I am using a D5200 and want to make an attachment to support the lens at a distance away from the camera body. (There will be no lens mounted to the camera. Then there will be a gap. Then the lens.)
Because the lens support will be off-camera, and all components have to be aligned along the optical axis, the vertical height of the center of the center from the base of the camera is important. I am not able to find any reference/documentation online pertaining to this.
Any help, suggestions, or references for building this support, or finding the vertical height of the center of the sensor from the base of the body, would be appreciated.
