A compact, lightweight comprehensive zoom From 24mm to 105mm and F4 aperture throughout the zoom this high-performance G Lens offers consistently high image quality. In addition to outstanding optical performance it features compact, lightweight design for portability and mobility befitting the E-mount system. Fast, precise AF and high reliability add to the broad utility of this fine zoom lens. Excellent corner-to-corner imaging throughout the zoom range Advanced optics achieve consistently high corner-to-corner resolution throughout the zoom range. Four aspherical elements effectively reduce aberration, while ED (Extra-low Dispersion) glass elements minimize chromatic aberration. A circular aperture and carefully controlled spherical aberration shape add expressive potential with beautiful, smooth background bokeh and natural highlights that complement outstanding in-focus sharpness and clarity. A one-lens solution for mobile, versatile shooting Excellent optical performance and a high zoom ratio are packed into a compact, lightweight only 663 grams (23.4 oz.). The compact lightweight design extend to E-mount bodies for outstanding system mobility and handling ease. This one high-performance lens lets you shoot a wide range of subjects and situations. A minimum focus distance of 0.38 meters (1.25ft.) and built-in optical image stabilization further enhance all-around versatility. Constant F4 and fast, precise, quiet AF for stills and movies A bright constant F4 maximum aperture throughout the zoom range keeps the brightness even when focal length is changed. Sony’s Direct Drive SSM (DDSSM) AF drive system offers fast, precise, quiet focusing. And a precision optical design minimizes focus breathing. All of this makes the FE 24-105mm F4 G OSS an excellent choice for both stills and movies. Professional reliability and operability A fluorine coating on the front element prevents contaminants such as oils, grime, and water from sticking to the front of the lens, and makes them easier to remove if they do become attached to the lens surface. A dust and moisture resistant design1 and customizable focus hold button further contribute to professional operability and reliability.
