One more example of Canon EF 100-300mm and tampon EF mount 28-80mm lenses with caps  in a decent shape . Focus works great, aperture opens and closes well and optics are in a decent shape with light dust specs and light wipe marks .  Lenses  take decent pics. Barrel shows some wear.

The Zoom on Tamron lens gets little stuck in the middle but works with an extra push, keep that in mind please!
