|AS(PHERICAL)||The lens incorporates aspherical elements to minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.|
|UMC||The multi-layer coating is applied to the surface of lens elements. It boosts light transmission, ensures sharp and high contrast images, minimizes ghosting and flares.|

Design and Features
The lens barrel is of moderate weight, made of metal. The lens mount is metallic.
Focusing must be performed manually using the focusing ring located on the lens barrel.
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).
The lens has no CPU and does not transmit EXIF data to the camera.
