Panasonic ET-ELW21 0.8 :1 fixed zoom lens for PT-MZ880/MZ770/MZ670 Series, PT-EZ770 Series, PT-EZ580 Series and PT-EZ570 Series projectors

Product Overview

The Panasonic ET-ELW21 is a 0.8:1 fixed short-throw lens for compatible Panasonic commercial projectors. Its short throw ratio places a large image on screen from a very close projector-to-screen distance, which makes it well suited to tight rooms and rear-projection cavities where mounting depth is limited. As a factory Panasonic optical assembly, this short-throw projector lens is matched to the lens mount and engine of its supported PT-MZ and PT-EZ series projectors. It is a fixed-focus design intended for permanent installations with a set geometry.

Product Description

The ET-ELW21 delivers a 0.8:1 throw with an f/2 aperture and a 13.05mm focal length in a compact ø4.3 x 6.5-inch barrel weighing about 2.4 pounds. Panasonic notes the lens is well suited to rear projection, where a short throw lets the projector sit close behind the screen in a shallow cavity. Because it is interchangeable, AV designers can re-lens a compatible projector for a short-throw or rear-projection room rather than buying a new projector. For longer throw distances on the same projector families, compare the near-standard Panasonic ET-ELW20 (1.3–1.7:1) and the long-throw Panasonic ET-ELT22 (2.7–4.5:1) and ET-ELT23 (4.4–7.1:1).
