Olympus Micro Four Thirds Camera Views
MFT shares the image sensor size and specification with the Four Thirds system, designed for DSLRs. Unlike Four Thirds, MFT does not provide space for a mirror and a pentaprism, allowing smaller bodies to be designed, and a shorter flange focal distance and hence smaller lenses to be designed. Virtually any lenses can be used on MFT camera bodies using a right adapter. For instance, Four Third lens can be used with auto focus using the adapters designed by Olympus and Panasonic.
The MFT lens mount is specified to be a bayonet type with a flange focal distance of circa 20a mm – half as deep as the Four Thirds. The shallow camera body specified by the MFT standard precludes the use of mirrors, so the cameras use a live view electronic display (either on a large LCD screen or via an electronic viewfinder) or an independent optical viewfinder. The flange diameter is about 38 mm, 6m mm less than that of the Four Thirds system. Electrically, MFT uses an 11-contact connector between lens and camera (Four Thirds: 9 contacts). Despite this difference, Olympus claims full compatibility of existing Four Thirds lenses with MFT bodies, using an adapter.
The shallow but wide lens mount will also allow the use of existing manual focus lenses including Leica M and Olympus OM system lenses, via aftermarket adapters,[5] on MFT bodies. It has been suggested that the contrast-detection autofocus used by compact cameras and MFT requires powerful focusing motors and may not operate properly on at least some of the existing Four Thirds lenses designed for phase-detection autofocus.[6]
For the Four Third lenses that can be mounted on MFT bodies, see Four Thirds system#Four Thirds system lenses. For the Four Third lenses that support AF, see [2]. For those support fast AF (Imager AF), see [3]. As of October 2010[update], there are eighteen Micro Four Thirds standard lenses which can be used by both Olympus and Panasonic MFT cameras:
