A common zoom lens for a digital camera covers a focal length range of 18 mm to 200 mm. For the purposes of this problem, treat the lens as a thin lens. If the lens is zoomed out to 200 mm and is focused on a petroglyph that is 15.0 m away and 38 cm wide, (a) how far is the lens from the photosensor array of the camera and (b) how wide is the image of the petroglyph on the sensors? (c) If the closest that the lens can get to the sensors at its 18 mm focal length is 5.2 cm, what is the closest object it can focus on at that focal length

Ans:

Expert Solution

The answers are

(a)The distance of the photosensors form the lens is 20.27cm

(b) Width of the image = 5.135mm

(c) Closest object that can be focused has the object distance = 2.753 cm

A camera lens has a focal length of 100 mm (thick lens). The photographer first adjusts the location of the lens to look at an object very far away (infinite distance). Then he tries to take a picture of a person 2 meters away from the lens. How is he going to adjust (move) the lens relative to its original position? What is the distance of the adjustment?
