The Panasonic Lumix G X Vario PZ 14-42mm is a zoom lens in the Micro Four Thirds system.
An unusual feature is that the lens collapses to pancake size.
To do so, focus-by-wire and power zoom are manually controlled by two thumb levers, not grip rings.
Panasonic's "HD" branding indicates focus and zoom motors are quiet, for videography.
The optics contain Panasonic's "nano surface coating".
