Panasonic Lumix G X Vario PZ 14-42mm f/3.5-5.6 Power O.I.S. Lens (Black)

Panasonic's Lumix G X Vario PZ 14-42mm f/3.5-5.6 Power O.I.S. Lens (Black) is a super compact retractable pancake 3x zoom lens (28-84mm equivalent in 35 mm and full-frame formats) for Lumix Micro 4/3 cameras that's only about the size and weight of the 20mm pancake lens. It's 2.4 x 1.87"/61 x 47.7mm (the short dimension shrinks to 1.05"/26.8mm when the power is off). It weighs just 3.35 oz/95 g. Not only is it small and light, this X lens has high performance specs like electric-powered zoom operation, autofocus during movie recording, nano surface coating that drastically reduces ghosting and flare, and Power O.I.S. (Optical Image Stabilization) for greatly improved image sharpness and blur reduction. Two ED lens elements compensate for chromatic aberration, and the silent design makes this an ideal lens for shooting video.
