This standard prime lens with a 55mm focal length and large F1.8 maximum aperture offers stunning ZEISS Sonnar contrast and resolution for full-frame E-mount bodies. It can also create gorgeous background bokeh to set off your subject when needed.

ZEISS and Sony technology in a precision optical design with the T* coating reduce all forms of aberration while achieving outstanding image-wide sharpness and contrast. State-of-the-art optical design and a 9-blade circular aperture add up to beautifully smooth bokeh with natural-looking highlights for deep, dimensional images. A dust and moisture resistant design means that the lens will function smoothly and reliably in a wide range of conditions and challenging environments.
