M.Zuiko prime lenses feature fixed focal lengths ranging from the 12mm F1.8 lens that's optimized for landscapes to the 75mm F1.8, a perfect portrait lens.
Photographers who shoot a lot of portraits and still-lives are always seeking good bokeh.
You’ve seen a lot of professional-level photos with sharply rendered subjects and artistic defocused backgrounds.
One of this lens’s most interesting features is the unique-to-Olympus Movie & Still Compatible mechanism, or MSC. This technology provides amazingly fast – and nearly silent – autofocus operation.
