The Power Zoom Adapter PZ-E1 is a compact, lightweight accessory designed specifically and only for the EF-S 18-135mm f/3.5-5.6 IS USM lens. It allows you to smoothly operate the zoom with a fingertip lever while shooting movies. It is ideal for capturing professional-looking documentaries, with the possibility of controlling and adjusting the zoom also via Wi-Fi. It is a solution certainly appreciated by videomakers, where the wobble created by the manual operation of the zoom could certainly create disturbances in the focus and quality of the video itself. This system directly recalls the manuality of a camcorder, even in an advanced manner thanks to the presence of certain settings that can be managed directly in the adapter (zoom speed).
