The optical scheme consists of 12 elements in 10 groups, including 1 aspherical lens to reduce chromatic aberration and 2 high-refractive lenses to reduce dimensions and weight.  A high-quality multilayer and anti-reflective coating is applied to increase contrast and improve color rendering. The lens has floating elements to maintain  high quality of the image at the closest focusing distance.
