context_page_description: Zuiko is a brand of optical lenses made by Olympus Corporation that was used up to and into the Four Thirds system era. The name Zuiko means 'Light of the Gods', using a character from the Mizuho Optic Research Laboratory, where the lens was developed, and a character from Takachiho Corporation, which would eventually become the Olympus Corporation.
  With the introduction of the Micro Four Thirds system in 2008, new lenses for that system started to be branded as M.Zuiko Digital.
context_section_description: To estimate the angle of view of Pen half-frame system lenses, the native focal length may be multiplied by a factor of 1.4 to obtain the equivalent 35mm focal length. For example, the 20mm Pen lens has an angle of view approximately equal to that of a 28mm lens for 35mm format cameras.
