The Z-Finder Eyecup Replacement Kit from Zacuto 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. With your eye held up against the Eyecup, your Z-Finder system will prevent light from spilling onto your LCD, and removes any distracting glare or shadows.
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, and reducing any interior reflections within the Z-Finder. This does not protect 100% of the LCD, so users must still use the lens cap when working outside every time the Z-Finder is not in use.
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.
