The simplest cameras have fixed focus and use a small aperture and wide-angle lens to ensure that everything within a certain range of distance from the lens, usually around 3 metres (10 ft) to infinity, is in reasonable focus. Fixed focus cameras are usually inexpensive types, such as single-use cameras.For wide-angle lenses, allowing lens designers to make lenses whose rear elements can come very close to the image plane lets wide-angle rangefinder lenses be much smaller, sharper and have less distortion than SLR lenses.
