The Mamiya Sekor E 3.8/80-200mm (and its earlier cousin, the CS 3.8/80-200mm) are among the best telezooms from around 1980. An extensive test by Walter E. Schön in the German Color Foto magazine (around 1980 as far as I remember) gave excellent results for the Sekor 3,8/80-200mm. If I remember correctly, its detail resolution was second best among about twenty tele zooms tested.
The Zeiss CY Vario-Sonnar 4/80-200mm (which is from around 1990 and was calculated by famous Lothar Kölsch, later at Leica) is well known for its crisp and clear images even at fiull aperture, outperforming all other well known non-ED/AD/ULD/Fluorite zooms from Canon, Konica, Minolta, Nikon, Pentax, Olympus and Yashica alike.
I have compared the two lenses mentioned above, using the 24 MP FF sony A7II. Here are 100 % corner crops from the JPGs out of the A7II.

Now at f=200mm. Left image is wide open, right image at f8. Top line Mamyia, bottom line Zeiss:
And if you want a vintage tele zoom that has no CAs at f=200mm and f8: Go for the Mamiya Sekor C 4.5/105-210mm. It's a behemoth, though.
