Use a better filter. I haven't had a problem like that at f/1.4 nor f/1.7.

Any filter will give the problem if the conditions are extreme.  No anti-reflection coating is perfect.

You give me the filter and I will find circumstances where it will give ghost images.  The filter must be mounted fairly close to the front element of the lens - the exact conditions depend on the lens design.
