Standard focal-length range from wide-angle 24 mm to medium-telephoto 70 mm can effectively cover a wide variety of scenes and subjects with rendering performance that will change the perception of zoom lenses with a maximum aperture of f/4
Optical design that suppresses variations in aberrations from shooting distances of close-up to infinity, demonstrating sharp resolution even in the peripheral areas of the frame from the maximum aperture, and fine point-image reproduction
Achieved a minimum focus distance of just 0.3 m across the zoom range
Adoption of an ED glass element, an aspherical ED lens element, and three aspherical lens elements
Nano Crystal Coat adopted to suppress ghost and flare
Has the size needed to deliver an extremely high standard of optical performance, yet provides outstanding portability; employs a retracting mechanism that can be set on/off without pressing a button and reduces total length for a compact lens that can easily be taken anywhere
In consideration to a dust- and drip-resistance, the entire lens, including moving parts, has been sealed
