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 2.8/21 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 2.8/21 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 2.8/21 is extremely compact and light, making it the perfect choice for travel and street photography.

ZEISS Loxia 2.8/21 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 2/35 and ZEISS Loxia 2/50, 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 2.8/21 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.
