My current bike had a shimano ultegra bottom bracket with an english thread.

I'm buying a new frame with a press fit BB30. I've been told I need an adaptor to use my shimano hollowtech but can't work out which one.

Can I just buy a bb30 press fit BB, say sram etc and put that in or do I need a shimano press fit one. Or is is something else.
