Olympus and Panasonic have announced a new, mirrorless format / lens mount based on (and compatible with) Four Thirds. The Micro Four Thirds system uses the same sensor size (18 x 13.5 mm) but allows slimmer cameras by removing the mirror box and optical viewfinder. The new format has three key technical differences: (1) roughly half the flange back distance (distance from mount to the sensor), (2) a smaller diameter lens mount (6 mm smaller) and (3) two additional contact points for lens-to-body communication (now 11 points). Removing the mirror mechanism allows this shorter flange back distance, meaning lenses for the new mount can be considerably smaller than current Four Thirds designs. The format will require framing to be carried out using Live View on either the LCD monitor or an EVF. Existing Four Thirds lenses can be used on Micro Four Thirds cameras using an adapter. Neither company is as yet making product announcements (we expect some more news in this respect closer to Photokina).
Phil: This is without doubt the most exciting digital photography announcement this year. It's fair to say that this "extension / addition" to the Four Thirds standard is finally able to deliver on the original promise of that format; considerably smaller and lighter lenses and bodies. Olympus are however keen to stress that this in no way replaces Four Thirds which will continue with new Four Thirds bodies and lenses in the future.
While continuing to develop Four Thirds System interchangeable lens type digital camera system products, Olympus Imaging will also develop a range of Micro Four Thirds System lenses and accessories, and Micro Four Thirds System camera bodies that are even smaller and slimmer than the light, compact, and widely acclaimed Olympus E-410 and E420.
dpreviewThe adapter essentially restores the Four Thirds 40 mm flange back distance and provides electrical 'pass through' of the lens-body contacts. [portanto no crop factor]
Isto vai ser brutal (principalmente) para as massas/mainstream, imagino sairem daqui umas p&s super hi-tech com sensor "gigante"
