Even previously undetectable high-frequency details are now within the scope of our quality control inspections. However, we have developed our own proprietary MTF measuring system (A1) using 46-megapixel Foveon direct image sensors. We used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. This is the large-diameter wide-angle lens for which mirrorless camera users have been waiting. The lens for Micro Four Thirds offers a 32mm focal length (35mm equivalent) with the same bright F1.4 aperture. The 16mm F1.4 DC DN | Contemporary is the world's first interchangeable lens for mirrorless Sony E-mount cameras in the APS-C format to offer a 24mm focal length (35mm equivalent) and F1.4 brightness. Simply select a focal length that matches the image and enjoy complete control of the depth of field. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.Ī bright prime lens is the ideal way to experience the essence of the art of photography. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.įrom an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. The brass mount combines high precision with rugged construction. High-Precision, Rugged Brass Bayonet Mount The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions. The hood also features a rubber construction and a non-slip groove to make it easy to hold in a variety of shooting situations. The lens hood cuts harmful rays that can negatively affect photographs while also minimizing reflectivity within the hood itself. In summary, this is an unprecedented lens that combines outstanding optical performance with exceptional portability and usability. Structurally, the lens features materials and parts that contribute to its compact, lightweight structure. Moreover, this lens offers outstanding stability whether the photographer is shooting handheld or has the camera placed on a surface. The SIGMA 16mm F1.4 DC DN | Contemporary features SIGMA's inner focus technologies, while lighter lens elements in the focus lens group make possible a more compact actuator. Using face recognition AF results in consistent autofocusing on faces, even as the subjects move.Ĭombining Compactness With Outstanding Optical Performance The lens design fully accommodates the Fast Hybrid AF of Sony E-mount cameras for super-fast autofocus functionality. The optical design and stepping motor deliver smooth autofocus during video shooting. Stepping Motor For Excellent Autofocus & Quiet Performance The lens for Micro Four Thirds offers a 32mm focal length (35mm equivalent) with the same f-number of 1.4. The new SIGMA 16mm F1.4 DC DN | Contemporary is the world's first interchangeable lens in the APS-C format to offer a 24mm focal length (35mm equivalent) and F1.4 brightness. Offering An Opportunity To Experience The Fun Of Shooting Wide Open, With F1.4 Brightness
