The HoodEYE Canon 22mm 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 Canon 22mm 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 Canon 1D Mark III, 1Ds, Mark III, 7D, 7D Mark II, 1D Mark IV, 1D-X, 1D C, 1D-X Mark II, 5D Mark III, 5D Mark IV, 5DS, 5DS R.
