Olympus Japan have released a firmware update for the E-3 body.  The update enables the use of the Image Stabilization function with non-Four Thirds System interchangeable lenses by inputting a specific focal length and also addresses the focusing which now stops immediately when the AF start button (AEL/AFL or Fn button) is released,  corrects the phenomenon where the flash control caused an under exposure while using bounce flash at short distances and a couple of other minor issues.

Enabled use of the Image Stabilization function with non-Four Thirds System interchangeable lenses by inputting a specific focal length. 

Matched the rotation of the dial on the rear of the Power Battery Holder HLD-4 and the movement direction of the AF target.

Increased the number of storable still pictures by improving the battery check when the Power Battery Holder HLD-4 is attached.

Focusing now stops immediately when the AF start button (AEL/AFL or Fn button) is released

Corrected the phenomenon where the flash control caused an under exposure while using bounce flash at short distances with the FL-50R or FL-36R Electronic Flash.

Improved selection and prioritization of the central 5 ranging points when shooting in C-AF mode and Dynamic-single Target mode.

By setting the focal length of the lens in advance, you can use the image stabilizer function with lenses
other than the Four Thirds system.
