Telephoto lens that is ... I would consider trading my low actuation EP-3 and barely used 40-150 for the right large aperture manual focus telephoto lens. Probably would want either a Canon or Nikon and would prefer f/4 or less. Of course the optics would need to be in good order. Exterior appearance not all that important. My camera and lens would include all boxes, battery charger, cords, etc.
