Try this:

• Position three fingers evenly around the outside of the ring (so you can apply even pressure) like this:
  
                    
• Grip the ring as loosely as possible. If you grip the ring with a  lot of force and/or attempt to use tools to remove it, it likely won't  budge and you might damage it.
• Hold the camera steady with your other hand.
• Push the ring against the camera with a little bit of pressure.
• Turn the ring counterclockwise.
• Wear a rubber glove if the ring slips through your fingers.
