Canon 70-210mm f/4 FD zoom with 58mm filter thread. This is the FD version that fits Canon A series Canon T series and Canon F series. Has a single trombone style push/pull to zoom rotate to focus barrel. When extended to 70mm, the focus can be taken into macro mode.
mechanically excellent, optically few specs of dust here and there nothing to worry about. Cosmetically almost excellent, just one small dent on the zoom barrel and a sticker mark (will easily remove) and couple of scuffs here and there - nothing serious.
