Micro Four Thirds Cameras
Compared to existing, which are equipped with non-interchangeable lenses and smaller image sensors, Micro Four Thirds is intended to offer a compact solution with interchangeable lenses and the larger sensor used by Four Thirds DSLRs. Micro Four Thirds cameras are smaller and lighter than Four Thirds and DSLRs, but larger and heavier than compacts. [Read the full article at Micro Four Thirds system - Wikipedia.]
The Micro Four Thirds System
The biggest attraction of any SLR camera system is the ability to change lenses. However, if the imaging plane (focal point) varies depending on the angle of view or focal length of each lens, it would not even be possible to focus the subject. To avoid this problem, the imaging plane of all interchangeable lenses is standardized by strictly specifying the length of the flange back, or the distance from the mount plane to the film/image sensor surface.
Digital SLR cameras incorporate more components between the lens and the image sensing material than film SLR cameras, such as the image stabilizer, dust reduction mechanism and low-pass filter. Also, since the viewfinder of an SLR camera requires a mirror box for viewing the real image, the flange back needs to be longer to accommodate the mirror box. Compact cameras do not use the mirror box, so don’t require a long flange back. These factors have made it difficult to design SLR cameras that are as slim and compact as compact cameras.
However, if a digital SLR camera can be designed to exclusively use Live View for shooting, the mirror box is no longer necessary and the camera can be designed with the kind of slim profile previously considered impossible, without compromising the high picture quality. For example, when an ultra-slim pancake lens is combined with the camera, it can be stored and taken out of the inner pocket of a jacket, allowing the user to benefit from the high picture quality of SLR with a higher degree of freedom.
The Micro Four Thirds System is a new standard based on combining Live View shooting with the Four Thirds System, freeing users from the viewfinder and moving closer to an optimum balance between picture quality and compact size. With the Micro Four Thirds System, more people will be able to enjoy the excitement of interchangeable lenses and system extension capabilities that only SLR photography can offer, while still benefiting from the convenience and high portability of ordinary fixed-lens compact cameras.
