Yesterday Olympus announced two new Micro Four Thirds lenses, the compact M.Zuiko Digital ED 9-18mm f/4-5.6 covers an angle-of-view range equivalent to that of a 18-36mm superwide-to-wide lens on a 35mm body, while the M.Zuiko Digital ED 14-150mm f/4-5.6 can be likened to a 28-300mm lens in 35mm equivalency.
While today Olympus announced a Micro 4/3 Lens Roadmap, which mentions both the lenses above as well as four others planned for spring 2011.
So if you're an Olympus user the future looks good in terms of new lenses available to you soon.
