The Zeiss Touit 50mm f/2.8M Lens (Sony E-Mount) is a moderate telephoto macro lens designed for use on cameras with APS-C format sensors and as such provides a 35mm-equivalent focal length of 75mm. This lens is compatible with Sony E mirrorless cameras and supports all camera functions, including autofocus and exposure control. With a 1:1 magnification ratio, it offers close-up macro capability and its minimum focus distance is 6". An f/2.8 maximum aperture is effective in low light and provides shallow depth of field focus.
A complex floating lens system ensures a uniform length when focusing and provides consistently sharp performance. The optical design includes two aspherical elements and two anomalous partial dispersion elements which minimize lateral and longitudinal chromatic aberrations.
