I led a very small group of great people to Brookside Gardens in Silver Spring, MD yesterday. It was just as great as I remembered it having not been there for a few years. Hundreds of loose butterflies in a glass conservatory just waiting to be photographed! I wore my bright orange shirt and at one point I had at least three big butterflies on me including the beautiful Blue Morpho.
I used my Nikon D800 and the Nikon 200-500mm lens. I found this combo to be nice though the minimum focusing distance of the heavy 200-500mm is somewhere around 86 inches. That made things a bit tight as I backed up a 7 feet away from the butterflies. When you are that far back people tend to walk in front of you. Optically I am very happy with the pictures with this combo. I found the stabilization of this lens was fabulous and even on this cloudy day I was able to get sharp images at 1/160s at 500mm. Techincally I should have been able to go even slower but why push things. I kept the ISO between 800 and 1600 on the full frame D800.
