It's a Vivitar 75-205 mm f/3.8 Macro focusing zoom. In this picture, I believe it has an attached 2x teleconverter and, consequently, reduced image quality.
The Vivitar 75-205mm was apparently a very popular lens for advancing amateurs a generation ago, and was well loved by many of its users, though weaker at extremes of f-stop and range than today's equivalent lenses.
It can be readily found on e-bay today for $30.
Not bad. It's essentially a 70-200mm F/4 (but better). It was probably worth something back in the day, but since it's manual, times have changed.
My experiments so far with the manual lenses really highlight now inconsistent autofocus can be. It's great at getting fairly sharp, though it needs light on the subject and creates a delay when you press the shutter button. Yet for getting *razor* sharp, it's as inconsistent as manual. I can take 10 pictures on a tripod and observe sharpness differences in most of them.
Probably I just haven't figured out yet how to use the AF right.
