Optical Precision, Pure and Vivid Imagery

Featuring 2 ASPH., 3 high-index, and 3 ED elements, along with a floating element design to minimize chromatic aberration and distortion even at f/1.4. The lens delivers edge-to-edge sharpness and resolves fine detail even on 60MP sensors.

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.

The f/1.4 aperture offers a shallow depth of field that mimics the natural separation of the human eye at medium distances. At its minimum focusing distance of 0.23m, it achieves bokeh effects comparable to those of a 50mm f/1.4 lens at 0.55m. The near-90°diagonal field of view further enhances the sense of space in landscape photography and delivers strong visual impact. Whether capturing environmental portraits, close-up details, or sweeping vistas, this lens offers an immersive visual experience, adding narrative depth to every frame.

Weighing only 428g, the Simera 21mm f/1.4 is the lightest in its category, offering an exceptional balance between performance and portability.

The specially designed ultra-wide lens hood allows quick mounting and folding, offering a smooth and comfortable handling experience.
