Product Description
Premium Carl Zeiss Optics for Full Frame Excellence
The Sony Carl Zeiss Sonnar T* FE 55mm F1.8 ZA delivers renowned Carl Zeiss contrast and resolution optimized for α7 series full frame E-mount bodies. This fixed prime lens features the legendary T* coating that suppresses internal reflections for sublime contrast from highlights to deep blacks. With its 55mm focal length and bright F1.8 maximum aperture, this lens excels in both low-light photography and creating beautiful full-frame background bokeh.
Advanced Optical Design
Featuring a 5-group, 7-element optical design with advanced aspherical (AA) elements, this lens dramatically reduces spherical aberration while maintaining compact dimensions. The aspherical elements restore precise alignment of light rays at the image plane, ensuring high sharpness and contrast even at maximum aperture. The innovative internal focusing system powered by a linear motor delivers smooth, quiet autofocus operation.
Professional Build Quality
The 9-blade circular aperture design produces naturally rounded bokeh rather than polygonal shapes, creating more pleasing out-of-focus areas. A dust and moisture resistant construction ensures reliable performance in challenging conditions. The internal focusing design means the lens length remains constant, and the 49mm filter thread does not rotate—ideal for polarizing filter use.
Ideal for Portrait and General Photography
With a 43° angle of view (35mm equivalent) and minimum focus distance of 0.50m (19-11/16 inches), this lens is well-suited for portraits, street photography, and everyday shooting. The 14x magnification capability adds versatility for closer subjects. Stop down for extended depth-of-field or open up to F1.8 for dramatic subject isolation.
