The Escaflex J (エスカフレックスJ型) is a Japanese 6×6 SLR made by Esca Kōgaku in the mid-1950s. It was continued as the Rolly Flex (ローリーフレックス) after the maker changed its name to Rolly Kōgaku.

The Escaflex J
Description
The Escaflex J is a leaf-shuttered 6×6 SLR. It has a prismatic body with a cubic mirror box protruding at the front. The film runs from left to right and is wound by a knob at the right end of the top plate (as seen by the photographer). There is another knob at the left, whose purpose is unknown. The back is hinged to the left and the film advance is probably controlled by a red window.
The nameplate is in front of the viewing hood and reads ESCAFLEX on a black background. The center part of the hood is retractable, giving place to a sportsfinder, and has an Esca logo. There is also a loupe hinged at the back of the hood. The mirror is moved upwards when the release button is tripped and only comes back when the shutter is wound again.
The fixed lens is a three-element Tri-Lausar 80mm f/3.5 by Tomioka, focused by turning the frontmost element. It is mounted in an NKS leaf-shutter giving B, 1–200 speeds.[1] There is a depth-of-field scale around the focusing ring, and the aperture scale is above the shutter housing. The release button is in front of the mirror box, towards the top, and is actuated by the photographer's right hand. There is a synch post on the opposite side, of the ASA bayonet or PC socket type.[2] A wheel or knob is visible to the right, below the lens; it is sometimes plain silver or has a black centre part, and its function is unknown.[3]
Documents and surviving examples
The Escaflex J was announced in Japanese magazines from April 1954; the first advertisements are dated November of the same year and they only run for a short time.[4] The December advertisement in Asahi Camera mentions a PC synch post and gives the price of ¥9,800, case included.[5] One source mentions the price of ¥12,500, perhaps by mistake.[6]
The production volume was certainly very low. One surviving example is pictured in Sugiyama;[7] another is pictured in Lewis and in this page of the JCII collection.[8] These two examples show minor differences in the synch post and in the front wheel.
