It features a metal, knurled, petal-type lens hood, and a 62mm threaded front filter. All I series lenses feature a distinctive arc-type AF/MF switch and stylized barrel design.

With an F2 aperture, this lens is a good choice for astrophotography, along with landscapes, cityscapes, street photography, low-light interiors, and other nighttime situations.

The optical construction of the lens includes three high-precision glass-molded aspherical lens elements, one SLD element, and one FLD element to suppress a range of optical aberrations. There is also Super Multi-Layer Coating and Nano Porous Coating (NPC), which is claimed to ensure very minimal flare and ghosting even when shooting into bright light sources
