Olympus 35mm Micro 4/3, Pen, OM-D Mirrorless Camera Systems
Olympus is one of the leading digital camera manufacturers
The Olympus range of mirrorless interchangeable lens cameras consists of two
primary designs. The OM-D line-up is modeled after the classic OM-1 film camera from the 1970s,
while the Pen range whose design was inspired by the original Pen F half-frame 35mm SLR cameras.
Although OM-D and Pen cameras use very similar technology, they are easily distinguishable by their design.
All OM-D cameras feature an electronic viewfinder inside a centrally placed hump while the Pen cameras either have an electronic viewfinder positioned on the left or more commonly, no viewfinder at all.
Olympus manufactures the most Four-Thirds lenses which are built using the Zuiko brand; which are renowned for their excellent optical quality and compact size.

Olympus developed its first camera body in 1938, in addition to building its own lens and shutter device, as this was the first totally pure Olympus (the Semi-Olympus II camera) it was an important event. The design which opened on the side of a pressed sheet-metal encasement was a unique feature on a medium-format camera. The camera also included a Galileo reverse tubular viewfinder.

Image Sensor Sizes
The full size Four Thirds system
was discontinued in 2013 replaced by the Micro Four Thirds System. Four Thirds
was a standard created by Olympus and Kodak for digital single-lens reflex camera (DSLR) design and development.
The system provided a standard that, with digital cameras and
lenses available from multiple manufacturers, allowed for the interchange of lenses and bodies from different manufacturers. U.S. Patent 6,910,814 seems to cover the standard.
it was claimed to be an open standard; it is however only accessible to companies and under a non-disclosure agreement.
Unlike older SLR systems, Four Thirds
was been designed from the ground up to be entirely digital. Lens design were tailored to the requirements of
digital sensors, most notably through telecentric designs. The size of the sensor is slightly smaller than for most DSLRs (see drawing) and this implied that lenses, especially
telephoto lenses, can also be smaller. For example, a Four Thirds lens with a 300 mm focal length would cover about the same angle of view as a 600 mm focal length lens for the 35 mm film standard, and is correspondingly more compact. That is, the Four Thirds System is said to have a
crop factor (focal length multiplier) of about 2.
