Which cameras take 118 x 118mm x 4mm lensboard-Mamiya RB67/RZ-lens adapter-

[europanorama]

My Mamiya RB67-lensboard/adapter 118 x 118 x 4mm can also take RZ-lenses when 2 pins are removed. I think its Graflex/Graphic dont remember.
Which cams have this lensboard-size? owner told trigger not that reliable regarding shaking. was on ebay for quite a long time. now rather rare. Thanks a lot

 

[europanorama]

have seen right now a sinar-version but not with shutter-release. pls explain. why here? cannot test with my RZ 180mm since tubes are seperated. another sad story but i can repair easily.

 

[Donald Qualls]

I can only confidently tell you what it doesn't fit: it's not for Anniversary or Pacemaker generation Speed Graphic, nor for Graphic View (either version). Those take 4x4 inch (= ~101 mm) boards. It does look very much as if the adapter flange could be installed on almost any lens board, however...

 

[abruzzi]

I have one (no RB lenses yet) but Donald is right, it should be easy to transplant on another board. It won’t be useful for 4x5, and even 6x9 may be tight, but my plan was to adapt it to a Cambo SC-1 lens board.

Now i remember: Its for chinese Liere 67. Multiple cameras, hard to find and nowhere to buy. its very strange how chinese cameraproducer and its wholeseller are behaving. think its enough to visit photokina. without announcing or showing products online. ktcamera also under different name doesnt exist anymore. he showed a genious dual-lens-shiftpancam(multiple versions for different lenses also custom lenses) for 120/220-59mm image but i didnt know before travelling so had no money to buy. website also gone. multiple liere cams. maybe google helps. i have found some.
also the tiny MUP-Graflok 23/RB67-cam cannot be seen anymore on ebay. asked a seller to recover link/seller which i sent him.
when he should have shown me camera and help shooting he had no time since had to go to fleemarket. and his assistent didnt know anything. thats why one shot is offfocus. the second one not perfect in focus.
have prospectus. of shenlong360. nothing to do with this adapter.

 

[Donald Qualls]

I think this adapter would be a nifty thing to have on a Century Graphic board. Same bellows draw for all the RB lenses, roughly what a 90 wants without optical trickery.

You say they don't sell it (or make it impossible to actually buy)?

Gone now... I'll have it in a bit. Thanks!

 

[abruzzi]

My idea behind getting one (still to be done) is I have a 6x9 monorail—Cambo SC-1– that has one annoying flaw…I have to jump through hoops to focus anything wider than a 75 at infinity. They probably won’t fully cover 6x9, but the RB lenses will obviously cover 6x7, and the minimum bellows on all of them is going to be the RB’s FFD of 112mm, so no problem at all.

 

[Donald Qualls]

I think the RB lenses will cover 6x9. They cover 8x8 readily enough (that's the focusing screen size on the ProS and ProSD bodies), and they fill out the entire frame mask on the old pack film Polaroid backs for RB67.

Does make me wish it were quicker/easier to recalibrate a Kalart rangefinder, though.

Hi Micheal
With Sinar they make mechanical and digital shutters that go just before the front bellows, and the back of the front standard. So any barrel lens can be utilized

We’ll see. I did get a Mamiya 50mm from their press cameras, and that definitely does, but even in a recessed board it requires flipping the rear standard, which, if you want landscape orientation, requires mounting the rail with the standards coming off the side. Doable, but annoying.

 

[Donald Qualls]

Aye, we will indeed see. I should have my adapter sometime in June (free shipping from Asia isn't fast), then I have to find time to change it to a board that will fit my Century, and find time to shoot and process a roll of 6x9. Hopefully before end of year...

 

[epatsellis]

Donald, the 50 and 65 don’t cover 4x5, 90, 127, 140, 150 soft focus, and 180 do. No additional shutter needed, set the lens to mirror up, rotate lever, lens will close and stop down, use shutter release cable socket on lens to trigger. This isn’t new, I built one ~’03 or so, the final result being this:

 

[Donald Qualls]

Nice. In my case, I'll need to make two adapters -- the mounting/triggering/cocking ring is bigger than the original lens board on my Century, so to use this on that camera will require making an adapter that sets the ring forward enough to clear the locking plates; the board it came on is smaller than the 4x4 I need for my Annie Speed and Graphic View II, so I'll need an adapter for that as well. It does correctly trigger the shutters in the lenses, though.

 

[Neil Poulsen]

I have one of these, though I've not yet mounted it to a lens board. It works fine. I made sure to purchase one before the supply ran out.

And that's my plan, to mount it inside the deep recess of an Arca Swiss recessed 171mm lensboard. It's easy enough to pick a camera with a lensboard at least the size of the Mamiya lens adapter, cut a hole of the appropriate size in that lensboard, and then, mount the Mamiya adapter to the larger lensboard using a bolt and nut at each corner. (Size 6 nut and bolt?)

I figure that the lens will balance better with the adapter mounted inside a recessed lensboard. In that way, the rear of the lens will extend at least some distance behind the standard to offset the lens weight at the front.

If I recall, after cocking the RB67 shutter using the lever, one can trigger the shutter using a shutter release cable. One has to get the settings just right on the lens for this to occur.

What's amazing, is that some of the longer RB67 lenses will cover 4x5! Somewhere on the Mamiya website, one can find image circles for RB67 lenses. That said, I will probably use this with a digital back.

 

[Donald Qualls]

If I recall, after cocking the RB67 shutter using the lever, one can trigger the shutter using a shutter release cable. One has to get the settings just right on the lens for this to occur.

With this adapter, you'd set the selector on the lens shutter to M (for Mirror Up), cock the lens to open the shutter for framing/focusing, then move the lever back to prefire (closes the shutter, which on the RB67 would go with firing the mirror); at that point, you can fire the shutter with a cable release in the center of the selector.

I'm disappointed to realize I probably can't use this on my Annie Speed with the LomoGraflok; that adapter puts the sensitive area near a corner of the 4x5 frame, and the required front standard setback subtracted from the nominal 112 mm flange distance for RB67 lenses would make it almost impossible to set the infinity stops. The mechanical part of the adapter is larger than the standard opening in my Century Graphic, but I believe I can 3D print an adapter to space the mount forward to clear the locking slides and be able to use this on that camera -- giving quick, easy access to lenses from 50 mm (22.5 mm with 0.45x filter) to 250 mm on all of my 2x3 Graflok mountable film backs, on a camera substantially lighter than my RB67.

 

[M Carter]

you'd set the selector on the lens shutter to M (for Mirror Up),

A minor note - some RB lenses require a cable release to be inserted for mirror-up, there's no switch. Screwing the release in lifts the release port up, which disables the trigger from the camera to pop the shutter (if you've never seen that style and then buy an RB lens with it, it can be a surprise).

 

[Donald Qualls]

@M Carter Useful note. None of my Sekor C lenses work that way, but I can see that being done on the late units or RZ lenses to simplify operation.

Funny, I think every iteration of the zoom is like that, as far as the ones I've seen. (I keep almost buying one...)

 

[Donald Qualls]

Odd. Were the zooms not made by Mamiya, or the shutters something other than the Seiko found in most/all of the primes?

 

[MattKing]

The later versions of the lenses implemented that approach.
I think the zooms are all relatively recent.

skgrimes had it converted to arca-swiss.

skgrimes did an arca-conversion. seller photopro told lever would move too much.
