Some may wonder why feet are such an important tool for photographers but they are. There are lenses that zoom to an extreme amount but there are cons with these lenses. If the farther distance the lens reaches, the less quality of the photo. These long distance lenses have a higher f/stop than a shorter lens. An important lens for a photographer is a 50 mm lens and it is the same distance as our eyes which isn’t far. Although it has a lower f/stop giving it that background blur that you may want to achieve. In some cases it does help to use a longer lens such as when you can’t reach your subject so you zoom. But in most cases we are able to move around and get a better shot.
