The super wide-angle M.ZUIKO DIGITAL ED 9-18mm F4.0-5.6 zoom lens (35mm equivalent 18-36mm) offers a 100 angle of view, and overturns the rule that super wide-angle zooms have to be big and heavy. With a length of just 49mm and a weight of just 155g, it less than half the size and 60% of the weight of the ZUIKO DIGITAL ED 9-18mm F4.0-5.6. With its wide angle of view, it makes it easy to include background scenery in group photos, and can be used to create unique images with a sense of dynamically exaggerated perspective.
This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.
