Zeiss Loxia 21mm f/2.8 (Sony E-mount)

ZEISS Loxia 21mm F2,8 It is a super wide angle, developed for compact full-frame cameras with E-mount and with a new optical design based on the ZEISS Distagon.   With an angular field exceeding 91 degrees (diagonal) on a full-frame camera, the ZEISS Loxia 2.821 is well suited for nature, landscape and architectural photography. In landscape photography in particular, an exact infinity setting is a critical factor. Here, the precise manual focusing of the ZEISS Loxia 2.821 supports the user enormously. Furthermore, the lens enables creative, naturally proportioned images with a low minimum object distance of just 0.25 meters. The ZEISS Loxia 2.821 is extremely compact and light, making it the perfect choice for travel and street photography.   ZEISS Loxia 2.821 is a tool that offers optimum creative potential. The mechanical deactivation of the aperture click stop for infinite aperture settings (de-click), which already came with the ZEISS Loxia 235 and ZEISS Loxia 250, is also found in the new ZEISS Loxia super wide angle. The smooth focus operation with a rotation angle of 90 degrees of the ZEISS Loxia 2.821 allows for the finest variations when focusing video cameras with E-mount, such as the Sony PXW-FS7 or PXW-FS5. In addition, the identical external diameter of the ZEISS Loxia lenses across all focal lengths simplifies the changing of lenses during shoots, so accessories like a follow focus don't need to be readjusted.   High precision   Precise and durable construction, low weight. The functionality of the Loxia lenses is perfectly matched with the camera functions of the Sony a7-series.
