Problem 2 Sandesh Kudar, National Geographic fellow and nature photographer, is taking pictures of distant birds in flight with a telephoto lens. (A) Assume the birds are very far away. Using your knowledge of the thin lens equation, what should the distance between the lens (objective), which has a focal length f, and the image sensor of the camera be? Remember that an in focus image must be formed on the image sensor to get a clear picture. (a) More than one focal length, f, away. (b) Less than one focal length, f, away. (c) Exactly one focal length, f, away. (B) As the birds move closer, will he need to increase or decrease the separation between the objective and the image sensor to keep the picture in focus? Justify your answer. Hint: A ray tracing may be helpful.
