The first Micro Four Thirds lens from Leica consists of 14 lenses in 10 groups, using both an aspherical lens and an ED lens to realize outstanding compactness and light weight while minimizing distortion and chromatic aberration. It incorporates an inner focus system of 3 groups of floating structure, which enables excellent resolution and contrast without changing its overall length from full life-size magnification to infinity. Panasonic's Mega O.I.S. (Optical Image Stabilizer) prevents hand-shake, making it easy to shoot clear and sharply focused macro shot or when shooting in dimly lit places without using a tripod. This lens also excels in portraits, mid-range snapshot, or landscapes in addition to the original 1x macro shots.
