This has the same construction and exterior design as the EF 35-80mm f/4-5.6 USM lens. The optical system is also similar. Instead of having a USM, it has a micro motor
The EF lens 35-80mm f/4-5.6 III is a remarkable light and compact zoom lens.
At 175g this is the lightest compact zoom EF lens. An excellent value. The aspherical element makes it compact and helps obtain high-contrast images. At the 80mm focal length, a postcard can fill the viewfinder frame.
