What is the equivalent angle of view for a 200mm lens on a cropped sensor camera with a multiplication factor of 1.6?

1. 160mm

2. 200mm

3. 320mm

4. 400mm

The correct answer is: 320mm

To determine the equivalent angle of view for a 200mm lens on a cropped sensor camera with a multiplication factor of 1.6, you simply multiply the focal length of the lens by the crop factor. In this scenario, you would take the 200mm focal length and multiply it by the crop factor of 1.6. This calculation is as follows: 200mm * 1.6 = 320mm The result of this multiplication indicates that a 200mm lens on a camera with a 1.6x crop factor provides a field of view equivalent to a 320mm lens on a full-frame camera. This is important for photographers to understand because it affects composition and framing when switching between different sensor sizes. Understanding this concept helps photographers choose the right lens for their desired image capture, matching the perspective they want to achieve.
