Image: 50D, 300 f4 IS L, 1/800 sec at f 7.1
Isolating mountain peaks with a telephoto lens is a type of landscape work I enjoy a lot, it gives a sense of what its like up there, and allows you to compose some interesting and original work. This can be shot at wider apertures than the typical landscape due to less depth of field, these type of images also lend themselves well to black and white renditions, the 300 f4 IS L is a very nice lens and pretty versatile, I was shooting Buffalo in the morning with it and the Teton range later that day. The above shot was converted to b and w with CS4.
