Power Zoom Adapter PZ-E1 is a detachable accessory designed for use with the EF-S 18-135mm f/3.5-5.6 IS USM lens. It uses a zoom lever similar to those found on camcorders, allowing for incredibly smooth zooming that may be difficult to do manually. Remote control function is available using smartphones and computers when used with an EOS 80D camera and Canon Camera Connect software.
