World's first F1.8 full-frame zoom

The SIGMA 28-45mm F1.8 DG DN Art is the first full-frame zoom lens to maintain a constant F1.8 maximum aperture throughout its range. Built for Leica L mount cameras, it targets photographers and filmmakers who need prime-level optical performance in a versatile zoom. An inner zoom mechanism keeps the barrel length constant for stable handling on gimbals or tripods. A High-response Linear Actuator motor drives fast, quiet autofocus.

Wide-angle range with constant aperture

The 28-45mm focal range covers wide-angle perspectives suited to environmental portraits, interiors and landscape work. Constant F1.8 aperture provides shallow depth of field and low-light capability across every focal length. Minimum focusing distance of 30 cm and 1:4 maximum magnification at 45 mm allow detailed close-ups without changing lenses. Optical design aims to minimise focus breathing during video recording.

Replaces multiple wide primes

This single zoom replaces a kit of fast wide-angle primes such as 28 mm, 35 mm and 45 mm equivalents, reducing bag weight and lens changes. The jump is worth it for shooters who regularly work between 28 mm and 45 mm at wide apertures and value consistent rendering. Buyers needing longer telephoto reach, macro magnification beyond 1:4 or a lighter variable-aperture zoom will not find those attributes here.

Questions about this item

Will the 28-45mm F1.8 DG DN lens mount directly on my Leica L-mount body without an adapter?

Yes, the lens uses the Leica L mount so it attaches natively to any L-mount camera body.

How can I confirm the inner zoom mechanism is functioning correctly after mounting the lens?

Rotate the zoom ring from 28 mm to 45 mm; the barrel should stay at a constant 12.4 in length with no extension or wobble.

Does the box include a 3.5 in filter thread protector or must I buy a front cap separately?

The lens ships with front and rear caps; the 3.5 in filter thread accepts standard screw-in filters but no protective filter is bundled.
