Viltrox has previewed new additions to its Evo lens series during The Photography & Video Show in Birmingham, indicating the development of two full-frame prime lenses based on apochromatic optical design. The lenses, expected to be a 35mm f/1.8 and a 55mm f/1.8, were shown in early form without full technical specifications or confirmed release timelines.

The announcement follows earlier references to these lenses during CP+ 2026 in Japan, where company representatives mentioned ongoing work on new Evo primes. The Evo line currently sits between Viltrox’s entry-level Air series and its higher-end Pro lenses, combining relatively compact construction with mid-range features such as metal housing and USB-C connectivity. The series was introduced with the AF 85mm f/2 Evo, which established the general positioning of the lineup in terms of pricing and performance.

The key characteristic of the upcoming lenses is the use of apochromatic correction: in optical design, this refers to the alignment of red, green, and blue wavelengths onto the same focal plane, reducing chromatic aberration and minimizing color fringing. The Chinese company has stated that it applies stricter internal criteria to the use of the APO designation, distinguishing its implementation from more loosely applied uses of the term in the broader lens market. Internally, the company refers to this approach as “Hyper APO.”

Although detailed optical formulas and performance data have not been disclosed, the adoption of apochromatic design suggests an emphasis on improved color accuracy and edge-to-edge clarity compared to standard designs. The lenses are expected to support autofocus and to be compatible with Sony E, Nikon Z, and L-mount systems, in line with recent Viltrox releases.

The presentation at the Birmingham event appears to serve as an initial public showing rather than a full product launch. Pricing has not been announced, but based on the existing Evo lineup, the lenses are likely to remain positioned below traditional high-end apochromatic optics. Further details are expected to be released soon.
