They use curved mirrors to 'fold' the light path inside the lens barrel, making the physical tube much shorter than the effective focal length would suggest.
It describes an optical system that uses both refraction (through glass elements) and reflection (off mirrors). 'Mirror lens' is the common term for a catadioptric photographic lens.
Generally not, due to their fixed aperture, manual focus commonality, and distinctive bokeh. They are niche tools best suited for specific subjects like distant wildlife or the moon.
