Agreed.
My understanding is that the four-thirds lenses aren't dramatically smaller than the full-size lenses for two reasons:
1) (self-inflicted) The fact that the four-thirds standard called for parallel light rays hitting the sensor, to improve digital image capture, and
2) (simple geometry) The flange depth is as important to the overall lens size (amount of glass, distance from camera, etc) as the size of the sensor.
With the
micro four-thirds format, the second issue is basically resolved by creating a new flange depth that is proportionate to the smaller sensor size. That's why our new lenses can have much less glass, and be much lighter than the equivalent full frame lenses.
The original Leica D lenses were hampered by having to fit the deeper four-thirds bodies. One strategy would be simply to make them
longer, effectively adding in the adapter to the length of the lens. What I hope they do, instead, is to scale down the entire lens design to match the new sensor/flange depth geometry, which would result in a really small lens, even if it has a very large maximum aperture.
Make the whole lens smaller
