The FS5 Z-Finder is specifically designed to convert the monitor included with the Sony FS5 to an optical viewfinder. The Z-Finder comes with a flip up frame designed to slide onto the FS5 LCD and lock securely in place. The Z-Finder can pop on and off the frame for quick shooting. This Z-finder will magnify the LCD screen by 2x and has a diopter for fine focus tuning. It cuts out any extraneous light helpful for outdoor shooting and offers an initial point of stability by pressing your eye against the large eyecup. The FS5 Z-finder comes with a 40mm diameter Zacuto designed optic, anti-fog coated protective lens, and the mounting system designed specifically for the FS5 LCD.
