Nine-Years Ago (08-March-2008) — Colorado

I must have been bored, so did some autofocus testing with some of my lenses. The goal was to see which lens was able to focus on Alexander Hamilton, and provide a sharp enough image to make out the microprint security feature on his shoulder. All of the images were taken with a Nikon D300 camera. The lenses used include a 105 mm f/2.8 VR macro, 200 mm f/2 VR, 300 mm f/2.8 VR, 400 mm f/2.8, and 200-400 mm f/4 VR.
