Excerpt: This compact standard zoom lens for Micro Four Thirds cameras covers a range equivalent to a 28-84mm lens on a 35mm camera, sports a unique compact design and optical image stabilisation. It is currently available as a kit with the Lumix G1X camera and can be picked up on its own for around £370. It is unique because it uses motors to drive the zoom and manual focusing, and this design has allowed Panasonic to create a lens that is only 26.8mm deep when not in use.
Pros: Excellent sharpness between 14mm and 25mm, Compact size, Good build quality, Light weight, Effective optical stabilisation, Nano surface coatings help to reduce flare
Cons: Distortion at both ends of the zoom range, Pricey when compared to alternatives
