|E||The lens is designed only for Sony APS-C digital mirrorless cameras.|
|OSS||The lens is equipped with optical image stabilizer. The stabilizer allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without stabilizer you will have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.|

The lens barrel is of moderate weight, made of metal. The lens mount is metallic.
The lens has rather narrow focal range. Formally it is the disadvantage, however in practice it contributes to a good compensation of optical aberrations and equally high image quality at the entire focal range.
The focusing ring is not physically coupled with the focusing mechanism and works electronically (focus-by-wire) - turning of the ring actuates an electric motor that moves the focusing group of the lens to the proper position to achieve sharp focus.
The lens lacks focusing mode switch, therefore you have to set the automatic or manual focus mode from the camera.
The lens uses front filters with standard size of 62 mm which are easy to find. They are also inexpensive.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
Aspherical elements (ASPH, XA) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
The lens features optical image stabilizer.
