The Zacuto EVF is a 3.2” high resolution monitor that is used in conjunction with all the Z-Finder models. The EVF is compatible with all cameras that have an HDMI output including the Panasonic AF-100, Sony F3, RED ONE, RED Scarlet and RED Epic. The EVF allows you to operate the DSLR camera or any camera with an HDMI port, with the correct form factor for video with the camera in-line to your rod system (the most stable way) and your eye in the Z-Finder offset. This is the way all film cameras and ENG video cameras were operated and we, at Zacuto, believe this should be the way DSLR cameras should be operated. It will enhance the stability, give you better resolution, allow you to get your eye where it most comfortably needs to be, enable low mode shooting, shorten your camera package, have your EVF in the back of a dolly or crane, detached from the rig for car shots and more. The Z-Finder EVF is a complete EVF. It includes the EVF Snap model and an optical viewfinder which snaps onto the frame on the monitor. The optical viewfinder contains high quality 2.5x optics with anti-fog shields. The anti-fog is extremely important for reducing fog. It does not have a diopter but will include the Zacuto Z-Finder Extender Frames. The Extender Frames will get the focus close but might not be exact as you can’t dial it in with a diopter like you can with our Z-Finder Pro models.
