    Mamiya RZ67 Pro II (non-D) digital back options

    Hi all,

    I've got a Mamiya RZ67 Pro II (non-D) being delivered tomorrow, and whilst I am happy to develop I thought it would be interesting to investigate digital backs.

    I have read almost everything I can find on the internet about this, but it is still a little confusing.

    This question was recently asked, very similar:
    http://www.getdpi.com/forum/medium-f...67-pro-ii.html

    As far as I can conclude:

    ANY digital back less than (probably 3,000 is going to have poor low light performance (due to older CCD sensors)
    EVERY digital back is going to crop the flip out of my photos and I can forget the nice 6x7 size that I bought it for

    In addition, if I adapt my non-D Pro II for Mamiya digital backs, I lose the ability to load film, which I don't want.

    This was a useful resource:
    https://www.phaseone.com/en/Search/A...3&languageid=1

    Essentially I can use the Hassleblad V systems and avoid having to adapt the camera and sacrifice film.

    So, my questions!

    1 - Forgetting money and just in fantasy land, what is the best possible digital back I could buy today for my RZ67 Pro II?

    2 - And at the other end of the spectrum - forgetting entirely any consideration for quality - what is the cheapest possible digital back set-up I could get for my RZ67 Pro II that doesn't sacrifice the film capability?

    You don't sacrifice film capability. All you need is a specific adapter plate and one shot cable for the digital back.
    What you need to decide is how you are going to work around shooting film and digital, since you need to install a 645 mask in the viewfinder of RZ67 to compose for the digital, and remove it to compose for film.

    I personally really wanted P65+, but had to settle for IQ160. Both are near full size medium format (645). Going to P30/40/45 or IQ140 will crop your work even further, and with RZ lenses you can't go wider than 37mm.

    People here are surely more on the ball to answer the prices, so I hope you will be able to find some compromise.

    Regards

    Hi Krosavcheg,

    Thank you for your reply.

    From what I read if I use the Hasselblad adapter I don't lose film, but according to this Phase One page, specifically for the Pro II non-D:

    -Mamiya fitting-
    P/P+ series Mamiya fitting can also be used with the the Mamiya adapter (Item number 70994). Note:
    The Mamiya RZ PRO II needs to be modifyed in a local Mamiya center. The image below show 2 small notches that have to be made. If these notches are not made - the adapter can be mounted however the camera cannot trigger at all.
    I think I will have different sessions on different days, so one day digital and another dedicated to film; out of curiosity how difficult is it to install/remove the mask?

    The best I can find for the RZ67 is the Hasselblad CFV-50c, which still crops and has a 43.8 x 32.9mm, but it's 7,000

    Re: Mamiya RZ67 Pro II (non-D) digital back options

    Hi Josh,

    This thread contains some very useful information about which Mamiya adapter plate to use with your RZ67 ProII (non-D). It is the HX705.

    http://www.getdpi.com/forum/medium-f...524-df-rz.html

    There was a lot of confusion on that thread about which adapter plate to use and whether any modifications to a particular plate was needed for various reasons, so you'll have to sort thru it and see where things landed.

    The ProIID uses the HX701, which has the electronic communication to the back and camera built into the adapter, so a sync cable to the lens is not needed. I gave my RZ67 ProII to a friend and picked up a new ProIID and the HX701 adapter a couple of years ago, with the intent/hope of someday getting a digital back for it. I recently purchased a Phase One P30+ back from the GetDPI member PSon (thank you!) and in fact, it just arrived here at my office 30 minute ago, so I'm looking forward to trying it out soon.

    Unfortunately, there is just no way to get around a crop from the 6x7 film to a 6x4.5 (or smaller) digital sensor at this point in time. I certainly could not afford a "full frame" 645 sensor, but I wanted the next best thing which is a 36x48mm sensor (1.1x crop factor from FF645). I have seen Mamiya, Leaf and Phase One backs of this size in 22 and 33 megapixel varieties selling for $3,000 to $5,000 recently. You can get an older back in the smaller 33x44mm size (1.3x crop factor from FF645) for somewhat less.

    Although I still plan was to use the P25+ on the RZ67, I also decided to get a Mamiya 645 AFD II and a few AF lenses, just to have a camera which is slightly more portable and designed for the 645 format.

    Good luck finding all you need and an affordable digital back for your RZ! There are some excellent photos shot with the RZ and various digital backs posted in the "Fun with MF Images" and "fat pixel digital backs" threads here on GetDPI.

    Hi Gary,

    Thank you I'll definitely read through that thread!

    Thanks also for clarifying that right now there is no way to get the good old 6x7 in a digital sensor; it seems a shame, maybe we'll get there in a few more years I am particularly intrigued by the new Hasselblad X1D, but even that is still "only" 33x44mm.

    The P65+ looks interesting, too, with a sensor size of 53.9mm x 40.4mm, but it's $10,000 used at the only place I can find it right now

    Medium format is certainly an interesting if confusing world for cameras these days!

    I am also tempted to get a Mamiya 645 AFD II as it is more portable, I'm not sure I'll ever get rid of my RZ67 unless to upgrade to IID, because it's just such a beautiful, capable camera.

    Thanks again,
    Josh

    Josh

    I wouldn't think that making notches for the mounting of digital back adaptor would prevent the film back from mounting.
    One thing I can think of is that depending on how notches are made it may create light leak points that will obviously affect shooting with a film back. Though, any light leaks would equally affect the digital back, so it's somewhat unlikely.

    I recall seeing something in regard to this long time ago on the web. Best to check with a techie.

    Hi, thanks for the reply. I somehow missed it!

    I read on a Phase site that:

    "The Mamiya RZ PRO II needs to be modifyed in a local Mamiya center. The image below show 2 small notches that have to be made. If these notches are not made - the adapter can be mounted however the camera cannot trigger at all.
    Once this modification has been done - the camerabody cannot be used with a film cassette."

    I am not sure if this is 100% correct, but it worries me about putting Mamiya digital backs on it.

    I would trust the article on the matter.
    In this case, looks like the best option for you is to go with ProIID.

    Re: Mamiya RZ67 Pro II (non-D) digital back options

    K created an account just to help clear things up.

    First, there seems to be two versions of the HX701 adapter plate. One with a notch and one without. I'm guessing the one without the notch is an older version and that's the adapter that needs to be modified as shown by Sheldon N in this picture.




    And here's a picture of the two different versions. Pulled from the internet. I have the second version with the notch.




    As for Phase One's site saying it...

    "needs to be modified in a local Mamiya Center...Once this modification has been done - the camerabody cannot be used with a film cassette."

    I believe what they are meaning is maybe the physical removal of the dark slide pins, which would disrupt the film functionality.

    Sheldon N has shown instead, you can just simply dremel the adapter. This way it affects the body in no way and can still function with film backs without a problem.

    I think this confusion and blurb on Phase One's site is intentional by the way. Not gonna get into this now.

    Let me make this clear, YOU DO NOT LOOSE THE ABILITY TO USE FILM BACKS ON THE RZ WHEN GOING DIGITAL

    Now back to the adapter plates...

    There is the HX701 without and with a notch which I'll refer to as HX701v1 and HX701v2. And there is the HX705 adapter (It does exist, I have it). The HX701 adapters have contacts for use with the Pro IID. The HX701v2 can be used with the Pro II (non-D) WITHOUT modification but needs a sync cable. The HX701v1 can also be used with the Pro II (non-D) but needs to be modified as shown by Sheldon N, and also still require a sync cable. The HX705 should work with all RZ bodies with again a sync cable. Here's a picture of the HX705.



    As for the digital back mount type, the HX70x adapters are all for M-mount digital backs. So for the Pro II (non-D), you should consider getting a digital back (M-Mount) that DOESN'T need to be woken up, e.g. Leaf Aptus II or Phase One P65+, so all that would be needed is one sync cable.

    Now if you want to use a digital back that DOES need to be woken up, e.g. Phase One P25/P25+ or P45/P45+, then I think your best bet is using the Phase One adapter (item no. 70964) shown below. Remember this would need a digital back with a V-Mount. This option has both a wake cable and sync cable, so 2 cables.



    If you do not want the need for a sync and/or wake cable, then you'd go with a Pro IID body, HX701 adapter, and an M-Mount digital back (There seems to be a battery drain issue with this set up though).

    I have both the HX701v2 and HX705 adapter with a Leaf back and confirm its usage on the Pro II (non-D).

    Long post, I need a drink...

    Hope this finally clears things up.

    Cheers

The HX705 should work with all RZ bodies with again a sync cable. Here's a picture of the HX705 (Notice same notch).



    As for the digital back mount type, the HX70x adapters are all for M-mount digital backs. So for the Pro II (non-D), you should consider getting a digital back (M-Mount) that DOESN'T need to be woken up, e.g. Leaf Aptus II or Phase One P65+, so all that would be needed is one sync cable.

    Remember this would need a digital back with a V-Mount. This option uses both a wake cable and sync cable, so 2 cables. Also, this adapter doesn't allow for rotating the back. You must physically remove the back and re-mount the back in the orientation you want. Whereas the HX70x adapter plates still allow you to rotate the back (On a side note, before attaching the HX70x adapter plate to the body, you have to rotate the back first. So rotating with a digital back will now go counter-clockwise vs. clockwise with a film back).

    Leaf also has adapter plates, but I believe it can only be used with their Aptus backs. To use with say the Credo, I believe it has to be physically modified. This option also needs a sync cable.

    If you do not want the need for a sync and/or wake cable, then I'd say go with a Pro IID body, HX701 adapter, and an M-Mount digital back (There seems to be a battery drain issue with this though).

    I have both the HX701v2 and HX705 adapter with a Leaf back and confirm that it works on the Pro II (non-D) body.

    Long post, I need a drink...

    Hope this helped clears things up.

    Re: Mamiya RZ67 Pro II (non-D) digital back options

    Just one word to say: THANK YOU WARPATH

    I was looking for this answer for years, and i don't even know how you found it, cause, trust me, i've been searching, and dig the all internet.
    Now, i know i have a HX701 version 1.
    I knew for the HX705, but i suspected a "bizarrerie" with the 701, cause i already had in my hand one 701 that works, and an other one that don't, between a D and non D. I never understood why, now i know. And i should have kept the first one 701, i obtained for a real bargain haha
    But hey, that's obvious, 2 versions of the same model
