The simple 7-elements, 5-groups lens construction utilizing a short zoom lens design method achieves a brightness of f/2 in a lightweight and compact design. This efficient lens construction combines with a multi-layer coating treatment to achieve very clear imaging performance with virtually no ghosting or flare. The minimum focusing distance is 0.25m/0.8ft.‚ the shortest in its class- making it possible to take close-ups at a magnification of 0.23x, despite the wide angle of the lens.
