Sony Zeiss Vario-Sonnar T* 24-70mm f/2.8 ZA SSM

	Ultrasonic AF Lenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. No stepping motor AF Lenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses. One or more Low Dispersion lens element is used Low Dispersion lens elements help to reduce chromatic aberration. Not stabilized Image stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Metal mount Cheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important. Internal Focusing Internally focusing lenses don't change their size while setting focus. No Internal Zoom Internally zooming lenses don't change their size while focal length is changing. The front lens is fixed The fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. No drop-in filter support Drop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type.
This lens (equivalent to 36-105mm in 35 mm format) aims at a performance level equivalent to fixed focal length lenses or higher. High speed silent AF operation thanks to the SSM(Super Sonic wave Motor). 2 aspherical elements and 2 ED glass elements.
