On a cold and clear day in Anchorage, Alaska this March I spotted a contrail in the sky that was heading in my direction. When it came closer I noticed 4 contrails and so I knew it was a larger airplane. I grabbed my camera with the telephoto zoom lens and tried to catch that plane. With full focal length of 400mm I needed to stabilize myself and the camera. Since I usually do not carry a tripod with me when I'm on vacation I lent myself and the lens to my car. Together with image stabilization I got a quite still image. Later on in post processing the image at my computer I was amazed, how detailed the shot came out. You can not only see that it was an Airbus A380, but you can clearly spot, what Airline that was: Korean Air. Very impressive, if you keep in mind that the airplane was flying at about 38.000 feet or 12.000 meters.
I took this photo with my EOS 70D camera and my excellent EF 100-400mm f/4.5-5.6 L telephoto zoom lens. The camera was set into P mode and calculated aperture and shutter speed automatically. ISO was at a fixed value of 400. I've chosen this high value to get a higher aperture value and faster shutter speed for a possibly sharper image.
