SIGMA Corporation of America, the US subsidiary of SIGMA Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan) is pleased to announce the SIGMA 28-45mm F1.8 DG DN | Art lens. This is the world's first zoom lens with a constant F1.8 aperture for full-frame mirrorless camera systems. Available for Sony E-mount and L-Mount, this new wide-to-standard zoom spans several popular focal lengths from 28mm to 45mm, with image quality comparable to prime lenses.
The SIGMA 28-45mm F1.8 DG DN | Art was developed as a full-frame successor to the SIGMA 18-35mm F1.8 DC HSM | Art (for APS-C DSLR cameras), which in 2013 became the first lens in the world to achieve F1.8 throughout the entire zoom range.
While offering the convenience of a zoom, this new lens does not compromise on optical performance. By effectively arranging 3 aspherical lens elements and 5 SLD glass elements, this lens suppresses various aberrations and achieves performance comparable to single focal length lenses, even surpassing the SIGMA 24mm F1.4 DG DN | Art and SIGMA 50mm F1.4 DG DN | Art, which have an established reputation for their optical quality.
In particular, the 28-45mm F1.8 DG DN | Art focuses on suppressing axial chromatic aberration, which is often noticeable in large-aperture lenses, to achieve images with minimal coloration on both the focus plane and bokeh, and to demonstrate high optical performance from open aperture. The minimum focusing distance is 30cm (11.8 inches) throughout the entire range, and the maximum magnification ratio of 1:4 is achieved at the 45mm focal length.
Featuring internal zoom and HLA (High-response Linear Actuator) autofocus, and an optical design that minimizes focus breathing, the SIGMA 28-45mm F1.8 DG DN | Art is well-suited for video work, including gimbal setups, thanks to its balanced design. The click/de-click switch and lockable aperture ring are designed to suit a variety of personal capture preferences, and the dust- and splash-resistant design also makes it suitable for shooting stills and video out in the elements.
The SIGMA 28-45mm F1.8 DG DN | Art lens will be available for $1,349 through authorized retailers in the US in late June 2024.

[Key Features]
1. The world's first* full-frame, F1.8 maximum aperture zoom lens
SIGMA has successfully developed the world's first full-frame zoom lens with a maximum aperture of F1.8. The SIGMA 28-45mm F1.8 DG DN | Art incorporates an inner zoom mechanism, a minimum focusing distance of 30cm across the entire zoom range, and a filter size of φ82mm. Despite its advanced feature-set, the lens weighs less than 1kg, making it a portable and versatile option for either hand-held shooting or a gimbal setup.
Constant maximum aperture of F1.8
Once a privilege reserved only for prime lenses, the maximum F1.8 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 at the company's sole production base in Aizu, Japan.
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'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.
2. Excellent optical performance comparable to that of a prime lens
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 filmmakers 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.
3. High-speed AF speed and innovative features
The SIGMA 28-45mm F1.8 DG DN | Art delivers a range of professional features as impressive as its outstanding optical performance. With high-speed and adaptable AF, a durable weather-resistant structure, a de-clickable aperture ring, smooth manual focusing and on-barrel AFL buttons, all features combine to create a versatile photographic tool capable of responding to any situation.
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 bi-wire driven focus ring with optimum torque setting, high resolution and an adjustable rotation angle between 90° and 720°*. This allows filmmakers 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.
Includes locking petal-type hood
A petal-type hood is included to shield the lens from light. It has a locking mechanism for secure attachment and can be reversed for easier storage.
