Epsilon shutters are rim-set leaf shutters made by Barnet Ensign Ross (and the same company under later names) for their own folding cameras, in the late 1940s and 1950s. The same name, usually appearing on the face-plate, below the lens, was used for shutters with at least two levels of specification. The shutters have a cable-release socket, but no delayed action. They are synchronised for flash, with a PC socket. Epsilon shutters also appear on some examples of other British makers' cameras (such as the Kershaw Curlew).
