PRAKTICAR 35mm f2.4 Lens by Carl Zeiss Jena. P/K Mount Bayonet. It is a bit scruffy. Could do with a service. There are two stubborn pin pricks on the front element. There is also a hair inside ( won't show up on any images ). Focussing gets stiff at the close up end. On offer way below any other of these. Worth getting CLA.
