They are also well-known for having fast autofocus, which is key when trying to shoot wildlife or sports photography. In any case, the most negative aspect of a good part of current CSC systems is the lack of lenses. Disadvantages In most cases, single-lens reflex cameras cannot be made as small or as light as other camera designs such as rangefinder cameras, autofocus compact cameras and digital cameras with electronic viewfinders (EVF) owing to the mirror box and pentaprism/pentamirror. I've clarified my answer. Mamiya made versions that had interchangeable lenses. Did this satellite streak past the Hubble Space Telescope so close that it was out of focus?
