About: Thypoch Simera 21mm F1.4 Full-Frame Photography Lens (M Mount) - Silver
The Simera 21mm f/1.4 ASPH is a breakthrough in ultra-wide-angle, large-aperture lens design. Ten years after the first 21mm f/1.4 lens was created, Simera 21mm redefines what this focal length can achieve. With 13 elements in 11 groups, including advanced special elements and high-precision aspherical lenses, it achieves an impressive minimum focus distance of 0.23m.

The floating lens design ensures smooth background separation and soft, beautiful bokeh even at wide-open aperture. The lens delivers almost imperceptible distortion, minimal chromatic aberration, and sharpness from the center to the edges of the frame. It adds a rich, cinematic texture to low-light scenes and blends wide perspectives with fine details, making it a perfect tool for creative expression.
The 21mm focal length is a favorite in cinematic storytelling, known for its ability to show expansive spaces or dramatic details. From the days of Super 35 film to today’s full-frame cameras, this focal length has been loved for its calm yet slightly surreal look. Drawing on years of experience creating fast 21mm cinema lenses, we’ve brought the precision and depth of cinema optics into a lens made for everyday artistic use. Weighing just 428g, this lightweight full-frame lens combines ultra-wide perspective with ultimate close-up capabilities, giving you the freedom to shoot everything from sweeping landscapes to intricate details with ease.
Optical Precision, Pure and Vivid Imagery
The Simera 21mm f/1.4 features 2 ASPH. elements, 3 HRI, and 3 ED elements, combined with a floating lens group to achieve minimum chromatic aberration and distortion even at a wide-open aperture. Its advanced optical design delivers exceptional sharpness across the entire frame from center to edge, and maintains exceptional clarity and depth even on 60MP sensors.
With its f/1.4 aperture, the lens excels in low light and creates smooth transitions between highlights and shadows. Precision-crafted aspherical elements eliminate distracting “onion ring” and “donut” bokeh, ensuring a clean image. The 14-blade cinema-grade aperture produces beautifully rounded, dreamy bokeh that adds an artistic and unique touch to the images.

Immersive Perspective, Expansive and Expressive
The 21mm has long been favored by filmmakers for its calm yet slightly surreal atmosphere. Its wide-angle perspective not only adds strong spatial depth to the frame but also creates a “cognitive distancing effect” when capturing close-up portraits. This allows both the environment and fine details to be expressed naturally.
The f/1.4 aperture offers a shallow depth of field that mimics the natural separation of the human eye at medium distances. At its minimum focusing distance of 0.23m, it achieves bokeh effects comparable to those of a 50mm f/1.4 lens at 0.55m. The near-90°diagonal field of view further enhances the sense of space in landscape photography and delivers strong visual impact. Whether capturing environmental portraits, close-up details, or sweeping vistas, this lens offers an immersive visual experience, adding narrative depth to every frame.
Lightweight and Versatile, Freedom in Creation.
Weighing only 428g, the Simera 21mm f/1.4 is the lightest in its category, offering an exceptional balance between performance and portability.
Designed for landscape, documentary, and street photography, it ensures effortless handling across various creative scenarios. The lens features a de-clickable aperture ring for seamless transitions between still and video shooting.
A tactile resistance point at 0.7m serves as a reminder for rangefinder focus limits.
The specially designed ultra-wide lens hood allows quick mounting and folding, offering a smooth and comfortable handling experience.
