The lens barrel is of moderate weight, made of high-quality plastic. 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 lens features AF/M focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|M||Manual focus mode.|
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.
Due to the prominent convex profile of the front element the lens does not have a filter thread.
