A Nano AR coating has also been applied to individual lens elements to minimize lens flare and ghosting for increased contrast and color fidelity when working in strong lighting conditions

this prime lens incorporates a series of aspherical and extra-low dispersion elements

the lens manages to remain relatively lightweight and compact

Three extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color accuracy
