Design and Features
The lens barrel is compact, of moderate weight, made of high-quality plastic. The lens mount is metallic.
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 49 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 is based on almost symmetric variant of double Gauss design which is one of the most developed lens designs in the world frequently used for large aperture standard prime lenses and large aperture moderate wide-angle prime lenses. It provides excellent compensation of aberrations, except for the oblique spherical aberration which lowers peripheral contrast.
Aspherical elements (ASPH, XA, XGM) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
