Probably the same as my Kiron 80-200mm f4, after many test it was equal to my Canon FDn 200mm f4 prime for sharpness....so the Canon stays at home as the zoom is more useful and only slightly longer than the canon.
I can't comment on your particular lens Jeff because I've never used one although I used to sell them in my store, I do have the Canon FDn 80-200f4 L zoom which is a pro quality optic,and is indeed a very good lens that still sells for very good prices on the used market, however I.M.O. the Vivitar Series1 70-210 that was specifically commissioned by Vivitar to compete with the best lenses the marque camera manufacturers could produce at the time, and manufactured by some of the best Japanese optical firms is IMO better than my canon one which cost a lot more on the used market these days.
I bought my Vivitar series 1 in mint condition from a local camera shop boxed with the original rubber hood for £40 (about $65 US) with six months guarantee, there aren't any lenses of that quality available for that sort of money on the market, and the Vivitars are selling for very low prices these days.

Well I just won a Canon EF and 50mm f/1.4 SSC on a whim, not sure what the real condition is, but it didn't cost much so maybe it'll be a nice surprise
Was this the one at Goodwill? I dropped out just because I already had an EF and a 50mm f/1.4 but thought I could get one on the cheap. You still got it for a nice price even though the S&H was a bit too much I think.
