A:Answer Yes. The camera has a pullout, single-eye viewer, and the power remains on with the eyepiece viewer open and the monitor screen-door closed. However, if you wear darkened glasses that obscure your ability to see the viewer screen, there won’t be any advantage to looking through the eye-piece. If you don’t need corrective sunglasses to see, then the eye-piece viewer should be a definite advantage in bright sunlight, at least that’s my myopic experience.
