Standard prime

Sonnar T* FE 55 mm F1.8 ZA


  • Portrait

  • 55 mm focal length and large aperture in a "normal" prime lens with impressive ZEISS Sonnar T* contrast and resolution.
  • 35mm full frame format, a large F1.8 maximum aperture, and sophisticated design make this lens ideal for α7 and α7R bodies.
  • 9-blade circular aperture contributes to gorgeous bokeh.
  • Dust and moisture resistant design.

Renowned ZEISS contrast and resolution brings out the best in α7 and α7R full-frame E-mount bodies. The T* coating works with an innovative optical design to suppress internal reflections, for sublime contrast from highlights to deep blacks. In keeping with the Sonnar concept, a large F1.8 maximum aperture can produce beautiful full-frame background bokeh, but you also have the option of stopping down for extended depth-of-field. A bright lens like this is also an advantage when shooting indoors or outdoors in low light. Linear motor driven internal focusing is smooth and quiet, and a dust and moisture resistant design ensures consistently reliable performance.

* With interchangeable-lens digital cameras incorporating APS-C type image sensors.
When mounted on α series cameras with APS-C type sensors, the actual angle of view will be equal to the angle obtained at a focal length approx. 1.5 times longer than stated.
Less light is transmitted by any lens at the image periphery. If the light falloff becomes excessive, reduce the aperture by 1 or 2 stops.
