After a bit more poking around on the web I'm wondering whether the problem could be the lens mount? The 18-55mm kit lens has a plastic mount as against the 50-200mm's metal mount. Could this be the source of the problem - contact not being made correctly? If so then I suppose it's the camera body that might be the problem, but I have no way of tesing the lens on another NX body.

In the firmware menu with the 18-55 attached I can choose to update the lens firmware with the appropriare lens.bin file but with the 50-200 attached that doesn't work. Even manual focus doesn't work so I'm guessing that the lens isn't getting power. iFn doesn't work either...

Your assumptions seem logical to me.  I would also suspect a contact problem. You might try cleaning the contacts on the lens with a pencil eraser and also ensure the lens is fully locked in place (you should hear a click as it locks).

Since the lens has iFn, it must be the latest model.  I would still expect its basic functions to work on your NX11 without updating the lens or body firmware.  You'll probably need the firmware updates to get iFn working though.   I could be wrong but I think the lens firmware is not specific to the body.  i.e. it should be suitable for any NX model.  I think it is only listed under NX10 for convenience rather than Samsung having to include it on their website separately under each and every model.

NX lenses have fly-by-wire manual focus so power and data connection is required even for manual focus.  If the aperture is showing as F-- the camera must be detectinng it as an adapted legacy lens, so again I agree with your conclusion that it is probably a contact problem.

If you manage to bring it to life, be aware that there is specific lens firmware for the iFn version of the lens compared to the earlier 50-200 versions.  You need to have the correct lens attached and the correct firmware on the card.  Otherwise the firmware upgrade option will be greyed out.
