Sony's Sonnar T* FE 55mm f/1.8 ZA Lens is a standard focal length prime lens that features a fast aperture in a compact, streamlined design. Offering a 82.5mm comparable APS-C focal length, its f/1.8 aperture is bright and quick, which allows you to capture more light and confidently shoot in dimly lit or tough lighting conditions. Sony applied a Carl Zeiss T* anti-reflective coating. This works to combat the effects of ghosting and flares and leads to greater contrast and color fidelity.  This lens creates a 42.9 degree angle of view, a 1.64-feet focal length and accepts 49mm filters. 

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. Linear motor driven internal focusing is smooth and quiet, and a dust and moisture resistant design ensures consistently reliable performance.

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 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.

Better Image Quality

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.

Outstanding Color and Contrast

The ZEISS T* coating is an important contributing factor, effectively suppressing spurious reflections that can degrade overall image quality. Flare and ghosting are reduced for enhanced color and contrast that give images a deep, three-dimensional feel.
