Sony Sonnar T 55mm F/1.8 ZA

This lens is designed for Sony digital cameras with the E-mount for shooting and creating professional-quality images. Every shot captures fine details and outstanding colours. The lens, with Carl Zeiss optics, has a maximum aperture of F/1.8. This fast maximum aperture means that you can shoot handheld in low-light conditions while still getting outstanding sharpness and clarity.
The three aspherical elements, E-glass construction, and the special anti-reflective Carl Zeiss T coating provide images with sublime contrast and sharpness, no matter which setting you are using. It optimises performance and minimises distortion and flatness of the image, giving your images a deep, three-dimensional look. You can be sure that your shots will never be affected by any flaring or ghosting effects.
Because of the internal focusing mechanism, the lens tube does not move when focusing. In addition, the lens can boast its small dimensions, provides faster autofocus and a shorter minimum focus distance. The lens has a dust and moisture resistant design. It means that the lens will continue to perform reliably in moderately wet or dusty conditions, so you can shoot with confidence no matter where you are.
