Viltrox’s New EVO Series Lenses Have Leaked

The previously reported Viltrox AF 35mm f/1.8 EVO and AF 55mm f/1.8 EVO full-frame lenses for Nikon Z and Sony E have now leaked, giving us a clearer look at how both lenses are put together. The 35mm f/1.8 EVO uses a 10-element, 8-group design, paired with a 9-blade aperture and an f/1.8 to f/16 range. It can focus as close as 0.4 meters, uses a 55mm filter thread, and weighs somewhere between 340 and 370 grams. Autofocus is handled by an STM motor and there is no optical stabilisation.

The 55mm f/1.8 EVO is a bit more complex optically, with 11 elements in 8 groups, including ED and aspherical elements to help control aberrations and distortion. It keeps the same 9-blade diaphragm and f/1.8 to f/16 range, but focuses a bit farther out at around 0.5 to 0.55 meters. Filter size is again 55mm, and weight comes in between 340 and 380 grams. Autofocus also relies on an STM motor, with Viltrox saying it has been improved, especially when it comes to speed and subject tracking compared to earlier lenses.

Both lenses are built around what Viltrox describes as a true apochromatic (APO) optical design, meaning the lenses are designed to bring red, green, and blue wavelengths into focus at the same plane. This is intended to reduce axial chromatic aberration and colour fringing, particularly in high-contrast areas and out-of-focus transitions. Viltrox also makes it clear that it does not use the APO label lightly, pointing out that some lenses on the market carry the name without fully meeting that standard. Internally, the company refers to these designs as “Hyper APO,” suggesting it sees them as a step above typical implementations. Pricing and release date have not been announced yet.
