The Zeiss Touit 12mm f/2.8 Lens (Fujifilm X-Mount) is a
wide-angle prime lens designed specifically for use on APS-C-sized image
sensors, and as such provides a 35mm-equivalent focal length of 18mm.
This lens is compatible with Fujifilm X mirrorless cameras and supports
all camera functions, including autofocus and exposure control.
The Distagon design of this lens integrates a floating element design
that includes two aspherical elements and three partial-dispersion
elements to reduce aberrations and distortion to produce high image
clarity, sharpness, and even brightness. Carl Zeiss T* anti-reflective
coatings have also been applied to all lens surfaces to improve light
transmission and image contrast by minimizing surface reflections, lens
flare, and ghosting.
The construction of the lens features a
metal lens barrel with rubberized control rings for high precision when
manually focusing. A rigid metal bayonet mount ensures accurate
alignment and a nearly circular nine-blade aperture works to produce an
aesthetic out-of-focus highlight quality.
