I have AT-X 28-70 PRO f/2.6-2.8, purchased back in 1997, which I believe is the previous version of this. This is a very good lens, and at that time it was tested very well against other brands. I don't remember details, but my impression that it was rated just below the counterpart from Pentax, and way above the similar lenses from the Sigma and/or Tamron (I don't remember who had what at that point). Overall, my lens is very good. I think it a bit soft on with the aperture one open, but half a step closed down it seems to be alright. It is rather heavy and large in size, but to me it is worth hauling it around. With ZX-5n and *ist DS it is usually quick to focus (if the manual focusing ring is disengaged). Maybe not as fast as my Pentax SMC FA 50/1.7, but, still fast enough. Again, I am not sure how the new lens is compared to the old one, and what is the difference between the 28-70/2.8 and 28-80/2.8, i.e. which one is the continuation of the 28-70/2.6-2.8 design, if any. I was curious about that myself. Igor
