24mm
Common socket size
24mm refers to a focal length for camera lenses, indicating 24 millimeters between the optical center and the image sensor.
This wide-angle measurement captures broad scenes with minimal distortion, making it popular for landscape photography, architecture, and street photography: I shot the whole cityscape with my 24mm.
The term functions as shorthand for any lens of this focal length.
