Pro S and Pro SD Backs Double Exposure Lever

[film_man]

My 67 65mm and 90mm both have rotating depth of field scales, non floating blads lenses don't? A
specific and seductive problem. There is no indication that the 65 has a floating group and some don't (supposedly) my manual does not clarify latter case. My 65 lens group moves so I know it is floating...

Is your degree in sophistry?
-sophists always put a false phrase at front to permit their false hood argument. Politicians do this too.
I've used mine P&S 55mm preset to /5.6 and 6 foot. Lots of early 20th century press and candid shots were medium format or larger, indeed back then 120 was regarded as a minature camera film by some.

I would expect that it is the lens manual that describes how it works, not the camera manual.

With regards to your nasty question, no I do not have a degree in sophistry and I am not a politician.

On the other hand you seem to be one as you put words in my mouth. I never said that it was stupid to download the manual, you said it. You also claimed that the camera is difficult to operate yet when asked specifically you move the subject from the back to the lens, then the tubes, etc. You also said it is easy to take photos on the backing paper yet never explained how this can be done. It is all there for everyone to read.

Anyway, I do not find the RB67 complicated to use, certainly no more complicated than a Hasselblad or other medium format cameras. On the other hand you present yourself as someone who is seriously challenged by it. Fair enough but you shouldn't hold it against me that I can see the obvious.

So let's just leave it at that and a good day to you sir.

Reading the manual is always recommended, but I find the RB67 logical and simple to operate. The interlocks are very helpful I think. I also use a Mamiya Universal which has no interlocks whatsoever. That makes the camera simpler to use, in a manner of speaking, but I would have avoided a lot of blank frames and double exposures if the camera had something preventing me from making them..

That is an important point Trond.

Those new to the RB need to remember that the RB can do things that other cameras just can't or make it hard to do.

Try and switch films mid-roll in a Nikon or Canon or ... without rewinding or ruining the film and getting it back in exactly the right place to shoot the next frame, and then switch back to the other or to a third type of film for the next shot and without moving the camera.

Try turning the film 90 on most other cameras without messing with the tripod.

Try adjusting shutter speed and aperture to change DOF while keeping the exposure value constant, in one motion with just 2 fingers on another camera. (Yes I'm sure some others do but not that many)

I think I would agree with Matt. It's not a difficult camera to operate, it's just difficult to remember all the steps to take a photo. I can't tell you how many times I've tried to press the shutter, and nothing. And I check the shutter cocking, yup. Then I check the film advance, yup. Then I stare at it. For a while. And I stare some more. And then I finally remember the dark slide. I just can't get used to that darn thing! I also have a bad habit of forgetting to unlock the shutter....

But yeah, it's easy..........

The secret to using the dark slide is to leave it in your camera bag, with the intention that you only use it when you need it.

Although it does make an effective shutter release lock!

It was an inquiring question, just like your statement or question about my RB67 kit earlier.

I did not say it was stupid to down load the manuals I said you said it was stupid to down load the manuals. That is how I read the meaning in your text.

And I do use the RB as a P&S, so your phrase was false.

The camera came with two manuals a camera and a generic lens manual.

There were specific manuals for the 140 and 150mm, but Ive nor seen either.

The use for the 55 and 65mm may be described in specific lens manuals but I got (both of) my lenses new in box from shop and there was not a manual for either. The shop may have been wayward, but in the down load versions of the camera manual.

The MamiyaLeaf ProS PDF (for the camera)

page 23 has the old focus scale without the 140mm lens scale, my camera has the new focus scale, its serial c176xxx, the new scale came with some 140mm lenses, but would/could have been fitted new to late cameras, or on factory repair.

Page 24 implies that the 127mm lens has a depth of field scale like my 90mm has.

Page 25 caveats aperture used for close focus with the 55 and 65mm lens.

Page 26 notes 6 and 7 caveats use of 55 and 65mm lenses and tube 1.

(the Butkus site has a generic lens manual)

My lens manual seemed different in that it referenced specific lens manuals for the 150mm and 140mm but '85 is a while ago.

(note this is an earlier manual then mine from before the 65mm had a floating element, and both my 90 and 65 have a different profile.)

The answer to your last point is it is easy to miss thread 120 film if it is too dark to see the threading arrows, I now carry a flashlight in my RB gbag the same way I carry a screwdriver in the blad gbag. When you get home and into dark room when you find the film is not wound inside the paper (like normal) but outside the paper you know you have made a mistake, donno what I did.

It is even easy to take photos on the backing paper rather than on the film.

So has anyone used one without the manual?

This is true. I've luckily avoided this, but there are a number of threads and people who have loaded the film backwards. It's easy to do.
