This powerful 24 - 105 mm G Lens with an F4 aperture throughout the zoom range offers consistently high image quality. In addition to outstanding optical performance, it features a compact, lightweight design that provides the premium portability and mobility that the E-mount system deserves. Four aspherical elements minimise distortion, while ED (Extra-low Dispersion) glass elements minimise chromatic aberration. A circular aperture and carefully controlled aberration shape provide more expressiveness with beautiful, smooth background bokeh and natural highlights that complement outstanding sharpness and clarity of focused areas. Despite excellent optical performance and a high zoom factor, the weight is only 663 grams (23.4 ounces). The compact, lightweight design also fits E-mount lenses for outstanding system mobility and ease of use. With this one powerful lens, you can capture a wide variety of subjects and situations in the picture. A constant F4 aperture throughout the zoom range ensures brightness even when the focal length is changed. The Direct Drive SSM AF drive system enables fast, precise, quiet focusing. All these features make the FE 24-105mm F4 G OSS an excellent choice for both photo and video recording. A fluorine coating on the front lens element prevents contaminants such as oil, dirt and water from accumulating on the lens. A dust- and moisture-resistant design as well as an individually adjustable focus hold button additionally contribute to professional reliability and operability.
