Overview

The Revuenon 240mm f/4.5 Auto, manufactured by ENNA MUNCHEN in the 1960s-70s, offers respectable optical performance even wide open, though its four-element design does not excel in image quality compared to a Nikkor 180mm f/2.8. The lightweight polycarbonate barrel feels solid, and handling is easy with comfortable controls, but the lens lacks automatic diaphragm closure. It suits photographers seeking a compact, affordable long lens for casual use, though finding one may be challenging.
