The 50mm f/4 Zeiss Distagon "EL" lens is part of a low-priced catagory of Rollei lenses for newcomers to medium format photography. "EL" lenses are modestly priced lenses for the novice, convert or young professional. They have a standard 67mm filter thread instead of a Rollei bayonet, external bayonet mount for lens hood, yet have an optical system identical to PQ lenses.
Rollei lenses for the 6000 series cameras are currently available in two versions - PQ and PQS. PQ lenses work with all SLX and 6000 series cameras an offer a top shutter speed of 1/500sec. PQS lenses are intended ONLY for the 6001, 6003 and 6008 cameras and offer a top speed of 1/1000sec.
