Featuring a constant maximum aperture of f/2.8 across the entire 4.1x zoom range, the new lens makes a great choice for photographers wanting a general-purpose lens for regular use.

It is also compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF.
