Sigma 28-45mm f/1.8 DG DN ART Lens for Leica / Panasonic L-Mount

Sigma 28-45mm f/1.8 DG DN ART Lens

Experience the world's first full-frame mirrorless zoom lens with a constant F1.8 aperture, the Sigma 28-45mm F1.8 DG DN ART. This innovative lens offers exceptional sharpness and clarity, rivaling that of prime lenses, making it a groundbreaking addition to Sigma's renowned Art lineup.

Unprecedented Brightness and Clarity

The Sigma 28-45mm F1.8 DG DN ART lens stands out with its unprecedented brightness, delivering sharpness and clarity across the entire zoom range. It features fast and precise autofocus (AF) and superior operability, revolutionizing zoom lenses and their creative possibilities. Ideal for both full-frame filmmakers and still photographers, this lens offers unparalleled versatility.

Constant Maximum Aperture of F1.8

With a constant F1.8 aperture, this lens allows for hand-held shooting in low light and produces beautiful bokeh, typically reserved for prime lenses. This optical achievement is a result of Sigma's advanced design and production technology, crafted in Aizu, Japan.

Practical and Stable Inner Zoom

Featuring an inner zoom mechanism, the lens maintains a constant length regardless of focal length or focus distance changes. This design ensures ease of use when shooting hand-held, stability on tripods or gimbals, and increased resistance to dust and water.

Consistent Close Focus

The lens boasts a minimum focusing distance of 30cm throughout the zoom range, with a maximum magnification ratio of 1:4 at the telephoto end. This allows for excellent close-up shooting capabilities, maintaining sharpness even when used close to the subject.

Premium Build at a Lighter Weight

Despite its fast aperture, the Sigma 28-45mm F1.8 DG DN ART remains lightweight, weighing less than 1kg. It combines rigidity and durability, utilizing a versatile filter size of φ82mm without compromising on portability or convenience.

Exceptional Optical Performance

Meticulous correction of optical aberrations throughout the zoom range ensures clarity and definition comparable to prime lenses. Advanced coatings minimize flare and ghosting, producing clear images even in challenging lighting conditions. Focus breathing is also suppressed, enhancing the lens's expressive power for both photography and filmmaking.

High-Speed AF and Innovative Features

The lens's AF mechanism utilizes an HLA (High-response Linear Actuator) for accelerated focusing speed and precision, remaining near-silent for video recording. It also offers delicate and accurate manual focusing, thanks to a by-wire driven focus ring with optimal torque setting and high resolution.

Aperture Ring and Customizable Buttons

An aperture ring with a click switch and lock switch provides versatile aperture operation for various shooting scenarios. Two customizable AFL buttons on the barrel ensure ease of access in both horizontal and vertical shooting positions.

Durable and Weather-Resistant

Built to withstand harsh outdoor environments, the lens features a dust- and splash-resistant body and a water- and oil-repellent coating on the frontmost surface. Additionally, a petal-type hood with a locking mechanism is included, which can be reversed for convenient storage.
