issues when used on Olympus OM-D cameras

  • it seems that some of these lenses are depositing substantial amounts of metal dust into the camera body due to the lens mount - seems to be related to whether there is a rubber weatherseal or not, as some of those with the seal seem to have an issue - Panasonic seems to be offering to replace the lens if it has this issue
  • as with all Panasonic lenses on Olympus cameras you will lose some features:
    • Dual IS / Sync IS is not supported
    • ProCapture mode is not supported
    • Auto Focus Stacking is not supported
