This compact and lightweight Vario-Tessar E-mount zoom lens with 16 - 35 mm focal length from Zeiss offers outstanding performance for full-frame cameras. A versatile zoom range, coupled with built-in optical image stabilisation, makes it the ideal choice for snapshots, indoor shots, group shots, landscape shots and more, especially when connected to a full-frame α7 series housing. A constant maximum F4 aperture makes exposure easier and provides more depth of field. This compact wide-angle zoom lens covers a convenient focal length range and offers excellent image quality, especially in combination with a full-frame sensor such as the one used in the α7 camera series. The legendary Zeiss quality packaged in this fast 50mm lens also ensures first-class resolution and contrast thanks to the T* coating. MTF (Modulation Transfer Function) is a function that indicates how well a lens can reproduce fine details - measured as contrast ratio.
