The ebay seller uses EMS to ship goods and it's a great service and only takes three days for items to arrive. Even our Cairn Terrier, Sam, was anxiously waiting for the Postman to drop off the package. He couldn't care less about the GR adapters, but he knows the postal carrier always has treats.
Since there's very little info about these adapters,
here is a snapshot of the packaging.
Here are photos to show what both adapters look like on the GR.
Here are photos of the .75x wide conversion lens...
Clearly the added weight and size of the GH-3 Adapter and the .75x Wide Conversion Lens GW-3 changes the compact size and great ergonomics of the GR. Here are a few photos to give you an idea of the relative size of the GR and Adapter/Lens in your hands.
