The adapter allows you to modify the list of lenses so that the EXIF data matches your lenses. It provides focus confirmation and it's about the same weight than the TTArtisan, but it doesn't have a reader for the 6-bit code. To choose a lens you select an aperture smaller than f/10 using your camera dial and cycle power. It also works as a close-focus adapter.
