Vivitar 75-205 f/3.8 with matched 2x teleconverter. Manual focus, preset aperture.
There is some minor wear and brassing and on the body, but nothing unusual for a lens of this age. The glass is in very good condition - there are some tiny spots on the coating which do not affect IQ at all. Aperture is snappy and oil-free. Lens comes with original front and rear caps.
The teleconverter is in like-new condition, only used twice. It comes with all the original packaging, caps, and leather case.
