Features Optically designed to draw out the maximum image quality of a flagship standard zoom lens In order to achieve best-in-class image quality, this fast standard zoom lens with a constant aperture of F2.8 consists of 17 elements in 12 groups. This includes three aspherical lens elements to control spherical aberration and distortion, and three ED glass lens elements to reduce lateral chromatic aberration (wide-angle) and axial chromatic aberration (telephoto). This allows the lens to achieve edge-to-edge sharpness across the entire zoom range. Nine rounded aperture blades create a smooth, circular bokeh. The suppression of spherical aberration to the ultimate extent contributes to produce beautiful bokeh at both the front and back. Applying Fujifilm’s unique HT-EBC (High Transmittance Electron Beam Coating) to the entire area of the lens surface ensures ghosting and flare are controlled for sharp, clear images. Using the newly developed Nano-GI (Gradient Index) coating technology which alters the refractive index between glass and air, ghosting and flare are effectively reduced for diagonal incident light. By combining this lens with an X Series camera body* with Lens Modulation Optimizer** (LMO) technology, the performance from the lens is improved even further. LMO corrects for diffraction*** to produce images with edge-to-edge sharpness and create a realistic three-dimensional effect, even at small apertures High-speed, quiet auto focus thanks to the Linear Motor By reducing the weight of the focus lens and mounting the Twin Linear Motor, high-speed, quiet AF is possible. Combine this lens with an X Series camera body* offering Phase Detection AF and the fastest AF speed of 0.06 seconds is available, making your photo shoots smoother and more efficient. With the near-silent shutter sound, photos can be taken discreetly in quiet locations. Weather resistant, dust-resistant and -10??C low-temperature operatio
