40–150mm · f/4–5.6
The Olympus M.Zuiko 40-150mm f/4-5.6 is a compact, lightweight telephoto zoom offering decent center sharpness but softer edges and corners. It is entirely plastic with a plastic mount, not weather-sealed, and feels cheap. Autofocus is reasonably fast and quiet, though it can wobble. Optical weaknesses include visible chromatic aberrations and softening beyond 100mm. It suits beginners or enthusiasts seeking an affordable, portable telephoto for travel or casual use.
