How does increased focal length typically affect a camera's view?

• A. Increases the field of view
• B. Decreases the field of view
• C. No effect on the field of view
• D. Turns the camera into a thermal camera

Answer: (B)

Increased focal length has a significant impact on a camera's view by decreasing the field of view. A longer focal length allows for greater magnification of the subject being captured, making the object appear larger in the frame. However, this comes at the cost of narrowing the overall field of view, which is the extent of the observable area through the camera lens. In practical terms, as the focal length increases, the camera captures a smaller area, focusing on a specific subject while excluding more of the surrounding context. This principle is crucial for applications such as surveillance, photography, or videography, where the choice of focal length can determine the composition and detail of the scene being recorded.
