The Dynax 9 needs to be modified by the Konica Minolta Repair Center, because the SSM lenses use their own AF motor instead of the AF motor integrated in the camera body. This is the reason why the main electronic system of the camera needs to be changed. When purchasing a SSM lens, you will receive a voucher for a free modification of ONE Dynax 9 at the Konica Minolta Repair Centre. It is also sufficient to send in a copy of the receipt and the guarantee card of the lens. After the modification of the Dynax 9 it is also possible to use ADI flash metering in combination with SSM/D lenses. This is available with the built-in flash and the program flashes 2500 (D), 3600HS (D), and 5600HS (D)
