The Thypoch Simera 21mm f/1.4 ASPH. is a fast ultra-wide prime lens for Leica M-mount cameras, combining an expansive 21mm field of view with a bright f/1.4 maximum aperture for immersive wide-angle photography. With a minimum focusing distance of 0.23m, it captures everything from sweeping landscapes and architecture to dramatic close-up compositions with strong depth and perspective.
Its advanced optical design features 2 aspherical elements, 3 ED elements, and 3 high-refractive-index elements in 13 elements / 11 groups, delivering high sharpness from center to edge, strong distortion control, and excellent correction of chromatic aberration. A 14-blade diaphragm helps produce smooth out-of-focus rendering and appealing sunstars, while the floating optical design maintains strong performance from close focus to infinity.
Designed for photographers who want both classic rangefinder handling and modern imaging performance, the lens also features Visifocus depth-of-field visualization, a durable all-metal body, and a tactile focusing feel that supports intuitive transition between rangefinder and EVF-assisted focusing.
Thypoch is a cinema-lens brand launched in Shenzhen in 2023.
