Featuring a constant f/4 maximum aperture, this lens is well-suited for a variety of shooting scenarios while maintaining a slim and lightweight design for everyday use.
The optical construction includes a range of specialized elements—such as aspherical, extra-low dispersion, and high-refractive index components—that work together to reduce spherical aberrations, color fringing, and distortion, resulting in sharp, color-accurate images. Additionally, a ZERO (Zuiko Extra-low Reflection Optical) coating minimizes lens flare and ghosting, enhancing contrast and color fidelity in bright or backlit environments. For both photographers and videographers, the lens is equipped with a Movie & Still Compatible (MSC) autofocus system that delivers fast, smooth, and silent focusing.
It also features a close minimum focusing distance of 4.7" at the wide end and 9.1" at the telephoto end, along with a maximum magnification ratio of 0.25x, making it ideal for close-up work. The lens is built to withstand challenging conditions, with a dust-, freeze-, and drip-proof construction, ensuring reliable performance in various environments. A rounded seven-blade diaphragm contributes to a pleasing bokeh effect, adding to the lens's overall versatility and quality.
