USED Sigma 16-28mm F2.8 DG DN Contemporary for Sony E

Product Features

• A "high-performance compact zoom" that condenses uncompromising optical performance into a lightweight and compact lens body. Optimized lens configuration through the latest optical design, taking into account the short flange back and in-camera optical correction functions, achieves both high optical performance and miniaturization.
• Two large-diameter aspherical lenses at the front contribute to the overall compactness and high optical performance of the lens. Five pieces of FLD glass, which have the same characteristics as fluorite, are optimally arranged to effectively suppress the magnification chromatic aberration and axial chromatic aberration that are particularly problematic in ultra-wide-angle lenses.
• Enjoy uniform and sharp depiction from the center to the periphery of the screen, and beautiful bokeh. In close-up photography, you can create a three-dimensional image by utilizing the background blur unique to F2.8. Since ghosts and flares are prone to occur when the sun enters the frame in ultra-wide-angle zooms, thorough countermeasures have been taken from the design stage. The Super Multi-Layer Coating provides excellent anti-reflective performance.
• A 72mm front filter can be attached. PL filters and ND filters, which are often used in ultra-wide-angle photography, become easier to use.
• A stepping motor is used for the AF actuator. The agile and quiet AF is ideal not only for still images but also for video shooting.
• Polycarbonate "TSC (Thermally Stable Composite)", which has a thermal shrinkage rate close to that of aluminum, is used in appropriate places. This reduces errors due to thermal shrinkage between metal parts and ensures stable performance even in environments with large temperature fluctuations.
• The pursuit of external beauty is also due to the high manufacturing technology and strict quality control of the SIGMA Aizu factory. It is not just a convenient and compact zoom lens, but also meets expectations in terms of operability and quality as a shooting instrument.
