Sony 50mm f/1.4 Standard Lens

see the whole gallery in large	Full frame sized image Lenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. No 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. No 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. No Internal Focusing Internally focusing lenses don't change their size while setting focus. 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. Not Sealed Weather sealed lenses are protected from dust and water. While they are not water proof, these lenses can be used in rain and other humid environments. Some sealings only provide protection against dust or water, not both. Sealing is only available when the lens is used on a similarly weather sealed camera body. 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.
An ultra-bright standard lens for fast, accurate shooting by available light. For quick candid shots that capture ""the decisive moment,"" this lens provides superb clarity and visual accuracy even with fully open aperture when working indoors or in low-light and twilight conditions. Mounted on the Sony® α (alpha) DSLR-A100 camera, this lens provides midrange telephoto 75mm focal length (35mm equivalent) -- and takes advantage of the in-camera Super SteadyShot® image stabilization system to minimize blur from shaky hands.
