Originally posted by falconeye Thanks. From what I can make out, looks like the focus is on accomodating weather-resistant lens rather than any revisions to the optics (sorry, creampuff).
Seems to be a slight revision of the mount on the body -- basically the same mount with one key difference -- the flange of the mount on the 1st body is wider than the flange of the mount on the 2nd body.
They describe:
- A lens with a sealing ring that presses against the mount on the camera body for water resistance.
- A 1st body (the "compatible" body) which is built taking into account the pressure exerted by the lens sealing ring, so that the optimum lens to sensor distance is maintained.
- A 2nd body (the "incompatible" body) where the lens would connect to the body with the sealing ring not coming in contact with the body mount. Thus maintaining optimum lens to sensor distance, but no water resistance sealing.
They explain that the reason they are doing this is that the 2nd body was not designed to take such lenses, so the pressure of the sealing ring on the body mount would throw the lens to sensor distance off the optimum.
Presumably, the 1st body is the future we are looking at.
Other patents they have filed for:
- Improved anti-shake mechanism (
US patent application 20080298790)
- Improved motor in SDM lenses (
US patent application 20080297003)
- Miniaturisation of the viewfinding system (presumably for the K20D-type camera because it describes the use of a prism) (
US patent application 20080232791)
