Thypoch Simera 21mm f/1.4 FullFrame - Leica M-Mount - Black

Thypoch Simera 21mm f/1.4 Full Frame Lens for Leica M-Mount - Black

This compact 21mm full-frame prime brings an expansive wide-angle view together with refined optical performance. Designed for Leica M-mount cameras, it delivers the kind of image character that feels both cinematic and precise, making it a compelling choice for photographers who want strong technical performance without sacrificing atmosphere.

With a bright f/1.4 maximum aperture and a 14-blade diaphragm, this lens produces smooth, rounded bokeh and beautiful starbursts when stopped down. Precision-molded and polished aspherical elements help keep distracting bokeh effects at bay, while the carefully balanced optical design supports clean transitions between in-focus and out-of-focus areas.

The optical construction includes 13 elements in 11 groups, featuring 2 aspherical elements, 3 high-refractive-index elements, 3 low-dispersion elements, and a floating group. Together, these components help maintain excellent sharpness, low chromatic aberration, and strong control over distortion across the frame, even when shooting wide open.

Weighing just 428 grams, the Simera 21mm f/1.4 offers an impressive blend of portability and performance. Its short minimum focusing distance makes it versatile for everything from sweeping landscapes to intimate street scenes and environmental portraits, giving images a sense of depth that feels natural and immersive.
