The Lumix G X Vario PZ 14-42mm is a member of Panasonic's new premium “X” series. It is probably the smallest zoom lens in the whole industry. However, this compactness is achieved by a trick - out of the box (in its "transport position") the lens is not ready for shooting - it needs to be extended to its working mode similar to a digicam lens. Nevertheless, in working mode it is still shorter than e.g. the directly competing Panasonic G 14-42mm f/3.5-5.6.
The compact allrounder offers an equivalent focal length of about 28-84mm in full format (35mm) terms. The lens is offered both as part of camera-lens kit and individually. In the latter case is available for around 350 Euro which is certainly a bit expensive for a lens in this class but its "pancake" style character just doesn't come for free.
