Bluestar specially designed the EVF-EC Eyecushion to fit our EVF35 and EVF50. Double thickness padding below an ultra-comfortable yellow Ultrasuede surface provides a luxurious amount of comfort. Eight special holes help conform the Eyecushion around the Camera Operator's eye to minimize the chance of light infiltration. Comes fully assembled and ready to go, simply stretch the neoprene backing around the eye-cup. Stays in place and won't fall off even in the most extreme environments.
