RZ67

The Mamiya RZ67 (first model released in 1982) refers to three medium format single-lens reflex camera models, RZ67 Professional, RZ67 Professional II and RZ67 Professional IID manufactured by Mamiya. RZ67 is a modular camera system, meaning lenses, viewfinders, ground glasses, film winders and film backs are all interchangeable. It is primarily designed for studio use, but can also (though with reservations) be used in the field. The RZ67 Sekor lenses have built-in leaf shutters which are cocked and triggered from the body. Focusing is performed with a bellows on the body instead of lenses.

The camera accepts 6x7 and 645 120 and 220 film magazines and Polaroid and Quadra 72 4x5 sheet film backs, and operateson one 6V silver oxide 4SR44 battery, or 6V 4LR44 alkaline battery. It can be used in emergency mode fully mechanically with fixed 1/400 sec shutter speed. Multiple exposures are possible in the M-mode. Mirror flip up is supported. The body has one standard flash hot shoe on its left side, one plug for a standard remote shutter cable release, and a socket for electronic shutter trigger. RZ67 measures 104 mm (W) x 133,5 mm (H) x 211,5 mm (L) with the 110mm f/|2.8 lens, and weighs 2,4 kg. The flange distance is 105 mm.

The RZ67 name is adopted from the model name of RB67 (Revolving Back), thus also RZ67 takes backs which can be rotated 90 degrees to provide a horizontal or vertical composition. The orientation is shown in the viewfinder with black guides. The viewfinder also hosts LEDs informing of the state of the camera (flash ready, low battery, dark slide not removed, shutter not cocked). In addition to manual operation (photographer chooses aperture and shutter speed), RZ67 is able to operate in AEF mode with a measuring viewfinder, which transmits exposure information directly to the body, and in RBL compatibility mode, in which RZ67 is able to use RB67 lenses. The biggest difference between RB67 and RZ67 is, that RB67 is completely mechanical. The RZ67 has also mechanical couplings between the parts, but the shutter is electronic, and parts are able to transmit exposure information with electronic couplings. In addition, RZ67 has plastic exterior body, which makes it somewhat lighter.

Original RZ67 Professional (RZ67 Pro I):
* Electronic shutter 8 sec - 1/400 sec with 1EV steps

RZ67 Professional II (RZ67 Pro II):
* Some improvements on the electronics
* An additional knob was added to the bellows for fine tuning the focus
* Shutter can be adjusted in 0,5EV steps

RZ67 Professional IID (RZ67 Pro IID):
* Has an integrated interface for communicating with digital backs (the earlier versions need either an interface plate or external triggering wires)

Lenses

There are a wide variety of lenses available for the RZ67:

* 3 wide-angle lenses:: 37 mm f/|4.5 Fisheye, the widest RZ lens ever produced, 18 mm equivalent in 135-format: 50 mm f/|4.5 ULD L (2 versions, the older one is inferior in terms of contrast and resolution), the ULD version has an additional floating system focus ring, 24 mm equivalent: 65 mm f/|4, 32 mm equivalent
* 2 normal lenses:: 90 mm f/|3.5, optically inferior to the 110 mm, 44 mm equivalent: 110 mm f/|2.8, smallest of the RZ lenses, also has largest aperture, 53 mm equivalent
* 7 telephoto lenses:: 150 mm f/|3.5, 73 mm equivalent: 180 mm f/|4.5, 87 mm equivalent: 210 mm f/|4.5 APO, apochromatically corrected design, 102 mm equivalent: 250 mm f/|4.5, 2 versions, newer one is APO, 121 mm equivalent: 350 mm f/|5.6 APO, 167 mm equivalent: 500 mm f/|6 APO, longest of the RZ lenses, 238 mm equivalent
* 6 specialty lenses:: 75 mm f/|4.5 Short Barrel, possible to use with a tilt/shift adapter for perspective and focus plane control, needs an SB spacer for normal 75 mm use, 36 mm equivalent: 75 mm f/|4.5 Shift, perspective control lens, needs manual cocking of the shutter optically superior to the SB version, 36 mm equivalent: 140 mm f/|4.5 Macro, floating element system, able to shoot 1:3 without extension tubes or bellows and 1:1 with extension tubes 1 and 2, 68 mm equivalent: 180 mm f/|4 Variable Short Focus, uses interchangeable diffusion and spherical aberration disks for soft effect, 87 mm equivalent: 180 mm f/|4.5 Short Barrel,for tilt and shift adapter, needs an SB spacer for normal 180 mm use, 87 mm equivalent: 100-200 mm f/|5.2 Zoom, the only RZ zoom lens, 48-97 mm equivalent
* Most RB67 lenses

All lenses have internal shutters with max 1/400 sec speed, X flash sync plug, T-switch for long exposures, a plug for standard remote cable release for B exposures, depth of field preview lever, distance scale, aperture adjust ring.
