I am not sure that I understand. Xume system consists of a lens adapter and a filter adapter. In my experience, normal lens cap doesn't fit over the Xume lens adapter. Which adapter does your regular lens cap fit? That's why Xume makes a special lens cap for their 77 mm lens adapter, but unfortunately not the other sizes.
Have you tried snapping the cap on the filter adapter? Believe me, it works. Hope this helps.
