Sigma 28-45mm F1.8 DG DN for Sony E

After revolutionizing the world of photography with its innovative designs, the SIGMA 28-45mm F 1.8 DG DN | Art Lens emerges as the world's first full-frame zoom lens featuring a constant maximum aperture of F 1.8. This groundbreaking lens offers the sharpness and clarity typically associated with prime lenses, setting a new standard for zoom lens performance. As a pioneer in crafting unique, large-aperture zoom lenses, SIGMA continues to expand its Art lineup with this fast, portable, and versatile tool, ideal for both filmmakers and still photographers. The SIGMA 28-45mm F 1.8 DG DN | Art Lens boasts an inner zoom mechanism, maintaining a consistent lens length regardless of focal length or focus distance changes.

This design enhances stability during handheld shooting and when mounted on a tripod or gimbal, while also providing resistance to dust and water contamination. With a minimum focusing distance of 30cm across the entire zoom range and a maximum magnification ratio of 1:4 at the telephoto end, this lens excels in close-up shooting scenarios, ensuring precise focus and sharpness even in confined spaces. Weighing less than 1kg, this lens combines a robust build with lightweight convenience, making it an excellent choice for photographers on the go. Its Dia. 82mm filter size adds to its versatility without compromising portability.

The lens's optical performance rivals that of prime lenses, thanks to meticulous correction of optical aberrations throughout the zoom range. Advanced coatings ensure clear images even in challenging backlit conditions, while focus breathing is minimized, enhancing the creative possibilities for filmmakers and photographers alike. The lens's optical quality is further enhanced by the strategic placement of 5 SLD elements and 3 aspherical elements, effectively suppressing axial chromatic aberration and delivering images with minimal coloration and smooth bokeh. Advanced simulation technology has been employed to reduce flare and ghosting, with SIGMA's Nano Porous Coating and Super Multi-Layer Coating providing superior resistance to backlighting, resulting in rich, high-contrast images in any lighting condition.

Equipped with high-speed AF capabilities, the SIGMA 28-45mm F 1.8 DG DN | Art Lens features an HLA (High-response Linear Actuator) for rapid and precise focusing, with near-silent operation ideal for video recording. The lens also offers a bi-wire driven focus ring for smooth and accurate manual focusing, with adjustable rotation angles between 90 and 720 degrees, catering to both filmmakers and photographers. Additional features include a de-clickable aperture ring, an aperture ring click switch, and an aperture ring lock switch, allowing for versatile aperture operation. Two customizable AFL buttons are conveniently located on the lens barrel for easy access in both horizontal and vertical shooting positions.

Built to withstand the elements, the lens's dust- and splash-resistant body, along with a water- and oil-repellent coating on the frontmost surface, ensures reliable performance in harsh outdoor environments. A locking petal-type hood is included to protect the lens from stray light, enhancing image quality and offering secure attachment and easy storage.
