Camera Lens Characteristics All lenses filter and focus light so 1. it hits the sensor or film strip correctly. However, there are a variety of other factors that determine 2. a camera lens affects the look and quality of the final photo. •Focal length is the measurement of distance (in millimetres) 3. the point of convergence of your lens and the sensor recording the image. The focal length range of a lens is expressed by a number, and that number tells you how much of the scene your camera will be able 4. capture. Smaller numbers have a wider angle of view and show more of the scene; larger numbers have a narrower angle of view and show less. •Aperture is how big the opening is that lets light in, expressed in f-stops. F-stops 5. counterintuitive, because the larger the number, the smaller 6. opening. For example, f/2.8 allows twice as much light into the camera as f4, and 16 times as much light 7. f11. Aperture affects the depth of field: larger openings create a shallower depth of field, while smaller openings make more of the image in focus. •Maximum aperture. Lenses will list a maximum aperture on the barrel, indicating the maximum width a lens aperture can open. Typically, lenses 8. a wider maximum aperture cost a bit more. A lens with a wide maximum aperture is great for low light situations, so if you are considering night photography, it might be worth the investment. •Depth of field. Controlling the amount of the photo 9. is in focus is one of the photographer’s best tools to help draw the viewer’s eye to where you want. It varies with the type of lens, due 10. maximum aperture. Lenses with longer focal length tend to have a shallower depth of field, meaning you can focus on and separate (or isolate) a particular object far away, whereas shorter lenses have a deeper depth of field, which means you can get more objects in focus throughout the image.
