An 108 millimeter focal length lens is used to focus an image on the sensor of a camera. The maximum distance allowed between the lens and the sensor plane is 134 millimeter.
A) Find how far in front of the sensor should the lens (assumed thin) be if the object to be photographed is10 meter away from the lens?
B) Find how far in front of the sensor should the lens (assumed thin) be if the object to be photographed is3.0 m away from the lens?
C) Find how far in front of the sensor should the lens (assumed thin) be if the object to be photographed is1.0 meter away from the lens?
D) Find the closest object this lens could photograph sharply?
