Panasonic 20mm Filters and Step Rings

Hi, anyone know how many 46mm Filters can be stacked on the Panasonic 20mm before vignetting occurs?

Also anyone had success with cheap step rings from China? I have read reports that they can catch the lens and cause problems and its best to use a 46mm extension. But I would like to cut the extension out if possible and have less bulk on the lens.

Cheers

I don't use 46mm filters. I have a 46-49mm stepping ring and use Cokin P filters. I chose the 49mm size so I could use an old Olympus 28mm lens hood from time to time.
