The lens utilizes an optical structure of eight elements in six groups, incorporating two aspherical lenses and one high-refractive element to maintain image clarity and minimize distortion. Despite its slim profile, the 26mm prime features a gear-type stepping motor system that provides fast, responsive autofocus, even when tracking moving subjects. It also allows for close-up work with a minimum focusing distance of 7.9 inches.

Beyond its optical performance, the construction emphasizes durability and tactile control. Viltrox has integrated a metal chassis with dust and water-resistant coatings, distinguishing the lens from many competitors in its weight class. A unique inclusion of separate aperture and focus rings offers photographers a more manual shooting experience, while a USB-C port allows for straightforward firmware updates. The package is rounded out by a magnetic lens cap system, now available for purchase through retailers like B&H.
