Designed in homage to the legendary Kern Macro-Switar lens for Alpa 35mm cameras, the black Canon RF-mount Thypoch Simera 35mm f/1.4 Lens has bright, low-light friendly optics in a sleek aluminum housing for high-quality imagery in a wide range of shooting scenarios. Its large aperture enhances depth of field effects including bokeh and subject-background separation. Featuring a declickable aperture ring and a grooved focus tab, the manual focus design is both tactile and wieldy. The optical design features three high-refractive index elements and an aspherical element for clarity from the center to the edge of the frame.
