I don't know the lens, but I would nearly say "off course it asks for the focal length". It's an older manual focus lens by the looks of it and there (not surprisingly) don't seem to be contacts on the mount to communicate focal length with the camera.
It's probably only a bad purchase if you expected autofocus.
PS
The lens says KR which implies the 'Ricoh pin'. Be aware that some lenses with the Ricoh pin might get stuck on the camera. As you have tried it and I assume it came off again, it seems to be the harmless version of the Ricoh pin; there is also a 'dangerous version'. Just something to pay attention to the next time that you buy an old lens.
