The Z-Finder Pro 2.5x for 3.2" Screens from Zacuto is an optical viewfinder that videographers may find necessary for shooting sharp, stable video on DSLR cameras like the Canon 5D MkIII, Nikon D800, or others with the same size LCD display. Whether shooting handheld or on a tripod, the Z-Finder Pro turns your camera's 3.2" LCD screen into a clear, easy-to-focus viewfinder that lets you see your image in magnified detail, even under the brightest sunlight. Just as crucially, the Z-Finder Pro provides an extra degree of handling comfort and a crucial point of contact--between camera and eye--that adds stability to any handheld video.
