A new-generation Star-series lens, assuring high-contrast, high-resolution imaging even at image edges, and delivering clear, crisp images with minimal aberrations
This large-aperture standard zoom lens is the latest model of the new-generation Star (★) series, which is designed to provide the best possible image quality and accommodate the super-high-performance cameras of the future. Its newly designed optics assures greatly improved contrast and sharpness compared to previous models, while compensating various aberrations to a minimum and delivering sharp, clear images not only in the middle of the image field but at the edges. By incorporating one ED (Extra-low Dispersion) glass optical element, one anomalous dispersion glass optical element and two ED (Extra-low Dispersion) aspherical glass optical elements, it effectively minimizes chromatic aberration over the entire zoom range.
The newly designed zoom optics features a lighter, more compact focus-lens group. This focus-lens group is driven by an advanced PLM (Pulse Motor), which assures smooth, high-speed autofocus operation with minimized noise. A redesigned focus mechanism provides a minimum focusing distance of just 0.3 meters and a maximum magnification of 0.24 times, making this a handy lens for capturing all types of subjects — from everyday snapshots to close-ups and landscapes.
|This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are K-1 Mark II, K-1, K-3 Mark III, K-3 II, K-3, KP, K-70, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version.
If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure.
