Design and Features
A pre-production version of the lens shown at PMA 2010 had “crinkle” paint finish that was a hallmark of Sigma’s design for many years. Production version, however, received classic smooth matte paint finish.
The lens barrel is heavy, made of metal. The lens mount is metallic.
The lens features AF/M focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|M||Manual focus mode.|
The lens uses front filters with standard size of 77 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
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 equipped with ultrasonic motor, the autofocus is virtually silent and fast. Some people also find the autofocus of this lens to be inconsistent/inaccurate, but this is usually the result of one’s inability or inexperience in shooting at large apertures where this lens provides very narrow depth of field. Focus shift, which is typical for large aperture prime lenses, does not facilitate the task of autofocus system either. In such situation the autofocus errors are unavoidable even with professional DSLR cameras, especially in low-light conditions.
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 sharpness is very good at the center of the frame already wide open and excellent from F/2. The edges are good wide open and very good from F/2. The background blur is smooth and pleasant at large apertures. The lens suffers from focus shift when stopped down though.
