Tamron SP 3.5-4.2/28-80mm Adaptall2 tested on a Sony A7III + analogue film cameras Canon F1n and T90

Once again I have connected a Tamron SP Adaptall-2 lens to various cameras for you and photographed and tested the lens with these digital or analogue camera-lens combinations for you.
This time I took a closer look at the Tamron SP 3.5-4.2 28-80mm Adaptall-2 standard zoom from 1979.
The basic idea of this lens series, which Tamron first introduced in the mid-seventies, is the uncomplicated adaptation to any camera bayonet. This is made possible by an interchangeable system ("Adapt-All" - suitable for all camera models), in which the lenses do not have a fixed mount, but can be easily changed by the user and thus adapted to different camera mounts on the lens side.
In this way, the photographer can simply take his lenses with him when changing systems and adapt them using different Adaptall-2 adapters.
From 1979, the first generation of Adaptalls was replaced by the Adaptall II series. Externally hardly distinguishable from each other, almost all Adaptall-II were completely new lens designs and had, for example, better coatings. In parallel, Tamron established the Adaptall-II SP series (SuperPerformance) with lenses from 17 - 500 mm focal length and three teleconverters. Most of the Adaptall SPs can compete with even the most modern lens designs (such as the SP 2.5/90mm Macro or the SP 2.8/300mm).
Above all, the SP's are built to last - solid, high-quality metal constructions that (unless they have been badly abused) still run as smoothly and free of play as the day they were made.
The value and feel of the lenses, coupled with their above-average optical performance, convinced me even back then and made me a fan of the SP lenses.

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.

Good video. What rubber care compound did you use for the hood?

Thanks for your comment. I use rubber care products from Nigrin.
