We specially designed this Eyecushion to fit the beautifully made ikan 3.5" 4K LCD Viewfinder. Double thickness padding below an ultra-comfortable yellow Ultrasuede surface provide a luxurious amount of comfort. 8 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. This special Eyecushion is available directly from ikan.
