A Compact Everyday Lens with a Vintage RenderingNamed after the Sanskrit Ksana, the Ksana Series represents the eastern concept of the "instant". At roughly 0.018 seconds-nearly a 1/60s shutter speed-a ksana is the duration of a sudden enlightenment. If photography captures this singular "now", can these frozen moments inspire the future? Perhaps photography is simply the art of the eternal instant.The Ksana series is ultra-light and compact, making these lenses the perfect "everyday carry" and capturing precise, fleeting moments. Furthermore, each lens is equipped with a unique vintage coating, offering distinct characteristics that provide photographers with a continuous flow of inspiration.Capture a Fleeting InspirationAs the first lens of the Ksana series, the 21mm f/3.5 blends classic aesthetics with vintage rendering. Its compact all-aluminum body is built for effortless daily carry and perfectly complements the Leica aesthetic. Featuring Epoch Coating.73', it recreates the iconic 1970s golden-amber flare, infusing every frame with a poetic atmosphere and boundless creative inspiration.Epoch Coating.73': The Retro LookEpoch Coating is a specialized project exploring the aesthetic soul of different eras. As time settles upon the glass of various decades, the resulting flare becomes as unique as a fingerprint-a distinct personality for every lens. Drawing from our deep heritage in cinema optics, we have successfully translated the magnificent flare of cinema lenses into the world of still photography.In the 1970s, Japanese lens craftsmanship employed unique coating processes that imbued images with amber-toned, multi-layered flares and a soft, delicate rendering. This specific visual temperament defined the breathtaking aesthetics of films like "Her", gradually becoming a vintage nostalgia in modern cinema. Epoch Coating.73' utilizes modern technology to recreate that iconic 1970s texture, reviving the warm amber flares and distinctive tones of classic cinema glass.
