Touit 12mm f/2.8 for Sony E-mount
Wide-angle prime lens
The Zeiss Touit 12mm f/2.8 Lens for Sony E-Mount is a wide-angle prime lens designed specifically for use on APS-C-sized image sensors, where it provides a 35mm-equivalent focal length of 18mm. When used with Sony E mirrorless cameras it will support 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 for consistent clarity, sharpness, and illumination. 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 produces pleasing bokeh.
