DZO Thypoch Full-frame Photography Lens Simera 21mm f1.4 for Leica M Mount_Black

The Simera 21mm f/1.4 brings a wide-angle perspective to the Simera range, combining a wide field of view with precision optical design. The lens is designed for full-frame cameras with M mount. Color: Black.

Originally launched as part of the Simera-C film series, this lens now comes in a photographic version with an M bayonet that retains the same film standards. It features a 14lamel aperture that maintains a perfectly circular aperture shape throughout the entire range from f/1.4 to f/16. Precision-molded and polished aspherical elements effectively eliminate unwanted bokeh artifacts such as "onion ring" or "donut" effects and provide clean, natural light transitions.

The Simera 21mm f/1.4 lens is constructed with 13 optical elements in 11 groups, including 2 aspherical elements, 3 high refractive index elements and 3 low light scattering elements, and also includes a floating lens group. This assembly ensures minimal chromatic aberration and near-zero distortion even at maximum aperture, while providing exceptional resolution across the entire image area - from the center to the edges.

At just 427g, it is the lightest full-frame 21mm f/1.4 lens in its class, striking a rare balance between performance and portability. Ideal for landscape, documentary and street photography, it offers a cinematic visual experience and exceptional narrative depth that few lenses in this category offer.

With an exceptionally short minimum focusing distance and outstanding optical performance at full aperture, the Simera 21mm f/1.4 ASPH is a versatile and inspiring tool for capturing everyday moments.

At f/1.4, the lens renders a subtle and natural transition between sharp and out-of-focus areas, both in the foreground and background, very close to the way the human eye perceives depth. This characteristic brings an immersive, cinematic quality to images that is rather rare in ultra-wide-angle lenses.
