Mamiya TLR System Summary Photo Pages

*Miscellaneous Mamiya TLR Features*
This is the 105mm DS viewig lens from above. The scale at the bottom is part of the diaphragm for depth of field preview, and is currently set to f16. The next set of numbers is a conventional fixed depth of field scale. At the top is the distance scale on the rotating front of the lens that is used as a depth of field scale. This scale is not tied to the camera focus, and the viewing lens does not focus. This is just a calculator.
	The 105mm DS lens showing the flash synchonisation settings (X for instantaneous, M for flashbulb delay), and the V setting for the self-timer. The shutter lever position shows that the lens is uncocked and in contact with the shutter cocking arm on the C330 body.
This is the meter needle (moved in response to light intensity) and the ring of the matching arm (moved by adjusting the exposure meter dial) on the metered chimney finder. The metered Porrofinder uses a similar mechanism.
	C330s body left side showing the simpler lock / unlock control and parallax / exposure compensation control. It lacks the film reminder option, which is done using a film box top holder on the back. The short focal length focus scale is below. The tip of the moving shutter is yellow.
This is the right side of a C330s showing the Single / Multi exposure control coaxial with the winder. The shutter lock is to the lower right.
	This is the last variant of the single sheet backs produced for the Mamiya TLRs. It fits the C330 and the C330f, but not the C330s or the C33. This example was 'new in box', but the foam used in the seals had suffered and turned to sticky tar at first touch. It will have to be replaced. The felt light trap is fine.
Inside of the sheet film holder camera back. The C330-style back hinge pins are visible on the right, and the chrome catches on the left. Note the large circular opening which exposes the camera interior when a film holder is not present.
	Film holder. Holders are made with numbers from 1 to 3. When the catch is folder over the number the back shows 'E' for exposed.
Inside of the back with a film holder in place and the darkslide partially withdrawn.
	The film holder is designed to hold glass plates (practically unobtainable these days), or sheet film. The sheet film is held in a sheath that takes the place of a glass plate. This is the Type J sheath for 2 3/8 x 3 1/4 inch film. The Type D sheath does not have the slot and film guide inset on the right side - it is the full length of the sheath. The Type D takes 2 1/2 x 3 1/2 inch or 6.5 x 9 cm film.
Side view of the holder with the pressure spring catch released. This is normally done on the camera to press the film against the camera film plane.
	The back catch is slightly obscured by the film holder housing and is not easy to release. The back is stiffer than the standard back and appears less prone to uneven latching.
The back open, and this the holder retaining wire released.
	The holder installed in the back, and the retaining wire clipped in place. Note the two holes on the holder back towards the right of the picture. These mate with two matching pins on the outer back. Older film holders do not have this feature and will not fit this back.
The back closed with a holder in place. The pressure place catch and the holder identity number can be accessed through the central hole.
	The back, with holder, fitted to a C330. Note the amount of projection below the base of the camera which will influence tripod selection.
