The consistently fast telephoto lens is characterised by its robustness and extremely powerful stabilisation. Up to 7 shutter speeds longer hand-held exposure are possible in combination with the Body IS stabilisation. A weather-resistant construction with a total of 22 lens elements including various special lenses ensures high resolution right to the edge with low distortion and edge darkening. The constant aperture of F2.8 with 11 blades ensures smooth defocusing from the point of maximum sharpness to the neighbouring image areas for impressive bokeh. Fast and precise focussing, including the focus clutch function, round off this telephoto zoom. With teleconverters, the maximum focal length can be extended to 280mm (1.4x, with DMW-STC14) or 400mm (2x, with DMW-STC20) super telephoto. The filter size is 82 mm.
