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 design2 and customizable focus hold button further contribute to professional operability and reliability.
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.
