Mode dial

A mode dial or camera dial is a dial used on digital cameras to change the camera's mode. Most digital cameras, including dSLR and mirrorless cameras, support modes, selectable either by a rotary dial or from a menu. On point-and-shoot cameras which support modes a range of scene types is offered. On dSLR and mirrorless cameras, mode dials usually offer access to manual settings. The more compact point-and-shoot cameras, and cameras offering a great many modes, do not have mode dials, using menus instead. Some interchangeable lenses themselves offer control over things such as aperture, reducing the need for mode support in the camera body.
