- Prime wide-angle lens provides a 35mm-equivalent focal length of 16mm, making it ideally suited for indoor, architectural, and landscape subjects.
- Fast f/2.8 maximum aperture benefits working in low-light conditions.
- Manual focus design permits selective control over focus placement.
- One extra-low dispersion element and two aspherical elements reduce chromatic aberrations and distortions in order to produce sharper images.
- Nano crystal anti-reflection coating system improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.
