The 28-200mm F2.8-5.6 is the first*1 all-in-one zoom lens for full-frame mirrorless cameras to offer a maximum aperture of F2.8. It maintains outstanding performance throughout the entire zoom range, and aperture values of F3.5 at 50mm, F4.5 at 100mm, F5.6 at 200mm. From landscape photography to portrait photos and snapshots, the 28-200mm F2.8-5.6 delivers finely detailed images in a wide range of shooting situations. The generous use of special LD and XLD lens elements (with properties close to those of fluorite) enables it to thoroughly minimize chromatic and other aberrations, while the application of BBAR (Broad-Band Anti-Reflection) Coating offers high anti-reflective benefits and reduces ghosting and flare that are otherwise likely to occur when shooting backlight scenes. Additionally, by leveraging camera functionality*2, the lens delivers excellent optical performance to match the high-resolution image sensors on the latest cameras, achieving beautiful images that are a cut above all-in-one zoom lenses of the past.
