Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L)

The Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L) is a full-frame zoom lens with a constant f/1.8 aperture, offering prime lens sharpness and clarity throughout its range. This innovative lens features fast and precise autofocus, a constant 30cm minimum focusing distance, and a stable inner zoom mechanism for easy handheld or tripod use.

  • Full Frame | f/1.8 to f/16
  • Superfast Wide-to-Normal Zoom
  • HLA Autofocus

Its lightweight design, weighing less than 1kg, and versatile 82mm filter size ensure portability without compromising quality. Built to withstand the elements, this lens also includes advanced coatings to minimise flare and ghosting, an HLA motor for near-silent focusing, and two customisable AFL buttons for versatile capturing.

Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L)

The Sigma 28-45mm f/1.8 DG DN Art Lens (Leica L) is the world's first full-frame zoom lens with a constant maximum aperture of f/1.8, delivering sharpness and clarity comparable to that of a prime lens. Already the pioneer of unique, large-aperture zoom lenses Sigma introduces another fast, portable and versatile tool to its Art lineup.

In addition to its unprecedented brightness, the Sigma 28-45mm f/1.8 DG DN | Art delivers sharpness and clarity comparable to that of a prime lens throughout its entire zoom range. Also equipped with fast and precise AF and superior operability, this innovative optic turns a new page in the history of zoom lenses and their creative possibilities. It is a lens that will inspire full-frame film-makers, while bringing unparalleled versatility to stills photographers.

Constant maximum aperture of f/1.8

Once a privilege reserved only for prime lenses, the maximum f/1.8 aperture allows full-frame camera users to expose hand-held in low light and produce beautiful bokeh, while enjoying the flexibility of a zoom. This unique optical achievement has been created through Sigma's accumulated optical design experience and advanced production technology.

Practical and stable inner zoom

Employing an inner zoom mechanism, the overall length of the lens remains constant when the focal length or focus distance changes. This means the lens is easy to use when shooting hand-held, highly stable when mounted on a tripod or gimbal, and more resistant to dust and water contamination.

Consistent close focus

The minimum focusing distance is a constant 30cm across the entire zoom range, with a maximum magnification ratio of 1:4 at the telephoto end, providing excellent close-up shooting capabilities. As well as offering precise focus in confined spaces, the lens can therefore be used close to a subject without affecting sharpness when using the zoom.

Premium build at a lighter weight

By rights, such a fast zoom should be big and heavy, but while the lens’ rigidity and durability protect its sophisticated optical design, this is achieved at a weight of less than 1kg. What’s more, this reliable photographic tool uses a versatile filter size of φ82mm, meaning no compromise in portability or convenience.

The pinnacle of optical quality in a zoom

Through the effective arrangement of 5 SLD elements and 3 aspherical elements, aberrations are rigorously corrected. Axial chromatic aberration, which is particularly noticeable with large-aperture lenses, has been thoroughly suppressed, and the lens delivers clear images with minimal colouration, from sharply focused details to large, smooth bokeh.

Suppression of focus breathing

When using regular lenses, the angle-of-view can change as focus moves from near to far, affecting precise composition. With the Sigma 28-45mm F1.8 DG DN | Art this focus breathing is suppressed, enabling natural focus pulls when shooting video.

Minimal flare and ghosting

Flare and ghosting, which reduce image quality, have been largely eliminated using advanced simulation technology, ensuring the lens renders rich, high-contrast results in all conditions. In addition, in order to keep flare and ghosting to a minimum, the lens uses Sigma’s Nano Porous Coating and Super Multi-Layer Coating, producing superior resistance to backlighting and enabling clear, saturated images in all lighting conditions.

Faster focus with a linear motor

The lens’ AF mechanism uses an HLA (High-response Linear Actuator) to combine accelerated focusing speed with exquisite precision. And because the motor is near-silent it allows video recording without noise.

Precise and comfortable manual focusing

To deliver delicate and accurate manual focus, the lens employs a bi-wire driven focus ring with optimum torque setting, high resolution and an adjustable rotation angle between 90° and 720°*. This allows film-makers to pull focus with organic smoothness, and photographers to focus manually with outstanding accuracy.

Aperture ring refinements

The lens is equipped with an aperture ring as well as an aperture ring click switch and an aperture ring lock switch, allowing for aperture operation suitable for various shooting situations.

Equipped with two AFL buttons

Located on the side and on top of the barrel, two customisable AFL buttons can be easily reached in either horizontal or vertical shooting positions.

Built to withstand the elements

In addition to a dust- and splash-resistant body, the frontmost surface of the lens is coated with a water- and oil-repellent coating so that it can be used safely even in harsh outdoor environments.
