Zacuto Z-finder V2 Optical viewfinder for DSLR's has been discontinued, here are some related products you might like:
The Z-Finder is Zacuto’s Optical Viewfinder that allows DSLR cameras to have the correct form factor for video. It offers 3x focusable magnification, a 40mm diameter lens, an eyecup preventing extraneous light leakage, and a field of view perfectly matched to LCD screens.
With Optics by Schneider, this 6 oz viewfinder is a filmmaker’s best tool for creating precision focus.The Z-finder currently fits the Canon 5d, Canon 7d, Nikon D90, Panasonic GH1 and many other cameras.
The Z-finder is made to fit a 3” diagonal screen but other factors come into play such as button placement, slanting of the camera viewfinder etc.
Please see below for interior dimensions of the Z-Finder.
The Z-Finder attaches to your camera LCD by using a flat snap fit frame.
The snap fit frame attaches to your LCD screen with a double sided adhesive. The Z-finder snaps on and off to the flat frame very quickly.
The Z-Finder also has optional rubber bands, Z-Bands, to hold the Z-finder in place. The Z-Bands are just a security measure to hold the z-finder in place in case of accidental bumping. The Z-bands are an option and can be added below. The Z-Bands cannot be used without the snap fit frame! We also added a lanyard hook on the outside of the Z-Finder so you can attach a Zacuto lanyard to your Z-Finder. This allows for the user to quickly take the Z-finder off and on when needed. The lanyard hook and lanyard is included with the Z-Finder.
