Original HOYA Back Lens Cap. You can mount it on any Canon FD series bodies, or of course any digital via a Canon FD adapter. It is quite fast as well, at F/3.5. D: Bad / Large Portion (Lens graded in this rank is still fully functional, however, it might benefit from cleaning and servicing. ).
Very good condition Hoya HMC Wide-Auto 28mm f2.8 wide angle lens with Canon C/FD bayonet mount. The lens has the popular Canon C/FD bayonet lens mount. There is very minor paint wear on the lens. The iris blades operate snappily.
One of my favourite lenses & I have one in my personal collection. There is very little wear to the barrel - just a little wear to the front of the built in lens hood. The lens is clear with no fungus & the iris operates snappily.
