The NIKKOR Z 17-28mm f/2.8 is an ultrawide-angle zoom lens that covers the 17- to 28-mm range of focal lengths with a fast constant maximum aperture of f/2.8. This lens not only offers the excellent portability achieved with a total length of approximately 101 mm*1 and a weight of approximately 450 g, but also provides superior optical performance. Adoption of two ED glass, one Super ED glass, and three aspherical lens elements delivers stable resolution throughout the zoom range. The lens responds well to a variety of scenes and subjects for a broader range of expression utilizing the unique perspective afforded by an ultrawide-angle lens, as well as the fast f/2.8 maximum aperture and 0.19-m*2 minimum focus distance that enable dynamic expression to emphasize the primary subject. In an effort to make the lens easier to use with video recording, the NIKKOR Z 17-28mm f/2.8 is equipped with high-speed AF control that realizes smooth focusing, even with moving subjects, plus a stepping motor (STM) and control ring that achieve even quieter and smoother operation. The NIKKOR Z 17-28mm f/2.8 offers a fast constant maximum aperture of f/2.8 in a compact and lightweight body, yet is affordable. This ultrawide-angle lens is easy to carry around, both in town and while traveling, allowing users to enjoy expressing themselves through images as intended. Nikon will continue to pursue a new dimension in optical performance while meeting users' needs, contributing to the development of imaging culture, with the hope of expanding possibilities for imaging expression.
