Canon M42 T-Ring, EF-Mount Camera Adapter

This M42 T-Ring is designed to work with Canon EOS crop sensor cameras. A T-Ring couples your camera body to a T-Adapter, Radial Guider or Tele-Extender. This accessory is required if you want to do any type of photography through a telescope or spotting scope. For full frame Canon Cameras we suggest the M48 adapter.
