Shown at left (click on image for a high resolution photo) is Tamron's Adaptall-2 lens line circa 1980. Nearly all of these lenses, along with Tamron's new SP lens line, were introduced in 1979. A few of these Adaptall-2 lenses were simply cosmetic redesigns of earlier Adaptall lenses, but most were completely new optical designs which also required completely new mechanical designs. While a few of these Adaptall-2 lenses are less than stellar optical performers, they all were very well constructed and were built to last.

Several of these Adaptall-2 lenses feature very good optical performance. The 24mm and 28mm wide angle lenses, for example, have somewhat above average to above average optical performance. Adaptall-2 zooms with above average optical performance include the 28-50 zoom lens, both 35-70 zoom lenses and the latter model 70-150 zoom lens. The latter model 75-250 and 80-210 zoom lenses provide above average optical performance as well. One lens to avoid is the earlier 70-150 model 02A two-touch zoom lens since this lens is simply a cosmetic redesign of the earlier Adaptall lens which had mediocre optical performance.

Adaptall-2 Lens Index

Lenses are sorted by focal length. Fixed focal length lenses are listed first, followed by zoom lenses.
