Does this mean vile P&S's will finally be killed off?
"Rich" wrote in message ... dpreview.com: Olympus / Panasonic announce Micro Four Thirds Tuesday, 5 August 2008 05:00 GMT 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. Micro Four Thirds facts and features * Same Four Thirds sensor size (18 x 13.5 mm) * Flange back distance half that of Four Thirds (20 versus 40 mm) * Lens mount diameter 6 mm smaller (44 versus 50 mm) * Contrast Detect AF is implied (passive would require an external sensor) * Lens to body electrical contact points up to 11 from 9 * Lenses of same focal length and maximum aperture considerably smaller than Four Thirds * Enables slim and compact lens-interchangeable digital cameras * Lack of mirror well necessitate a high quality EVF (or an EVF/ Viewfinder-less design) * Current Four Thirds lenses can be used with an adapter Far from being the end of point and shoot cameras, I'd say it means better ps products as the technology migrates...
