Mamiya RB/RZ mix and match?

David H. Bebbington · Oct 19, 2007

I intend in the medium term to buy a second Mamiya body and thought this might as well be an RZ, provided that I can use most of the RB67 Pro SD components I own (3 KL lenses, 1 C lens, 3 Pro SD magazines, 2 Pro SD tubes). I understand the lenses will fit, research seems to indicate the magazines will fit too via a G adapter (supposed to be hard to find, but I got one on e-bay), and the Prism Finder 2 should be OK too (not sure about the WLF). Does anyone have experience of using components combined like this, do they work OK, are there any problems? Would appreciate any info.

Regards,

David

Are you sure about the finders? I thought they might short out the RZ? Odds are most RZ bodies come with a waist level finder anyways.

The lenses you'll have to set the RZ body shutter control to RBL [something like that] and set the shutter speed on the lens.

You'll of course lose any of the RZ additions.

Nick, I have the Prism Finder II (non-metered). According to the Robert White website, the "Mamiya RZ PD Meter Prism" also fits both RB and RZ (I think this gives a read-out in the prism which you then transfer manually to the shuter and aperture). There is also a "Mamiya RZ AE Prism II" which I suspect is the later model and offers AE operation - this is not stated to fit the RB, indeed I wouldn't expect it to.

Regards,

David

Those are issues with the RZ pro II, not the regular RZ pro. Some RZ finders won't even work on the pro II. The non-pro II RZ doesn't have a RBL setting on the shutter speed dial. It doesn't matter what the shutter speed dial is set to when you use RB lenses (on the non-pro II).

There are 2 different PD prism finders, one for the RB, and one for the RZ. The one for the RZ gets the aperture and shutter speed info from the camera body, and I'm pretty sure it can't be used on an RB. The one for the RB can be used on a non-pro II RZ (as with any RB finder). Neither of the PD prisms can be used on the Pro II. Most RZ finders (except for the prism finder 2) won't mount on an RB body (the prism finder 2 is the only finder I know of that can be used on the RB, RZ, and RZ pro II).

If the PD finder for the RB has an activation button on the bottom like the RB CDS prism, it will probably need a piece of cardboard or some kind of spacer under it to make it work on the RZ (that's the case with the CDS prism), because on the RZ (non-pro II), the button barely touches bottom when the finder is mounted (it doesn't push in far enough to close the contact).

Thought I'd dig up this old thread rather than post my own.

I'm curious as to whether the old RB non-metering chimney magnifying finder for sale in the APUG classifieds right now will fit my RZ Pro.

There should be no problems, but just wanted to double check with all y'all experts.

As you say, there should be no problems. Since the RB finders had no electrical interface, they pretty much operated independently and thus would work on any body they fit on. If I recall correctly, there was a chimney finder made specifically for the RZ that had all those fancy features like auto exposure and such.

Exactly why I want the older one. Cheaper, smaller, lighter, and has nothing on it that I will not use. I am also not sure if the later ones give you two magnifications, like the older ones do. I've never seen one in person and it is hard to tell from pix. The flip-up 6x check of the center dot on the screen is a great feature that I use for practically every shot I take on a tripod with my C series cameras.

My other ongoing search is for a non-metered prism for my M645 that does not have the all-too-common mirror separation line of doom.

Thanks for your reply.

I have the AE Chimney Finder for the RZ Pro and it has a variable dioptric adjustment of +0.4 to -1.8 which is very useful. I have it permanently mounted on one of my RZs that is used principally for macro work. Metering is bang on. It's even bright enough for easy focusing when using the 140mm macro with both extension units.

Hi to all!
I'm wondering if I can use RZ67 PD prism with my RB67 Pro SD? Tell me if the mount is suitable, I read somewhere that it is the same on both cameras.
Thanks!

Welcome to Photrio.
I always refer to the Reznitsky Table when issues of RB/RZ compatibility arise: http://www.reznitsky.info/Mamiya/Comchart.htm

Alan Edward Klein · Jun 10, 2021

I got this list somewhere.

MattKing · Jun 10, 2021

Alan:
That is the Reznitsky list I linked to .

Matt: I tried opening your link. But I got a virus warning so I didn't want to take a chance.

Not with my virus security system. It is a so called "not secure" site, but it is just a page without any links.

Some sites are marked "Not secure" by some anti-virus programs because they contain links which might be problematic.
Some sites - particularly lots of the older, not very active sites - are marked "not secure" by some anti-virus because they don't implement any of the more modern security provisions, even if those provisions are essentially unnecessary, because the page is essentially a graphic, with nothing non-graphical embedded in it.
If you encounter a webpage without any embedded links that was created a long time ago, is a static graphic, and hasn't been updated, it really doesn't present a risk.
Here on APUG/Photrio I've linked to the Resnitsky table many times over the years. You are the first to indicate any such warning. As I said, my quite robust internet security has no problem with it.

I got this from a demo malware program I'm trying from Malwarebytes. It says it's a Trojan.

pentaxuser · Jun 10, 2021

No issue with Kaspersky Internet Security and usually it is pretty good at identifying sites that look OK with for instance just a chart but which nevertheless has dangers in it. It may be that Malwarebytes has got it wrong

On another aspect I noted two names which I recall from my earlier days, namely David Bebbington, the thread's OP and another stalwart from the first decade, Nick Zentenna. Neither has been seen since 2008/9 I wonder what happened to both members?

Alan Edward Klein · Jun 10, 2021

I'm running Kaspersky like you as well. I don't think I'm going to get Malwarebytes although you sometimes wonder if more is better.

pentaxuser · Jun 10, 2021

So that's two of us, Alan, running Vlad's security. I hope that Sal doesn't notice

That's funny, because it looks like the chart is simple HTML and nothing more.

I figure that being Russian, who better would know how to stop malware, viruses, etc?

Thanks. From this table I see that the prism is not compatible with my camera. But is it about the work of electronics, or the type of mounting? I read somewhere that the type of mounting is the same on RB67 and RZ67.
