Problem
A wildlife photographer is trying to photograph a bird perched on a branch 15.0m away. She uses a camera with a converging lens of focal length f=85.0mm. However, she discovers that the camera's autofocus system is broken, and she can only manually adjust the lens position. The camera's image sensor is fixed in place.
The photographer knows that to get a sharp image, she must position the lens at exactly the right distance from the sensor. What distance d from the lens to the image sensor will produce a sharp image of the bird?
