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
• Shutter can be adjusted in 0.5 EV 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)
• Minor internal mechanical improvements

• 
  RZ67 Pro I
• 
  RZ67 Pro II, not much exterior difference between the models except the Pro II version has a critical focus knob.

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

• Four Wide-angle lenses:

43 mm f/4.5. prototype lens. ULD glass, floating system and aspherical. 21 mm equivalent

50 mm f/4.5. Two versions exist, the non ULD and ULD L (contains floating element), the ULD version is clearly marked. 24 mm equivalent

65 mm f/4, two versions (the second one has a floating element), 32 mm equivalent

75 mm f/3.5, with floating element, 36 mm equivalent

• Three Normal lenses:

90 mm f/3.5, 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 f/2.8, smallest of the RZ lenses, also has largest aperture, 53 mm equivalent

127 mm f/3.5 and an older model f/3.8, 62 mm equivalent

• Eight Telephoto lenses:

150 mm f/3.5, 73 mm equivalent

180 mm f/4.5, three generations,W-N version is the latest and has improved optics, 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, 170 mm equivalent

360 mm f/6.0, an older lens, 175 mm equivalent

500 mm f/6 APO and an older model f/8, longest of the RZ lenses, 238 mm equivalent

• Seven Specialty lenses:

37 mm f/4.5 Fisheye, (the widest RZ lens), captures 180 degrees diagonally across the frame, does not correct distortion, 18 mm equivalent

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, 36 mm equivalent

140 mm f/4.5 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 f/4 Variable Soft Focus, uses three 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 which 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 standard remote 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 37 mm, 75 mm shift lenses and the 500 mm lenses have 77 mm filter threads on the front of the lens. The 75 mm shift lenses and the 500 mm lenses have 105 mm 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.

Polaroid also made a radio transmitter and receiver for the RZ series.

Arguably the most famous photo taken with this camera is the "Bliss" photo used as the default background for Microsoft Windows XP. Seen by many millions of people every day, this photo was taken by photographer Charles O'Rear in 1996.[1]
