Olympus calls this a portrait lens in its promotional copy, but it's really so much more than that. Lenses that simultaneously feature a light-hungry f/1.8 aperture and a 150mm equivalent focal length are rare, and are very much in demand by sports and nature photographers in particular. They are capable of delivering singular isolation of your subject from a distance, in low light. That's a neat trick, because that's precisely the situation that trips up lesser camera/lens combinations. With its elegant lightweight metallic construction and superb optics, ithis lens has the build quality to live happily in your camera bag, waiting for its opportunity to shine. And with the flexibility it provides, you'll find those opportunities come up a lot more often than you think.
