Short-Tele/Macro E-Mount Lens. With a 35mm-equivalent focal length of 75mm, the Touit 50mm is designed to be used as a macro lens. It reaches a true 1:1 reproduction ratio with a 6.0-inch minimum focusing distance. The Touit 50mm’s 75mm-equivalent focal length means that it’s also a great portrait lens—its f/2.8 aperture enables good subject/background separation. It features full electronic compatibility with Sony E-mount camera features, including autofocus, exposure control, and EXIF data.

Optical Design. The Touit 50mm is based on the classic Planar formula, which is designed to correct for most aberrations and distortion across a wide range of reproduction ratios. 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.
