The Zacuto C300/500 Z-Finder is an optical viewfinder developed for Canon Cinema EOS Cameras — specifically: the C300, C300 AF, C300 Mark II, and the C500. It is not compatible with other cameras or setups. It magnifies the LCD screen by 1.8x, cuts out excess light, and provides a comfortable eyecup with diopter.
Four Diopters. The Z-Find-C3 includes four interchangeable anti-fog glass diopters: 0, +1, +2, and +3. Two other diopters, -1 and +4, are available for purchase separately.
Professional Grade Construction. The Zacuto Z-Finder for the C300 and C500 is built with an aluminum sun mask to protect the LCD from sunlight. This viewfinder attaches to the camera by using a foam padded sleeve that slides over the LCD screen; the sleeve is secured into place with a bar clamp. When the Z-Finder is pressed against a user’s eye, a unique monitor lock clip keeps the LCD from moving forwards. The red locking handle is easy to use; easy on, easy off.
Note: The Z-Finder is a magnifier and as such will magnify the sun which can damage the LCD screen if the sun is allowed to shine directly through the Z-finder lens. Use the included lens cap to block light from entering your Z-finder when not in use.
