About the product

The world's first* F1.8 full-frame mirrorless zoom

The SIGMA 28-45mm F1.8 DG DN | Art is the world's first full-frame zoom lens with a constant maximum aperture of F1.8, delivering sharpness and clarity comparable to that of a prime lens.

Already the pioneer of unique, large-aperture zoom lenses including the SIGMA 18-35mm F1.8 DC HSM | Art and the SIGMA 24-35mm F2 DG HSM | Art, SIGMA introduces another fast, portable and versatile tool to its Art lineup.

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’s 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.

With each optical aberration meticulously corrected throughout the zoom range, the SIGMA 28-45mm F1.8 DG DN | Art rivals prime lenses for clarity and definition. Thanks to its advanced coatings, the lens produces clear images, even in backlit environments, while focus breathing is thoroughly suppressed, bringing expressive power to film-makers and photographers.

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 coloration, 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’s 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 by-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.

* Only for L-Mount, and with compatible cameras.

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 customizable* AFL buttons can be easily reached in either horizontal or vertical shooting positions.

* Assignment of functions is limited to supported cameras and assignable functions vary depending on the camera.

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.

* The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.
