The Sony FE 55mm f1.8 ZA Carl Zeiss Sonnar T* Lens is the ideal choice for portraiture, low-light work, travel and general purpose photography. This dust and moisture resistant E-mount lens offers a bright f1.8 maximum aperture which provides a natural, bokeh effect for out-of-focus subjects.
Sony's FE lenses are primarily designed for Sony's full-frame E-mount compact system cameras, such as the A7 and A7R, but will also work with the Sony NEX cameras.
