Easy fix. First unscrew the nameplate ring from the filter ring. The way to do this is find a rubber bath tub stopper that's just under 49mm in diameter. Press this plug onto the ring and unscrew it. Now you'll see three tiny screws that hold the filter ring onto the main body of the lens. At least two of them will be loose. tighten all three and then screw the nameplate ring back in with your bath tub plug and you're set.
