Pair the magnifying power and optical elements of a Hawke Optics spotting scope with your Sony NEX-E DSLR by using the Hawke Camera Adaptor - Sony NEX-E mount.
Its Sony NEX-E style bayonet mount clicks onto your camera in place of a lens.
You'll need a Hawke Digi-Scope Adapter, sold separately, to fit the eyepiece of your particular spotting scope.
