The optical scheme hasn't changed - seven elements in five groups, including two aspherical elements. The lens is equipped with an AF micro-motor. The filter does not rotate while focusing. The lens features a metal lens body and bayonet mount. It is available in silver or black colors. The lens hood is not included.
