This lens, part of the esteemed Contemporary line, offers the unique opportunity to experience the thrill of shooting with a large-aperture F1.4 mid-tele lens. Its compact and lightweight design, coupled with outstanding image quality, makes it a standout in its class. This lens is the third addition to the series, following the standard 30mm F1.4 Dc Dn | Contemporary and the wide-angle 16mm F1.4 Dc Dn | Contemporary lenses. It provides the remarkable bokeh and brightness expected from F1.4 lenses, even in the mid-tele range, thanks to Sigma's cutting-edge technology. The lens name includes ""DC"", indicating its optimal performance on cameras with Aps-c image sensors. When used with a full-frame image sensor camera, some vignetting may occur. The ""DN"" in the name signifies its optimal performance on cameras with a short flange back distance. This lens is a member of the high-performance Contemporary line, featuring Sigma's latest technologies. It offers smooth Af, ideal for video shooting, and is compatible with the Sony E-mount Fast Hybrid Af for precise Af tracking. The lens also supports face recognition or eye Af functions of cameras, ensuring continuous focus on the face or the eye even if the subject moves during the shoot. The lens mount is dust and splash-proof, making it a reliable choice in various conditions. It features a high-precision, rugged brass bayonet mount for enhanced durability. The lens design considers the capabilities of the camera body function to correct peripheral light amount and distortion, resulting in a compact and lightweight construction without compromising on image quality. The lens is designed to minimize flare and ghosting, and Sigma's Super Multi-Layer Coating reduces these effects to help photographers produce sharp and high contrast images even in backlit conditions. The lens benefits from an open aperture of F1.4, achieving sufficient bokeh and brightness even with Aps-c size cameras. Its compact and lightweight body is perfect for daily use, capable of capturing various scenes ranging from portraits to snapshots, as well as night views. The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. This lens builds on the success of the 30mm F1.4 DC DN | Contemporary and the 16mm F1.4 DC DN | Contemporary lenses, making it a valuable addition to the Sigma DC DN Series for mirrorless cameras.
