Enjoy a very flexible 2.10-4.14:1 throw ratio for your PT-MZ20K series projector with the ET-EMT750 2.10-4.14:1 Long-Throw Zoom Lens from Panasonic. The PT-MZ20K series utilizes interchangeable lenses to customize the size and distance to fit your space perfectly. The ET-EMT750 is designed for situations where the projector needs to be further away from the screen. When used in 16:9 or 16:10 aspect ratio, it sports a throw ratio of 2.10-4.14:1, meaning this lens can create a 20' wide image from 42 to 83' away. If used in a 4:3 aspect ratio, this lens has a 2.5-4.97:1 throw ratio. To fill a 20' wide 4:3 screen, the distance would be anywhere from 50 to 99.4'.
