Only notation I'll add, is I had the mentioned lens & used it with a tripod that supported 25 pounds. The issue I had, is the hood for the lens was so long that with a steady wind over 5 mph, I had vibration. In addition, I added 10 pounds of weight to the tripod, No difference. I ended up selling the lens & purchased the 500mm f/5.6E PF ED VR Lens
Yes, wind has a habit of catching the long hoods.
When that happens...take off the hood.
If need be...use your hand to block any flare angles.
