This T-Ring is designed to work with Sony and Konica Minolta SLR cameras.

The T-Ring couples your camera body to either a T-Adapter, Radial Guider, or Tele-Extender. This accessory is necessary for photography with a SLR camera, through a telescope or spotting scope. Simply remove your lens and attach the T-Ring in its place. Then, attach the camera to whatever adapter you are using to connect it to a telescope or spotting scope.
