The maximum time that the shutter is open, allowing light to strike the image sensor. Slow shutter speeds are used for a variety of shots with special effects or with targeted out of focus images.

ISO specification indicates the camera sensor's sensitivity to light. Higher sensitivity is primarily used in low light conditions to avoid unwanted noise and blur.

Lenses for cameras vary based on several different factors, including type, construction, focal length, and maximum aperture. The two basic types of lenses are fixed focus (prime) and zoom. Fixed lenses have a single focal length and are generally considered to be able to provide sharper and clearer images than zoom lenses. Zoom lenses allow you to vary the focal length and thus adjust the level of zoom in or out.

The minimum focal length is the smallest distance at which the lens can be focused. This value is usually given in millimetres and is a determinant of how close to the subject the camera can focus. Cameras with a lower minimum focal length can focus on objects that are closer to the lens.
