The Clavius Prime lenses from Richard Gale Optics present an unmatched fusion of vintage charm and modern versatility. Beyond their nostalgic aesthetic, the Clavius Prime lenses also present a wealth of artistic options. These lenses are equipped with interchangeable aperture inserts, facilitating anamorphic bokeh while maintaining the convenience of shooting spherical.
At their heart, these lenses incorporate a 1970s Russian Helios 58mm optical block, supplemented by conversion optics to achieve 28mm, 38mm, and 88mm focal lengths while preserving the original vintage qualities.
The end product is a vintage, low-contrast appearance that adeptly softens sharp contemporary sensors while covering Full Frame/Vista Vision sensors.
