Simera 21mm F/1.4 M Mount Black Lens

The Simera 21mm f/1.4 ASPH is an ultra-wide, large-aperture lens that pushes the limits of this focal length. With 13 elements in 11 groups, including advanced aspherical glass, it achieves sharpness from center to edge, minimal distortion, and excellent control of chromatic aberration. Its floating design ensures smooth background separation, soft bokeh, and a close focusing distance of just 0.23 m. Lightweight at 428 g, it combines wide perspectives with close-up precision, adding cinematic texture in low light. Long favored in filmmaking for its ability to capture both expansive spaces and dramatic details, the 21mm focal length here brings cinema-grade quality into a compact lens for creative, everyday use.
