j'ai lu ceci sur Tamron 70-300mm f/4-5.6 Di VC Lens Review
However, I need to add a possible warning that these results do not tell the complete story in this case. I had to spend a more-than-usual amount of time focus testing this lens - just to confirm what I was seeing. And my initial (still early) determination is that my Tamron 70-300mm f/4-5.6 Di VC Lens is very inconsistent in the focus accuracy department. Life is good when it gets focus right, but a sharp lens does not deliver sharp subjects if not focused accurately.
il semblerait que coté AF ce soit "très instable" !!!???
