With integrated optical stabilization of 4 stops of shutter speed, achieve sharp handheld images. This in-lens system also works in tandem with the in-body stabilization of select MFT cameras to create the 5-axis sync IS method, which further improves handheld shooting by compensating for up to 6 stops of camera shake. Three Super ED lenses eliminate peripheral chromatic aberration, and three High Refractive index lenses and one Extra-High Refractive index lens ensures sharp imagery. Z Coating Nano reduces ghosting and flare. A near-silent movie-still compatible High-Speed Imager AF system makes this lens suitable for stills and video capture. 17 seals provide dust and water resistance for use in all-weather, and the lens is designed to work at temperatures as low as -10°F. Manual focus is available by simply pulling the focus ring towards you and enables fast switching between MF and AF.
