Exakta Twin TL
The Exakta Twin TL is a 35 mm SLR camera, made for Ihagee Kamerawerk AG ('Ihagee West') by Petri in 1970 (McKeown gives the date as about 1973), and later by Cosina. It makes 24x36 mm images on standard 135 film. It was only made in all-black finish.
The Twin TL has the same lens mount as the Real, a 46 mm bayonet, similar to the original Exakta bayonet, but larger, and accommodating an internal stop-down linkage. Adapters ('system rings') were available to allow lenses with the smaller Exakta mount, or a 42 mm thread mount, to be fitted. The Exakta Twin TL 42 is a similar camera, made with a fixed 42 mm thread mount.
The camera has a Copal focal-plane shutter with metal blinds travelling vertically, giving speeds 1 - 1/1000 second, plus 'B'. The shutter is synchronised for flash with X-synchronisation at 1/125 second, and M-synchronisation at all speeds. There is a hot shoe on top of the (fixed) pentaprism, and separate X and M PC sockets on the left-hand end of the top housing. There are two shutter release buttons; one in the conventional place on the top plate, convenient for the right index finger (this one is threaded for a cable release), and another in the traditional place for an Exakta, on the front of the left side of the top housing, more convenient for a left-handed user, and mating with the lens-mounted release button if an old Exakta-mount lens is fitted. There is a self-timer (delayed action) on the front of the camera, to the right of the lens.
The Twin TL is the first Exakta with a built-in meter, a CdS meter reading through the lens. This is used for stopped-down metering, with a match-needle display in the viewfinder. The meter requires a 1.3 V mercury battery, which is fitted under a cover in the base. The meter switch, which also stops down the aperture, is to the left of the lens mount. The film speed is set on a dial on the right side of the front of the camera. There is also a film-type reminder dial around the rewind crank.
The camera has lever film advance, and a folding crank for rewind. There is a frame counter, which resets automatically when the back is opened. The shutter is cocked automatically when the film is advanced. There is a prismatic focusing spot in the centre of the focusing screen.
