Vivitar 35-85mm f/2.8: Something Screaming 'cross Your Mind

Green slaaaaaahm! A while back I had a look at the Vivitar 70-210mm f/3.5 Series 1, an old lens from the 1970s that was part of Vivitar's posh range. The company made a bunch of Series 1 lenses, which were accompanied by full-page adverts in the camera press which bigged them up as if they were the best thing since sliced cornflakes. The 70-210mm isn't bad, and I was curious about the others.
