The Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. from Panasonic is an 85mm-equivalent lens designed for the Micro Four Thirds system of mirrorless cameras. One aspherical element is incorporated within the optical design, which helps to control spherical aberrations and distortions for enhanced sharpness and accurate rendering. Further cementing its place as a versatile tool for portraiture, the rounded seven-blade diaphragm produces a smooth out-of-focus quality when making shallow depth of field photos and movies. The POWER O.I.S. (Optical Image Stabilizer) also benefits hand-held use by compensating for the effect of camera shake for sharper imagery. Fast f/1.7 maximum aperture enables extensive control over focus position and also benefits working in difficult lighting conditions. Stepping AF motor and internal focus design provide smooth and quiet focusing performance and functions at a 240 fps signal transfer rate for fast, responsive use. Rounded seven-blade diaphragm produces a smooth out-of-focus quality when working with selective focus and shallow depth of field techniques.
