This is the HoodEye for Select Canon EOS Cameras. This eyecup is a great way to prevent excessive ambient light from entering your viewfinder. By removing your camera's eyepiece and substituting the HoodEYE, you can improve your viewfinder clarity.
This item is camera specific - Please make sure you get the one that fits your camera.
Note! Will NOT fit the 5D and 5D Mark II.
On some camera models, HoodEYE eyepiece needs to be firmly put in place.
