Got an Olympus E-System DSLR? Having trouble with focusing accuracy when using the EC-20 teleconverter? You'll be needing one of these new firmware updates then. Users of the E-1 through E-510 can all benefit from this round of tweaks, with the E-510 receiving an extra bonus in the form of improved Image Stabilization at slower shutter speeds. As usual the firmware is updateable via your Olympus software - Master, View or Studio depending on your model.
