The 75-300mm f/4.5-5.6 Alpha A-Mount Telephoto Zoom Lens from Sony is designed for cropped ASP-C image sensors, and when used on these camera bodies its focal length becomes the 35mm equivalent of a 112.5-450mm telephoto zoom. This lens is constructed of 13 elements in 10 groups which combine to deliver sharp, clear photos throughout the zoom range. It has a minimum focusing distance of 4.9' and a front-end filter diameter of 55mm.
Its aperture varies depending on the focal length you choose, and will gradually increase from f/4.5 to f/5.6, or f/28 to 32, as the chosen focal length increases. It also has 7x circular aperture blades that work to produce smooth, out of focus background effects.
