The Tamron SP lenses are all quite good optical quality and were bargains when new. This 28-80 zoom is excellent, however the 35-80mm zoom it replaced was even better. In fact, it was as good as the competing Nikkor at the time. The 35-80 was offered for less than two years. It was replaced by an inferior lens because the market demanded the wide zoom reach to 28mm, so all makers were making this change at the time.
Many thanks for your comment. I really liked Tamron lenses back in the analog days. I will definitely buy the Tamron SP 2.8-3.8 35-80mm, model 55B, at some point if I find a good offer and then present it here.
