Kenko announced two new 10mm and 16mm extension tube that fit in between the lens and the camera mount. It will transform any E-Mount lens in a macro lens! You can also use both extensions at the same time. The probably bigger news here is that it has electronic contacts to allow autofocusing and aperture control. The tubes will be available some time within April and cost around 216 Euro each.
I don’t know where you can buy Kenko stuff in local stores. I found some of their lenses and adapters on eBay (Click here).
