    Overview

    The Olympus 40-150mm F3.5-4.5 is a compact, lightweight telephoto zoom (80-300mm equivalent) designed for affordability. Optically, it delivers excellent sharpness when stopped down, but softens at maximum aperture, especially at 150mm. Chromatic aberration is low at wide angles but becomes high at the telephoto end, and geometric distortion is slight. Build quality is good for a budget lens, with a metal mount and smooth zoom ring, though autofocus can be loud and slow. It suits amateur photographers seeking a low-cost telephoto for general use, but not for demanding low-light or fast-action work.
