The 28-75mm f/2.8 Alpha A-Mount Standard Zoom Lens from Sony covers a wide range of focal lengths from wide angle to medium telephoto, and has a constant aperture of f/2.8 over its entire zoom range. This makes it particularly valuable for depth-of-field control and using ambient light.
It is constructed of 16 elements in 14 groups - four of them being aspherical glass elements - which all help to deliver sharp, clear photos throughout the zoom range. It has a minimum focusing distance of 1.25' and a front-end filter diameter of 67mm.
