Photographing building interiors often requires a tripod, but improved high ISO performance and image stabilization enable photographers to shoot when tripods are not permitted. With Auto ISO selected, camera programming aims to ensure that shots are shake-free. Using the conventional photography rules of thumb, the camera attempts to keep the shutter speed to at least the reciprocal of the focal length. So, for a 50mm lens, this means a 1/50 sec shutter speed with Program or Aperture Priority modes. However several EOS R-series cameras have in-body stabilization that enables slower speeds to be employed, yet achieve successful images as long as the subject is still. If a lens has image stabilization, slower shutter speeds can also be used.
