Sonnar<sup>®</sup> T* FE 55 mm F1.8 ZA

Fast F1.8 for broad creative control

Renowned ZEISS® contrast and resolution bring out the best in full frame image sensors such as those in the Sony α7 series, and a large F1.8 maximum aperture can produce beautiful full-frame background bokeh. You can also stop down for extended depth-of-field. A bright lens like this is also an advantage when shooting in low light.

Smooth bokeh enhances depth and dimension

A nine-blade circular aperture works with this lens's state-of-the-art optics to create beautifully smooth bokeh in out-of-focus background areas when desired, with natural-looking highlights that won't distract from the important foreground subject and details.

Sony and ZEISS® team up for better images

Advanced technology from ZEISS® and Sony combines in a precision optical design with three aspherical elements, two double-sided, that effectively reduce all forms of aberration while achieving outstanding image-wide sharpness and contrast. The ZEISS® T* coating suppresses internal reflections, for sublime contrast from highlights to deep blacks.

Shoot with confidence anywhere

Some of the most exciting images are captured in challenging environments. A dust and moisture resistant design means that the lens will continue to perform reliably in moderately wet or dusty conditions, so you can shoot with confidence wherever those great shots are found.
