It was pretty windy today,so shooting anything organic was a challenge....lots of strong gusts all day long. To stop motion I selected f/4.8 and saw 1/2000,so I took this shot of these Douglas Fir treetops gently bending in the wind. The degree of detail resolution is pretty satisfying in the original 12 MP Jpeg. This lens is plenty sharp at f/4.8 at distance.
