The Simera series offers more options for different mounting systems and makes it versatile for Sony, Nikon, Fujifilm and Canon cameras. 1. exquisite ergonomics, fluid precision The Simera lenses feature a crescent-shaped focus rod made of anodised aluminium alloy for seamless integration and tactile comfort. The ergonomic curve enables fast focussing with smooth precision and elevates the photography experience to a special level. 2. classic depth of field indicator In homage to the Alpa Kern lenses, Simera incorporates a vintage-inspired depth-of-field indicator that adds a touch of nostalgia to the design. Versatile and fascinating, it facilitates zone focussing. 3. versatile control, intuitive adjustments Simply tap the sun and moon icons on the aperture ring to switch between click and de-click modes. This offers artistic freedom and fine control in a variety of shooting scenarios. 4. large aperture f1.4 The large aperture improves low-light performance and makes it easier to capture well-exposed images in difficult lighting conditions, such as indoors or when shooting at night. A shallower depth of field creates a blurred background and achieves better separation between subject and background. 5. state-of-the-art optics for exceptional detail Controlled chromatic aberration and distortion for the Simera series. With one ED, two HRI and one aspherical lens in 28 mm and three HRI and one aspherical lens in 35 mm, image quality remains clear even at close focus and wide open aperture, with a smooth transition from centre to edge.
