Fuji 670 quirks

[Keefe Borden]

I purchased a fuji GW 670 rangefinder recently and am gradually getting to know the camera. Its lens is sharp and clean, the shutter seems to work, and the exposures I get from it are accurate, but it has a couple of quirks that may be unique to this camera (meaning it needs servicing) or it may be universal features to all fuji range finders.

First, the film advance mechanism doesn't work the way my 35mm Nikon used to work. On the old Nikon, the film advance lever was wound once to advance exactly one frame and to cock the shutter. The Nikon's mechanism was ratcheted and if I accidentally did not wind the lever enough, the shutter would not fire. This feature prevented overlap of images on the film. The Fuji film advance lever doesn't work that way. It does wind and it is ratcheted in the same way, but one full wind does not advance the film enough. It leaves a small overlap on the negatives. To make sure I wind the film enough, swing the lever twice: one full twist and about a third of another twist. Once I learned to use the mechanism this way, the images on my negative were evenly spaced and I did get 10 of them on a roll of 120 film. My question: is this setup universal to all medium format range finders or is it just Fuji... or does my camera need servicing?

The second question revolves around the T setting, since there is no bulb. On my old Nikon rangefinder, T meant the shutter stays open after the button is pressed. It closed only after you twist the film speed dial to any setting other than T. (In my opinion, a completely useless setting given that there is a bulb setting right next to it. But I digress). The T setting on the Fuji Rangefinder opens and closes the shutter at some unknown speed after pressing the shutter release button once. There is no pressing the button once to open it and then again later to close it. My questions: is my T setting functioning properly? If so, what exactly is it used for? How can I do exposures longer than one second with this camera?

Thanks in advance for all feedback. Keefe.

My 690 the shutter doesn't cock until you fully advance the film. Yes it takes longer then one wind IIRC.

I don't use the T but I assume you need to hold the button down. Use a locking cable for long exposures. Or just a normal cable for more reasonable ones.

I believe all of the Fuji range finders need the extra bit of winding. My gsw690iii certainly did.

There is no bulb on any of the Fuji cameras.

If my GW670ii is any sort of example, you are correct, it requires you to advance the lever twice to get even frame spacing. Actually, you will notice that the 2nd push of the lever decreases in distance as you get further towards the last frame.

I haven't used the T setting yet, but assume that Nick is correct.

On the T setting, you fire the shutter by pressing the shutter release button as normal. The shutter should stay open until you turn the shutter speed dial. It's not the best system, but it does work. You can also close the shutter by slightly turning the film wind crank... not a good idea.
Any camera shake introduced by turning the shutter speed dial is a very small fraction of the total exposure time that it has virtually no effect on sharpness.
I have the GW670II and GSW690III and love using them. Great lenses.

I am grateful for all replies. I shot another roll while working with the T function. I waited between 15 and 30 seconds before twisting the shutter speed dial and I heard the faintest click when I did so. I have to assume that was the shutter closing, but I'll know for sure after I process the film tonight.

As mentioned, I noticed that the film advance lever requires less additional turns as I shot through the roll. My guess is that the take-up spool grows thicker as more film is wound around it, so each twist of the wrist takes up more film. That's a clever design that I would not have thought about.

As other photographers have reported, it is a neat camera with a sharp lens, accurate shutter, large viewfinder and clear rangefinder mechanism. I agree with that assessment. Despite that, I'm puzzled by some of its other design features. To start with, the hood is constantly in the way when you need to change shutter speed or aperture. It's too short to be of any real use as a screen for the sun, so I don't know why it's there. Secondly, the shutter is unusually loud. I have no idea why the mechanism sounds so hollow when the shutter clicks. There is no mirror inside flapping around, but it sounds like a spring is popping loose every time the shutter opens. Finally, it's just as easy to install a bulb setting as it is to install the T setting. For whatever reason, Fuji decided not to do so.

I haven't seen the exact specs on the new Fuji Rangefinder, but I won't buy one until these issues are addressed.

As for my own camera, it produces great negatives despite its quirks. Thanks again for all replies.

The hood should be pulled out so it doesn't cover the shutter speed dial/aperture dial combo. If it is covering them, it is not in the proper position.
As for the shutter sound, I have been told it is actually the counter mechanism on the bottom of the camera. This counter lets you know how many times the shutter has fired... 1 on the counter = 10 times it has been fired. You get used to the sound after a while.
I hope this helps.

Gene: Thank you for your feedback. After running through one more roll tonight, I discovered one additional quirk that I hadn't noticed before: the T mechanism only works with the shutter release knob on top of the camera. The one on the face of the camera left me with two large blank spaces where my images should have been on the film. After putting an exposed practice roll into the camera, I discovered that the two shutter release buttons don't behave the same way when you put the speed on T setting. The top button performs as you describe, but the shutter release button on the front of the camera opens and closes it at an unknown speed.

I'm not disappointed, however, as I consider all of this part of the learning process. The good news: exposure looks good on all other images on the neg, the images are evenly spaced, and there is only one minor sign of error on the rest of the negative.

All told, I'd say it was a reasonably productive evening.
Best regards, Keefe.

Good advice, Gene! I own 3 Fuji MF rangefinder cameras (GW 690 III, GSW 690III AND GW 670 III). Great cameras all!!

Time exposure: To make long-exposure pictures, set the shutter selector to “T” (Time) and press in the shutter release. The shutter will remain open even if you take your finger off the shutter release.

To close the shutter, just turn the shutter speed selector back towards “1.”

On a time exposure, it is also possible to close the shutter by operating the film advance lever, but if you do this, the film will be advanced a bit and thus the position of the film will be changed a bit during the exposure, causing some image effects (image smearing, distortion, etc.).


To close the shutter in order to terminate a time exposure, always turn the shutter speed selector. Do not operate the film advance lever.

Installing BULB capability in the Fuji's Copal shutter is a design complication that would increase the complexity of the shutter with little or no gain in functionality, IMHO. As has been mentioned before, there already is a fully functional TIME Exposure function.
