canon Serena 35mm F3.5  M39 Screw Mount Lens with caps(top cap is little loose but works) . Optics are decent with light dust specs and I can see some fogging inside and usual light wipe marks aperture work fine but oil on blades and focus works fine.Overall in a decent shape with some  wear.Selling As is . You need to get it cleaned lubed and adjusted to make use of it.
