31. This is because angle of view is a function of both focal length and the sensor or film size used. 32. Balconies, supported on wooden posts, housed additional instruments slightly further from the building, giving them a wider angle of view . 33. Most zoom lens hoods are designed for only the widest angle of view , offering progressively inadequate shade at longer focal lengths. 34. This series has a 120?angle of view , but the extremely short focal lengths only cover mostly medium format image sizes. 35. Conversely, a longer focal length ( telephoto ) lens captures a narrower angle of view , demanding a more distant viewer position. 36. When a larger angle of view is required, the standard method of projecting rays onto a flat picture plane becomes impractical. 37. Changing the focal length only while keeping the same camera position doesn't affect perspective but the camera angle of view only. 38. *Many existing images used in aircraft articles have been carefully selected to illustrate specific variants, angles of view or aircraft features. 39. Lenses are not labeled or sold according to their angle of view , but rather by their focal length, usually expressed in millimeters. 40. As a result of the different angle of view of each lens, the photographer moved closer to the object with each photo.
