Tonight's a special night — the closest full moon since 1993. So I wandered outside to take the best shot I could. I shot the one below with my 100-300mm lens at 300mm, f/8, with a cheap-o Quantaray 2x teleconverter at ISO 200, 1/250.
I used Live View on the 5D Mark II — at 600mm, it was tough to focus, because on my crummy tripod the image was bouncing around like crazy. Sharpening was applied. I chose the 10-second timer because it took a good 7 seconds for the lens to stop bouncing.
On my way home from work I drove up an access road near the airport and snapped the one below, hand-held at 300mm, ISO 3200.
