OM SYSTEM M.Zuiko Digital ED 40-150mm f/4-5.6 R Lens (Black) Review

The OM System M.Zuiko Digital ED 40-150mm f/4-5.6 R is a compact telephoto zoom designed for Micro Four Thirds cameras, delivering an 80-300mm full-frame equivalent focal range. At $170, it's positioned as an affordable entry point for Olympus and OM System shooters who need reach for travel, wildlife, or portraits without carrying heavy glass. The lens incorporates one extra-low dispersion element and one high refractive index element to control aberrations, while a rounded seven-blade diaphragm aims to produce smooth bokeh. Its movie and still compatible autofocus system makes it suitable for hybrid shooting.

The variable f/4-5.6 aperture is typical for budget telephoto zooms, trading maximum light gathering for lighter weight and lower cost. This lens fits cleanly into OM System's kit lens lineup as the natural step up from standard zooms for users who need more reach. It's a straightforward telephoto option that prioritizes portability and value over speed or premium optics.
