最後一點有提到,現行鏡頭可用轉接還轉接喔~只是光圈大小應該會再變化 不過這樣新的設計,幾乎就像是"可以換鏡頭的DC"了!!當然希望機械性能方面會比DC強上許多才會吸引人~~ 另外這樣新的設計,"錄影功能"加在Micro Four Thrids大概也不會令人感到意外囉
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).
無反光鏡, 現有 4/3 system 鏡頭可透過轉接環接上, 取景要由 EVF (Live View), 感光元件尺寸不變
