Sigma 28-45mm F1.8 DG DN Art for Sony E Mount
Description / Sigma 28-45mm F1.8 DG DN Art for Sony E Mount
◻ The world's first zoom lens with a constant F1.8 aperture for 35mm full-frame mirrorless camera systems.
◻ 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 lens, it 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 prime 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 performance.
◻ 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 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 well-balanced design. The click/declick 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 videos out in the elements.
◻ As a DG DN Art lens designed specifically for full-frame mirrorless camera systems, the SIGMA 24-70mm F2.8 DG DN II | Art is built with dust and splash-resistant structure, water and oil-repellent coating on the front lens element, and durable brass bayonet mount; along with click/de-click and lockable aperture ring, and AFL button and AF/MF switch.
