absolutely satisfied 9

Initially I was concerned because some reviews pointed to strong production fluctuations. However, since I wanted to pay 800 euros for a Sony lens, I tried my luck and am fully satisfied to coincide with the first Tamron telephoto Amazon now. The vast majority of photos are very sharp, look for slight concessions only when full 300mm. At 250mm but absolutely top! The autofocus is fast and quiet, but needs clear contrasts and sufficient light. The Tamron 70-300 is doing very well as a portrait lens (people, plants, animals, ...) because of the background nicely blurred with appropriate zoom.
