This 3x zoom lens for Micro Four Thirds system cameras, provides a field of view equivalent to a 24-70mm lens on a 35mm camera. It also sports optical image stabilisation, a silent focusing motor and a lightweight, compact design. The maximum aperture remains constant at f/2.8 throughout the zoom range.
This lens feels very solidly built, despite being lightweight and compact. It is constructed from high quality plastics, that have a dark grey gun-metal finish and the lens mount is made from metal. Even though this lens has a constant f/2.8 maximum aperture, it only weighs 305g, which makes it feel right at home on even the most compact Micro Four Thirds camera bodies, such as the Panasonic Lumix GF3 used for testing. The lens is designed to be resistant to dust and moisture, making it suitable for using in inclement conditions.
