Wide-Angle E-Mount Lens. With a 35mm-equivalent focal length of 18mm, the Touit 12mm is a great option for landscape and architectural photography. It features full electronic compatibility with Sony E-mount camera features, including autofocus, exposure control, and EXIF data.

Optical Design. Based on the classic Distagon design, the Touit 12mm features a floating-element construction that uses two aspherical elements and three partial-dispersion elements. This provides images with low chromatic aberrations and distortion while offering increased sharpness and even illumination. Each element has Carl Zeiss T* anti-reflective coatings to help minimize reflections and boost image clarity and microcontrast. A nine-blade, nearly circular aperture renders out-of-focus highlights.

Durable Build. The Touit line of lenses is constructed with durable metal barrels that feature rubberized control rings for improved manual-focus performance over most available E-mount lenses. Its all-metal bayonet mount ensures a solid camera/lens connection.
