Camera guys - need help with a device
 

I have this camera part. It has "Mount Adapter for HB-CF" embossed on it.

Does anyone know what this thing is for? I assume that HB and CF are the type of lens that it will work with. Also, what is the bellows for? The bellows detaches from the mount adapter just as a normal lens would.

One end of the adapter fits my Canon, but I have no idea what the other end goes to.

Thanks

Not totally sure I think it might be 2 separate pieces. The mount adaptor is for a Hasselblad camera, looks like standard (PL?) bayonet mount. The extending bellows could be a part to increase focal length, or extend minimum focus

Yes, the two separate. Just wondering what HB and CF mean. You're correct the two don't go together neccesarily.
