The Zeiss Batis 18mm F2.8 is from a family of Zeiss lenses named after a sub-Saharan flycatching bird. They’re all made specifically for Sony E-mount mirrorless cameras and a full-frame compatible, although naturally can also be used on Sony’s APS-C format E-mount bodies. The 18mm is the most wide-angle lens in the line-up, while siblings include the 24mm f/2, 40mm f/2 CF (Close Focus), 85mm f/1.8 and 135mm f/2.8. That covers most bases.
