The exceptionally bright medium telephoto Sonnar T* 1,8/135 ZA lens by Carl Zeiss captures detailed portraits and close-ups, with superb resolution and a shallow depth of field, enabling you to visually isolate a scene through the use of beautiful background blur. Fast autofocus and a 135 mm focal length make it ideal for capturing fast-moving sports and wildlife. The elaborate mechanical design of the interior focusing of the optics also enables outstanding image quality for exposures on very close objects. Its aperture of 1.8 gives you the flexibility to get up close to your subject, even in difficult lighting situations.
