The Sony FE 24-240mm f/3.5-6.3 OSS Lens for full-frame E-mount cameras. Able to cover everything from wide-angle to telephoto in a single compact form factor, this lens uses a variable aperture of f/3.5-6.3 to keep size and weight to a minimum. Ensuring maximum quality throughout the range the lens incorporates one extra-low dispersion element and five aspherical elements that combat various aberrations. Also, it has a linear autofocus motor and internal focus design that provides fast, accurate, and reliable focusing. The lens is dust and moisture-resistant as well, for operation in less-than-ideal conditions. And, it has a seven-blade circular diaphragm for smooth bokeh. A variable f/3.5-6.3 aperture helps keep lens size and weight to a minimum while still offering an outstanding 10x zoom range. Five aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
