Zeiss 40mm f/2 Batis CF Lens: Sony FE
Standard prime lens
Offering a unique short-normal focal length with a close-focusing design, the Batis 40mm f/2 CF from ZEISSis a Sony E-mount prime further characterised by its advanced optical layout. The innovative design of Batis lenses feature an OLED display that highlights the focus distance and depth of field range for quickly recognising your focusing parameters, and autofocus is handled by a linear motor that maintains quick, quiet, and smooth performance.
In regard to optics, the lens employs a Distagon concept with a floating elements design, which maintains consistent sharpness and illumination throughout the focusing range, and a series of aspherical and low dispersion glass elements help to control both chromatic and spherical aberrations. A ZEISS T* anti-reflective coating has also been applied to individual elements in order to suppress flare and ghosting for improved contrast and colour fidelity, and the lens also sports a dust- and moisture-sealed construction to permit its use in trying environments.
