The black Lens2scope Adapter for Canon EF / EF-S Mount from Kenko is an accessory that can change any lens into a spotting scope. The adapter's lightweight composite body houses a good quality roof prism, optics, and an eyepiece just like a traditional spotting scope. When the lens is attached, it becomes a spotting scope to use for viewing. The lens mount and housing for the optics are made from metal while some external barrels made of polycarbonate.
