The H-D50 FlipUp® cap clips into place by slipping the original Nikon D50 eye piece up and off the camera. Next slide the H-D50 FlipUp® cap over the eyepiece mounting flanges to cover the entire LCD screen. The cap provides protection for the delicate LCD screen when in closed position. The cap flips up into a three sided hood for improved outdoor viewing. Priced at $34.99, the H-D50 FlipUp® is a great investment in LCD screen protection and performance. For Nikon D50 models only.
