The Zacuto Z-Finder Eyecup Replacement Kit includes the same eyecup originally shipped with your Z-Finder, along with a lens cap and 16:9 Sun Mask. It is fully compatible with all Z-finder Pro and Z-finder Jr models.
Rubber Eyecup Adds Comfort & Prevents Glare: The rubber Eyecup provides an extra degree of handling comfort as well as a crucial point of contact--between your camera and eye--that adds stability to any handheld video
16:9 Sun Mask: Because the Z-Finder can magnify any sunlight that enters it, it could cause harm to the LCD display. To prevent this, the included Sun Mask is housed within the eyecup, significantly decreasing the amount of light entering the lens & reducing any interior reflections within Z-Finder
Tethered Lens Cap: To completely block any magnified sunlight from entering the Z-Finder, the lens cap attached to the eyecup can be placed over the opening in the Z-Finder when not in use. It should always be used when you're not using the Z-Finder
