Canon 1Ds Mark III, 700mm (500mm f4L IS with 1/4x) 1/640 sec @ f/6.3, ISO 400
Super telephoto lenses are great for tight landscape photos. I use my 500mm all the time in this manner. This was a grab shot from the window of a car after seeing the sun in the rear view mirror. The thin veil of clouds soften the suns power enough to allow for a balanced exposure. The clouds moved quickly so the shot needed to be fast and thanks to a bean bag quickly thrown on the car window ledge, I snagged a few compositions. I happened to have a 1.4x converter on the lens from a previous shot which proved sufficient since I did not have time to remove it before the clouds obscured the sun.
