Clarissa
The Clarissa is a tropical strut-folding camera for 4.5x6 cm plates, made by Ernst Lorenz of Berlin in the 1920s. The camera is horizontally oriented. The body is wooden, usually without leather covering, and the bellows is of red or brown leather. Most fittings are brass, and most examples seen also have a brass front standard.[1][2] Examples are also seen with a wooden front plate; unlike the brass front, this allows sideways lens-shift.[3]
The camera has a focal-plane shutter with speeds 1/20 - 1/1000 second;[1] there is a plate on the top, giving the shutter settings (slit width and spring tension settings) to give each speed. McKeown lists the Clarissa with either a 75 mm f/3 Meyer Trioplan,[3][4] or an f/4.5 Helioplan;[1] examples have also been seen with a Steinheil Cassar,[2][5] or an Emil Busch Glaukar Anastigmat.[6] One example has been seen at auction with a 9cm f/2 Rudolph Plasmat, and with body leather;[7] the auctioneer's notes describe this as a copy of the Ermanox, and state that only three examples of it are known. Any of these lenses has helical focusing (in contrast to the superficially-similar Nettel and Deckrullo-Nettel cameras by Zeiss Ikon and its predecessors, which incorporate the focusing mechanism into the struts).
Most examples seen have a folding Galilean or Newton viewfinder on the top. One example shown at Westlicht also has a ground-glass screen.[5]
