USED SIGMA 28-45mm F1.8 DG DN Art for Sony E

Product Features

• Achieves the world's first constant F1.8 aperture zoom lens for full-frame. This lens offers the abundant light and beautiful bokeh previously exclusive to prime lenses, now with the freedom of a zoom range for full-frame cameras. Enjoy the rich light intake and beautiful bokeh of a large F1.8 aperture across a versatile focal length range.
• Features an internal zoom mechanism. The lens's overall length does not change during zooming, making it easy to handle for handheld shooting and stable when used with a tripod or gimbal. This structure also helps prevent dust and water droplets from entering.
• Offers a minimum focusing distance of 30cm across the entire zoom range, with a maximum magnification ratio of 1:4 at the telephoto end, providing excellent close-up shooting capabilities. You can get close to your subject without worrying about changes in minimum focusing distance during zooming, making it ideal for tight shots or when you can't get far from your subject.
• Ensures the rigidity and durability essential for a reliable shooting tool, while sophisticated optical and mechanical design keeps the weight under 1kg and uses a versatile φ82mm filter size. No compromises on portability or convenience.
• Effectively corrects various aberrations by strategically placing five SLD glass elements and three aspherical lens elements. It thoroughly suppresses axial chromatic aberration, which is particularly noticeable in large-aperture lenses. This results in clear, color-accurate images, from the sharp in-focus plane to the beautifully blurred bokeh.
• Designed to minimize focus breathing. With minimal change in angle of view due to focus shift across the zoom range, it allows for natural focus transitions in video shooting.
• Advanced technology is used to combat flare and ghosting under all lighting conditions. Furthermore, Nano Porous Coating and Super Multi-Layer Coating are applied to suppress flare and ghosting to the absolute limit. This high resistance to backlight allows for clear, unobstructed shots in any lighting condition.
• Employs a High-response Linear Actuator (HLA) for the AF system, achieving high-speed AF with excellent drive precision. The quiet motor ensures noise-free video recording.
• The focus ring features a bi-wire system with optimal torque and high resolution, enabling delicate manual focus adjustments. Take advantage of the shallow depth of field at F1.8 for expressive focus pulls in video or for careful manual focusing.
• Equipped with an aperture ring. It also features an aperture ring click switch and an aperture ring lock switch, allowing for aperture control tailored to your shooting needs.
• Features two AFL buttons that can be assigned to custom functions. Placed on the side and top, they are easily accessible whether shooting horizontally or vertically.
• The dust- and moisture-resistant construction, combined with a water-repellent and oil-resistant coating on the front lens element, allows for confident shooting in challenging outdoor environments. (Designed with dust and moisture resistance in mind, but not waterproof.)
• Includes a petal-type lens hood with a locking mechanism for secure attachment.
