Apparently the top of this tree has an anomale named a “broom.” it’s when the tip of the tree gets all hard and the wood is bigger at the top than at the bottom.
I went to the Henry’s photo show this past weekend which proved to be a fruitless effort: 1.Henry’s is expensive 2. I spend hours a day reading about lenses so what can 5 minutes alone tell me about it what I don’t already know. 3. Sigma had a “booth girl” that you could take photos of to see how “great” their lenses are.
