Owner Notes: A lens with an angle of view so wide that it can capture very much of the life around us in a single frame – this is what the name Biogon© originally means. A focal length, produced with an almost symmetric lens design of surprising compactness, featuring the typical advantages of symmetrical lens designs: distortion is extremely well controlled, and so is color correction and image field flatness. DeClick feature One completely new feature of the Loxia lens is that you can ‘declick’ the aperture’s locking mechanism using a tool (supplied) and an adjustment screw on the bayonet surface. This means that for video applications, you can smoothly eliminate any unwanted differences in brightness as you pan the camera. This feature can also be used with other video systems whose size makes them suitable for adaption. Precise manual focus Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. ZEISS lenses stand out with their large rotation angle which enables precise focusing. Changes are immediately visible in the viewfinder. The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive interaction with the focal plane. The precise engraving in meter and feet, and the depth of focus scale provide additional support for manually focusing. Full frame compatible ZEISS lenses are suitable for digital Sony Alpha cameras and have been optimized for film and sensors up to full 35 mm format (24 x 36 mm).
