Mamiya RZ67

The Mamiya RZ67 is a professional medium format single-lens reflex camera manufactured by Mamiya. There are three successive models: the RZ67 Professional (released in 1982), RZ67 Professional II (released in 1993) and RZ67 Professional IID (released in 2004). It is primarily designed for studio use, but can also be used in the field.

Details
The RZ67 is a modular camera system, meaning the lenses, viewfinders, ground glass, film winders and film backs designed for the system are all interchangeable. The RZ67's Sekor lenses have built-in electronic leaf shutters which are cocked and triggered from the body. Focusing is performed with a set of bellows.

The camera accepts 120 and 220 film film with film backs configurable for 6×7cm, 6×6cm and 6×4.5cm exposures. These backs are rotating, allowing for both landscape and portrait orientation without removing the back. Special-purpose backs allow for the use of Polaroid film as well as Quadra 72 4×5 sheet film. Mamiya RB67 backs are also supported via the G-Adapter. The film speed is set on each RZ back via a dial. There are two versions of the 6×7 and 6×4.5 backs. The model II versions have a second film counter to always show the film count on the top, regardless of the back orientation.

The RZ67 operates on one 6V 4SR44 silver oxide battery, or 6V 4LR44 alkaline battery. It can be used in an emergency with a mechanical mode fixed at 1/400 sec shutter speed. Multiple exposures are possible in the M-mode. Mirror lock up is supported for long exposures and macro photography. The body has one standard flash hot shoe on its left side, one plug for a standard shutter cable release, and a PC socket for an electronic shutter trigger. The RZ67 measures 104mm (W) × 133.5mm (H) × 211.5mm (L) with the 110mm lens, and weighs approximately 2.4kg (5.29lbs). The flange distance is 105mm.

The RZ67 name is adopted from the model name of the Mamiya RB67 (in which RB stands for "Revolving Back"), which was first introduced in 1970. The main difference between RB67 and RZ67 is that the RB67 is completely mechanical. The RZ67 body is able to transmit exposure information from the lens to the body. In addition, the RZ67 has plastic exterior body, making it somewhat lighter. Similar to the RB67, the RZ67 film backs 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). Both cameras also can manually set their shutter speed and aperture. In addition to manual operation, the RZ67 is able to operate in a automatic exposure mode with an AE viewfinder, which transmits exposure information directly to the body. In L compatibility mode, the RZ67 is able to use RB67 lenses.

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

RZ67 Professional II (RZ67 Pro II):
 * Some improvements of the electronics
 * An additional knob was added to the right side of the focusing unit for fine tuning of the focus

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


 * Four wide-angle lenses:
 * 43 mm . prototype lens. ULD glass, floating system and aspherical. 21 mm equivalent
 * 50 mm . Two versions exist, the non ULD and ULD L (contains floating element), the ULD version is clearly marked. 24 mm equivalent
 * 65 mm, two versions (the second one has a floating element), 32 mm equivalent
 * 75 mm, with floating element, 36 mm equivalent


 * Three normal lenses:
 * 90 mm, with extension tubes 1 and 2 has the largest magnification of all RZ67 lenses, able to shoot 1.92:1. A prototype lens of 90 3.5 M L-A with floating system also exists. 44 mm equivalent
 * 110 mm, smallest of the RZ lenses, also has largest aperture, 53 mm equivalent
 * 127 mm and an older model, 62 mm equivalent


 * Eight telephoto lenses:
 * 150 mm, 73 mm equivalent
 * 180 mm, three generations,W-N version is the latest and has improved optics, 87 mm equivalent
 * 210 mm APO, apochromatically corrected design, 102 mm equivalent
 * 250 mm, 2 versions (newer one is APO), 121 mm equivalent
 * 350 mm APO, 170 mm equivalent
 * 360 mm, an older lens, 175 mm equivalent
 * 500 mm APO and an older model, longest of the RZ lenses, 238 mm equivalent


 * Seven specialty lenses:
 * 37 mm Fisheye, (the widest RZ lens), captures 180 degrees diagonally across the frame, does not correct distortion, 18 mm equivalent
 * 75 mm 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 Shift, perspective control lens, needs manual cocking of the shutter, 36 mm equivalent
 * 140 mm Macro, two versions - "Mamiya M Macro L-A" and "Mamiya-Sekor Macro Z W" (both containing floating element system with "M" being the newer of the two, producing better results), able to shoot 1:3 without extension tubes or bellows and 1.22:1 with extension tubes 1 and 2, 68 mm equivalent
 * 180 mm Variable Soft Focus, uses three interchangeable diffusion and spherical aberration disks for soft effect, 87 mm equivalent
 * 180 mm Short Barrel, for tilt and shift adapter, needs an SB spacer for normal 180 mm use, 87 mm equivalent
 * 100-200 mm Zoom, the only RZ zoom lens, 48-97 mm equivalent


 * All RB67 lenses are mechanical only

All lenses have internal electronic Seiko #1 shutters with a maximum 1/400 sec speed, PC-type X flash sync plug, T-switch for long exposures, a plug for a standard cable release for B exposures, depth of field preview lever, distance scale, aperture adjust ring. In "B" mode, the RZ67 models will expose up to 30 seconds (a warning beep will sound for the last 10 seconds). In "T" mode, the camera can expose indefinitely without drawing power from the battery. Most lenses, except for the 37mm, 75mm shift lenses and the 500mm lenses have 77mm filter threads on the front of the lens. Those lenses have 105mm filter threads. Some lenses have a floating element; focusing these lenses involves setting a subject distance ring on the lens after focusing with the bellows.

Famous photos
Arguably the most famous photo taken with this camera is the "Bliss" photo used as the default background for Microsoft Windows XP. Seen by millions of people every day, this photo was taken by photographer Charles O'Rear in 1996.

RZ67 was used by Annie Leibovitz for many of her famous works in the 1980s and 1990s
