This Z-Finder Will Fit the New Canon EOS 5D Mark III and Nikon D800
The Z-Finder Pro 3x for 3.2" screens is another one of Zacuto's Optical Viewfinders that allows small bodied DSLR cameras with 3.2" screens to have the correct form factor for video. It offers 3x focusable magnification (2.5x is available),a 40mm diameter Zacuto optical designed lens, an anti-fog coating protective cover, an eyecup preventing extraneous light leakage, a diopter and a field of view perfectly matched to 3" LCD screens. The diopter allows you to dial in the focus to match your eye. The 3x models are recommended for customers who are particularly farsighted or those who want the largest magnification possible. It will not crop any of the image. If you need extra focal point you can use the Z-Finder Extender Frames. The Z-Finder Pro 3x has a diopter range of -2.75 and up (unlimited with extender frames). These are semi-permanently stackable frames that attach to the skirt of the Z-Finder Pro and extend the Z-Finder glass further way from the LCD screen for people who are farsighted.The Z-Finder Pro uses the Zacuto Gorilla Baseplate and Z-Finder mounting frame to mount to the camera. (The Z-finder Mounting Frame can also be attached to their DSLR Baseplate )The Gorilla Baseplate attaches to the bottom of your camera using a 1/4-20” screw and the Z-Finder mounting frame attaches to the Gorilla Baseplate using thumb screws. The rubber back mounting frame does not attach to your LCD; it is held in place against your LCD with pressure. This method allows you to quickly remove the Z-Finder Pro by snapping it off the frame. If you want to remove the entire mounting frame from your camera, you can do so by loosening the thumb screws and pulling up on the metal mounting frame to release it.
