As I said, straighten filter ring while on the lens. If done slowly you
will have no problems and ring will be round again. This may seem risky
but I have done it regularly for 30 years. To remove a name ring with
no notches (I've seen some with only one notch (!)) you would use a
rubber stopper (like a fresh drain plug of the proper size). Inside of
plug would have to be concave so as not to rub on the front element.
