The HoodEYE Nikon 22mm Square from Hoodman is an effective eyepiece that blocks the light from disrupting your camera system's viewfinder. The oversized design, ambient light protection, and full-rotation to allow for left/right-eyed shooting - all combine to ensure that Nikon 22mm square eyepiece shooters can capture images with ease. To attach, utilise the self-locking mount and slide it swiftly over the eyepiece mounting rails. This allows for a secure, efficient, and enhanced still-image setup which is especially effective in bright conditions. To confirm a comfortable shooting experience for all users, Hoodman have used a hypoallergenic silicone to reduce irritation and allow for extended usage. This is compatible with the Nikon D750, D610, D600, D300, D300s, D200, D100, D90, D80, D70, F70s, D60, D50, D40, D40x, D3000, D3100, D3200, D3300, D3400, D7000, D7100, D7200, D5000, D5100, D5200, D5300, D5500, D5600.
