The Zacuto Anti-Fog Protective Covers (Pack of 3) provide a replaceable anti-fogging layer on your Z-Finder Pro and V2 viewfinders, at the same time protecting them from scratching and other damage. An anti-fog coating is especially important when moving your camera between warm and cold environments.

Note: If your Z-Finder Pro and V2 did not ship with the anti-fog protective covers then you will need the Anti-Fog Protective Cover Upgrade Kit in order for them to work, as the lens cap is slightly different than the one you have now.
