not only by its unparalleled speed, but also by a sharpness and brilliance that is comparable to that of a fixed focal length lens over the entire focal length range. Equipped with fast and precise autofocus and outstanding operability, this innovative lens opens up a new page in the history of Zoomlenses and their creative possibilities. This lens will inspire filmmakers and photographers while offering unparalleled versatility
.SIGMA has succeeded in developing the world's first* full-frame Zoomlens with a maximum aperture of F1.8. The SIGMA 28-45mm F1.8 DG DN Art has an internal zoom mechanism, a closest focusing distance of 30cm over the entire focal length range and a filter diameter of 82mm. Despite its advanced features, the lens weighs less than 1kg, making it a versatile option for use with gimbals or handheld.
*As of June 2024 according to SIGMA research
Once a privilege of fixed focal lengths, the maximum aperture of F1.8 allows users of full-frame cameras to work handheld in low light conditions and create attractive bokeh. At the same time, they can now enjoy the flexibility of a Zoomlens.
Thanks to the internal zoom mechanism, the overall length of the lens remains constant when the focal length or focus changes. The SIGMA 28-45mm F1.8 DG DN Art is therefore easy to handle when shooting hand-held. When mounted on a tripod or gimbal, the internal zoom also ensures perfect balance.
In addition,this design is less susceptible to dust and splash water.
The close-up limit is 30cm over the entire Zoom range with a maximum magnification of 1:4 at 45mm focal length. This enables excellent close-ups. Regardless of the focal length, the lens offers consistently high imaging performance at the close focusing distance and precise focusing
.Fast Zooms are large and heavy. That was once the case. The SIGMA 28-45mm F1.8 DG DN Art combines a sophisticated optical design in a sturdy and durable housing. And it doesn't even weigh 1 kg. Thanks to the standard filter diameter of 82mm, filmmakers and photographers have access to an extensive selection of shooting filters such as ND filters or polarization filters.
SIGMA has attached great importance to meticulously correcting optical aberrations over the entire Zoom range. As a result, the SIGMA 28-45mm F1.8 DG DN Art can compete with fixed focal lengths in terms of sharpness and brilliance. Thanks to advanced lens coatings, the lens produces clear images without flares and ghosting, even in backlighting, while the optical design effectively suppresses focus breathing.
effective arrangement of 5 SLD elements and 3 aspherical elements rigorously corrects optical aberrations. Axial chromatic aberration, which is particularly noticeable with fast lenses, has been thoroughly suppressed in the SIGMA 28-45mm F1.8 DG DN Art. The lens delivers clear, sharp images with the finest details and a pleasantly creamy bokeh outside the focal plane.
With many lenses, the angle of view changes when focusing, which makes precise image composition difficult. The optical design of the SIGMA 28-45mm F1.8 DG DN Art effectively suppresses this focus breathing.
Flares and
, which impair image quality, have been optimized for all lighting conditions using the latest simulation technology. In addition, SIGMA uses Nano Porous and Super Multi-Layer lens coatings on this lens to prevent flares and ghosting as far as possible.
The SIGMA 28-45mm F1.8 DG DN Art offers a range of professional functions that are just as impressive as its outstanding optical performance. The fast and precise autofocus, the robust, weather-resistant construction, an aperture ring with "de-click function", smooth manual focusing and two AFL buttons make it a versatile photographic tool.
HLA motor (High-Response Linear Actuator) of the SIGMA 28-45mm F1.8 DG DN Art combines high focusing speed with maximum precision. Thanks to its virtually silent operation, it is barely audible even when shooting video.
Precise and sensitive manual focusing is extremely important when filming. Precise manual focusing is also very important in photography. The optimum torque of the focus ring in combination with the adjustable angle of rotation* between 90° and 720° offers the best possible support here.
*Only in combination with compatible cameras of the L-mount system.
Many demanding users appreciate the ability to set the aperture directly on the aperture ring of the lens. The SIGMA 28-45mm F1.8 DG DN Art therefore offers an aperture ring. Thanks to its "de-click function", this feature is also interesting for filmmakers, as the aperture can be adjusted smoothly and silently in this position. Those who prefer to set the aperture on the camera body can use the aperture ring's lock function and are protected against accidental adjustment.
The lens has two AFL buttons, which have been positioned for optimum accessibility when shooting in portrait and landscape format. These buttons can be assigned individual functions with compatible cameras*.
*Only in combination with compatible cameras. The available functions may vary depending on the camera used.
addition to the dust- and splash-proof housing*, the front lens of the lens has a water- and oil-repellent coating. This means you can take pictures without worrying even in difficult shooting conditions.
*The lens is dust and splash-proof, but not waterproof.
The specially adapted LH878-06 lens hood is included with the SIGMA 28-45mm F1.8 DG DN Art. This is securely locked in place with a quick twist and can be attached to the lens upside down for space-saving storage
