  • Magnifying “chimney” hood – better light sealing and high magnification than waist level finder. The chimney finders look directly down on the screen, they do not contain a pentaprism. Hence, they keep the left/right reversal of using the waist level finder.
  • Dual magnifying “chimney” hood – similar to the above but magnifies the center view between 3x and 5x.
  • CdS “chimney” – built in CdS meter with TTL metering. This is a bit strange of a meter, you actually move a little sensor around the view finder, giving you a spot meter. Note, this meter is not tied to the camera in any way, you have to move the settings read from the meter to the camera, there is no connection. This meter only features a on/off switch, so if you forget to turn it off, the batteries will drain.
  • CdS prism finder – A bit simpler than the chimney CdS meter. This is an averaging meter and it is a prism, so it corrects the left/right reversal. It only features an on/off switch, so the batteries can be drained.

Dual cable release

Due to the somewhat tricky nature of using a cable release on the RB67, Mamiya sold a dual cable release. It is a single plunger with two connectors, one is connected to the normal shutter release on the body, the other to the shutter release socket on the lens. As you press down on the plunger, the cable connected to the body triggers first triggering the mirror up, the cable connected to the shutter release on the lens is triggered, which activates the shutter.

    where can I buy the cable release?
    any recommendations?

    1. jodys Avatar

      I’ve never seen one under $50. Remember, though, that you can operate the camera in a mirror up mode with a normal single cable release. First, connect the cable release to the M-UP socket on the lens, select M-UP on the lens (if necessary), then press the normal shutter to lock the mirror up. Finally, use the cable release to trigger the shutter whenever you’d actually like to take the picture.

        It must not be the original cable. You can buy the double cable of any manufacturer. Pentacon ones are very comon and easy to find on the used market.
        Ofcourse you can help yourself with two separate cable releases, one in the camera body and the other in the lens. Just don’t forget to first press the one raising the mirror.

    Can you help me with what kind of battery works with the PD Prism Finder for the Pro S? You say it’s a photodiode cell, but maybe you can recommend a model?

    Thanks a lot, great website=)

    1. jodys Avatar

      You are welcome! I believe the specs call for “6V PX28 or equivalent”. Good luck!

      1. Valery Avatar

        You’re wrong. RB67 PD Prism finder uses 2 x 1,5V silver-oxide batteries. So it’s 3V together, not 6V

        1. Frank Gosebruch Avatar

          Sorry, no, YOU are wrong!
          The PD prism finder for Mamiya RB67 Pro SD:

          definitely uses a 6V battery – I use Kodak Lithium 28L.

            If you are talking about the CdS chimney finder the batteries are EVEREADY S-76. MALLORY
            MS-76E. RAY-O-VAC RS-76G or UCAR S-76 (Voltage: 1.5V) or any 1.5 V equivalent (1128MP, 1166A, AG13, D76A, G13A, GPA7, GPA76, LR44, LR1154, L1154, PX675A, PX76A, RPX675, S76, V13GA, RW82, KA, A76, 208-904, SB-F9, G13-A, CA18, CA19, LR44, GP76A, L1154H, A-76, AG14, AG-14, KA76, MS76H, CR44, LR44H, L1154G, LR44G, GPS76A, L1154C, L1154F, GPA75, GDA76, A613, LR44GD,SMC357)

            If you have the newer chimney finder that has the LED display instead of matched needles, or the PD metered prism, these take the Varta 6 volt V28 PXL Lithium or equivalent, eg:
            1x 6V silver oxide 4SR44, or
            1x 6V alkaline manganese 4LR44

    I am new to MF. Just wonder if the focus screen of RB67 offers 100% view ? Is this the case with other MF camera like Hasselblad 500 CM and Pentacon Six?

    tks alot 🙂

    1. jodys Avatar

      The RB67 has a design that is different than most SLRs (Hasselblad and Pentacon included). To change the orientation of the shot from landscape/portrait, the film back is rotated with relation to the camera body, rather than rotating the whole camera. The viewfinder shows something close to 7cmx7cm (bigger than the actual 56mmx70mm capture size) and has guides that move depending on whether you are shooting landscape or portrait to assist with framing. This means that the viewfinder will show a bit more than you will actually capture on film.

    I would appreciate it if anyone could comment on what screen and finder would be the best fit for low light/night photography? I can always shine a light on a portion of the frame and focus on that area, but are there any other advantages to a particular screen or finder that I am missing? I’ll probably always have the camera on a tripod, so weight or portability isn’t a problem.

    1. jodys Avatar

      I don’t have any direct experience with different screen, finder combos for low light photography. That said, I would guess that the waist level has the smallest impact on brightness. The original prism is noticeably darker and while I assume the the SD prism is better, I can’t say for sure. Please, report back with your findings so we can share it with others.

      1. Dave Avatar

        Thanks Jodys. This site is a great asset, I’ll definitely report back if I’m able to compare finders and/or view screens for low light photography.

          I would second Jody’s opinion, no matter which Prism Finder you find will be darker to view through compared to the WLF.
          Also if you are photographing night photography, I imagine that will be outside, therefore the weight factor comes to mind. You will be adding 700 + Grams to a already heavy outfit, that’s with the newer Prism Finder 2.
          Better have a good supper before heading out.

      2. Witold Avatar

        For low light I would suggest chimney finder as I find it much easier to focus. With dual magnification one (rather rare, but I think worth it) you get to see a lot closer and it helps focusing in low light.

        Others are saying prism finder makes viewing dimmer, but none seem to have actual experience using them. I don’t have one yet, but from the time I used one I did not think things were all that dimmer, maybe somewhat, but I have seen quite a few comments elsewhere people felt the opposite. Seems like one needs to see for himself to assess.

        1. jodys Avatar

          I have found that the prism has two downsiders: its weight (~2 lbs) and it _does_ make things dimmer. That said, it is not any worse than any other similar vintage prism. If you are fine with your SLR prism, you might be okay with the RB67 prism.

    Anyone have any experience with Grips for the RB?
    More recent Mamiya or earlier models which suit the RB & TLR- C330.
    or any aftermarket models such as Sunpak or Vivtar recommended?

    1. jodys Avatar

      I have used the basic left hand grip (I think it is common to the TLRs) and found the whole thing a) only useful when using a prism b) a bit unwieldy (though this might be remedied by going to the gym ;).

      1. Panoramic PEI Avatar
        Panoramic PEI

        Probably a tripod is a better bet,
        I am guessing with the combination of weight & size a bit unwieldy is starting to sound a little modest.

      I have the vari angle grip which although a little more expensive allows the grip to be angled back allowing for much more comfortable hand held shooting with a prism. It also has an off camera flash shoe. Much better than the silly sideways shoe fixed to the body.

    I receiving my RB67 Pro SD in few days. Wish to use radio triggered flashguns. Could someone give some info what radio triggers and flashes are good for this camera?

  9. Phillip Avatar

    I have 2 different radio flash trigger. I have not tried either one, but I might have time tomorrow morning, It is on my list to do.

    the newest set from Amazon:
    I don’t see why they would not work.

    As far as flashes, I mostly use old Sunpak 433D flash for canon or nikon. the 433D can be set to full down to 1/16 power. The flashes are relatively inexpensive and compatible with the ‘hotshoe’ radio receivers listed above. The receivers also have a PC Sync connector so are compatible with my 300 W strobes.


  10. Phillip Avatar

    Yes, the radio triggers work. When I have more time I will do a shutter range test. I have heard that the radio triggers can have a small delay, causing poor results at higher shutter speeds. The test will be worth a roll of film.

    I am interested in adding to my Father’s RB67 Professional. The standard waist level system works but as I age I believe the Prism View Finder would be very helpful. That one item is the Prism view finder with PD or CdS metering. Can you advise if they will fit the original body for the RB67 and if so which is seen as being more efficient. In what I have read I would say the PD would be the better choice but I would appreciate your opinion(s).

    Thanks for your help!

    1. jodys Avatar

      I’ve never found a working metered finder at a reasonable price. I suspect, but can’t confirm, that it would work with the original RB67 body. That said, if you intend to use the RB67 outside the studio, consider the substantial weight of the prism. You can, with practice, get used to using the waist level finder.

    Could anyone tell me what type of battery do you need for the Mamiya CDS Prism?, this prism is used with the Mamiya RB 67 Pro S only, thanks heaps.

  13. Witold Avatar

    The CDS chimney is NOT some sort of spot move around. As per Mamiya own instructions, it must be pivoted to center spot “only” for a reading. If a different spot needs to be measured, the camera is to be moved so its center spot sees the required area. I assume it must have something to do with how they calibrated it to their focusing screens. If there is a non-Mamiya screen, meter needs to be calibrated for the new screen (or a compensation factor determined for error correction).

  14. Frank Gosebruch Avatar

    Just two little corrections:

    1. The PD Prism Finder will not work on any RB67 camera when not using SD focusing screens.
    There is a small switch at the bottom of the finder.
    This switch enables the manual start of the metering system – just (!) with SD type screens.
    The older screens do not press the switch. So the PD Prism Finder should be in the SD section.

    2. For Pro SD I miss the focusing screen SV707 for to use the ZD back (or ZD back DB) with the adapter HX702.

  15. Johnny Avatar

    Does anyone on this feed own a “Dual Magnifying Hood 3x – 5x ” If so does the view cover the whole image or do you just get a telephoto view of the center where it’s magnified? Or does it give you the option to magnify and without moving your eye from the hood switch to frame up. Thanks really appreciate it !

    Hi all. I’m wondering if anyone has experience with either a regular chimney finder or even better, a dual magnification chimney finder. I’m specifically curious to know whether the viewer can see the whole of the ground glass comfortably for composing.

    1. jodys Avatar

      I only have the regular chimney finder and it only works up close, so you can’t see the whole frame.
