The SIGMA 28-45mm F1.8 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.
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.
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.
The minimum focusing distance is a constant 30cm across the entire zoom range, with a maximum magnification ratio of 1:4, 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.
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.
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.
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.
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.
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.
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.
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.
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.
