This is a tilt-shift mount adapter that converts M42 mount old lenses to Sony E mount. It allows you to use regular M42 mount lenses as if they were tilt-shift lenses. I purchased this on Amazon in December 2018 to play with old lenses, but I haven't used it since and have been storing it, so I am selling it. Please check the photos for the condition of the product and included accessories. * There is no packaging, only the items shown in the photos will be included.
