Bring your photography to the next level with the Sigma 50-100mm F1.8 DC HSM Art Lens for Nikon F. This innovative mid-range zoom lens, a successor to the groundbreaking Sigma Global Vision 18-35mm F1.8 DC HSM Art Lens, offers prime lens-like results with exceptional brightness and resolution throughout the zoom range. Designed with the APS-C image circle of 1.5x in mind, the 50-100mm F1.8 lens covers three popular short tele prime focal lengths: 85mm, 105mm, and 135mm. This makes it an incredibly versatile tool for photographers, catering to a wide range of shooting scenarios. The lens maintains a constant F1.8 aperture, ensuring consistent image quality and light intake, a feature that videographers will find particularly useful. It also maintains focus as the lens is zoomed, providing a seamless transition between focal lengths. The Sigma 50-100mm F1.8 DC HSM Art Lens incorporates Sigma Art Line Image Technology Innovation. It features three FLD (F Low Dispersion) glass elements, one SLD (Special Low Dispersion) glass element, and one high-refractive index, high-dispersion glass element to minimize aberrations and maximize image clarity. The lens also boasts a redesigned and enhanced Hyper Sonic Motor, which is 30% slimmer and provides fast and accurate autofocus. The durable polycarbonate diaphragm is made with fluorine and features blades with a carbon feather film for exceptionally smooth operation, even during continuous shooting. With its inner focusing and zoom design, this lens offers versatile shooting options. It also includes a tripod socket for stable and comfortable operation. The lens features 21 elements in 15 groups, a minimum aperture of F1.6, an 82mm filter thread, and a minimum focus distance of 37.4 inches. Sigma Global Vision lenses, including the new 50-100mm F1.8 DC Art, can be updated with the latest lens software from a workstation or laptop using the Sigma Optimization Pro software and Sigma USB Dock (sold separately). Every Sigma lens undergoes rigorous testing and evaluation using Sigma's proprietary A1 MTF (modulation transfer function) measuring system. This ensures that even the most elusive high-frequency details are within the scope of Sigma's quality control inspections. As a result, every Global Vision lens, including the 50-100mm F1.8 DC Art, is A1 tested, analyzed, and approved before leaving the factory, guaranteeing maximum performance right out of the box.
