It was a warm night and I got home early from a show when I noticed the Moon low in the sky. So I put a 1.4x teleconvertor on the big 300 mm lens and went out to photograph it. On my Canon 30D digital camera this combination of optics is equivalent to 600 mm on a regular 35 mm camera. I should have used a tripod, it was hard holding the camera steady with such an extreme setup. This is how it looked in the viewfinder. The technical details are: ISO 800, 1/2000 sec, f5.6, the equivalent of 600 mm using a Sigma EX 120-300mm f2.8 with a 1.4 teleconverter on a Canon EOS 30D.
