Thypoch Simera-C 21mm T1.5 Full-Frame Cine Prime Lens (Leica M-Mount)

The Thypoch Simera-C 21mm T1.5 (M-Mount) is a dramatic wide-angle cinema prime designed for Leica M-mount cameras – and adaptable to Canon RF, Nikon Z, Leica L, Fujifilm X and Sony E-mount via readily available adapters. At 21mm, it's the widest lens in the Simera-C range, purpose-built for sweeping establishing shots, immersive environments, and any scene demanding dramatic perspective and depth.

At 472g with an aerospace-grade aluminium body, it's lightweight enough for gimbal and drone work without sacrificing the optical quality expected of a professional cine prime.
