Initialization of Techart EF-GFX adapter
The firmware v2.0 requires initialisation at first connection. The camera has to save the parameters of your lens in the first connection. The lens will run a full focusing from closest to infinity automatically after connected. (it normally takes less than 5 seconds). Please do not disturb or press any buttons during this initialization process. Once the camera has saved the parameters of the lens in the first connection, no further initialization is needed for the same lens. This initialization will repeat itself when a different lens is mounted onto the adapter.
