This is a Canon forum but here goes, the adapter screwed up the focal plane.  You will probably have to be very close to focus on anything.

At f/1.2 your focus will be a very narrow plane. Is there *anything* in focus?

I just can't get sharp focus with the cannon lens on the Fuji with adapter  

it is not bad but not as sharp as I would expect

It is the cannon 1.2 lens! It is not in focus however close I get

If you are using f/1.2, then you dealing with a VERY narrow Depth-Of-Field.  It can get extremely narrow.

You can try to take the lens to a camera shop, and have them test it.  I'd bet that the lens is working properly.

Not easy in the Highlands!

Adapters are for fun, or marketing. It is almost always the case that it will degrade lens performance.

Thanks, that is probably it!
