About the product

Optical precision, pure and vivid imagery

The Simera 21mm f/1.4 uses 2 aspherical, 3 high-refractive, and 3 extra-low dispersion elements, combined with a floating lens group to reduce chromatic aberration and distortion. This design ensures sharpness and clarity across the frame, even on high-resolution 60MP sensors.

Fast aperture

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 focal length is popular with filmmakers for its calm yet slightly surreal look. It enhances spatial depth and, in close-up portraits, creates a sense of distance while still showing both the environment and fine details naturally.

Creative possibilities

With its f/1.4 aperture, the lens creates a shallow depth of field similar to natural human vision. At 0.23 m minimum focus, it produces bokeh effects comparable to a 50mm f/1.4 at 0.55 m.

Its near-90° field of view adds depth to landscapes and strong impact to every shot. From portraits to close-ups or wide vistas, it delivers an immersive look that enhances storytelling.
