    Re: GX 680III Update

    Today I broke out a simple shutter speed tester and I have to say, the electronic shutter does one helluva job. I only have the 100mm f/4 at this point but it's looking to be crazy accurate. It's like one pleasant surprise after another with this thing.

    While I'm at it, the Tenergy CR123A rechargeables I'm using are doing great. I started testing how long they'd last (room temperature) and I ran out of juice while they still show full charge. Not exactly scientific but one more concern abated.

    I did work up a nice 16' 9 volt DC adapter that works a charm as well. I used a 1100mA power supply and it seems adequate. Still needs batteries in the film back to retain it's setting and fire as well. No batteries in the body works fine with the external DC supply.

    Hey, that should work. The outer flange is 6mm and the inner stem is 3.5mm. The 'B' strap should work. I just order it from Amazon.

    Thank You 4season.

    That looks very promising. Please report back when you've tried it.

    Re: GX 680III Update

    Yes, please let us know Gary if it's a go with that strap. I am rather lifted by the beautiful engineering of the Fuji strap but something has to give here. : ) For you Imperialists, I measure .152" for the strap pin.

    I keep meaning to R-The-F'ing-M but discovering it's nuances has been fun on it's own. The hot shoe is hot, btw. That was a fun experiment. It worked with the simpler/older flashes. Not my SB-700. I plan to stop experimenting with flash and stick to radio triggers. Better safe than sorry.

    Jorgen, you don't happen to have an AC adapter for it do you? I'm wondering if my DIY adapter is providing ample power. I've stopped using it until I find out for sure. The amperage rating would be very helpful to know.

    I bought a rather expensive remote cable release and once it arrives I will hopefully contrive my own version and sell that back to the world (intact, of course : ). I really don't like the bulk of it.

    My 410 head isn't cutting it. I'm not ready to spend on a cube. The 405 I think will suffice. Any other advice on a proper tripod head for the beast? I'm a geared man, don't want to go back to pan/tilt, ever. Sorta limits my options. D4's are out too unless I could find a used one this week : ).

    Several of us over at the large format photography forum (www.largeformatphotography.info) have been working on stitching DSLR based film scanners. Here's a brief view of my entry, and how I have been scanning for a while now. Better than 5000 spi with a D7100, slightly less with my D800E:

    No, I have considered buying the adapter, but they go for $150+, and other stuff has had higher priority. I'm using the AA battery box on the standard body, which works fine, but for the "S" body, I go with the expensive batteries.

    Re: GX 680III Update

    Thanks, Jorgen.

    All we need are those specs and it becomes a 10 dollar affair. The camera even displays the proper polarity, along with 9V right under the extra battery cover.

    The thing lives on tiny batteries. Almost any common 9V power supply would probably work.

    Re: GX 680III Update

    I only now discovered that if you use the quick adjustment knob on the 410, you can actually make it very stiff by rotating it against the quick release direction. I think I might be OK. It's a big difference. Can't believe I didn't think of it before.

    Dont get the point, you run your film through a Bayer-sensor, a real scanner uses a sensor with real RGB values for each pixel, so what is the advantage?

    Will do. In the meanwhile ... until the strap arrives ... I think I'll try some loop connectors ... they should work.

    I've never really shot a camera as complex (tilts and swings) as the 680. So this is all new territory for me. I accidentally discovered the camera body batteries by leafing through the manual. My digital camera manuals are dusty ... but I think I need to do some serious reading for this beast.

    I tried old rechargeables in the AA box, the LCD lite up for about a second then died. I think I need better batteries.

    I tossed the beast on my Markins Ball. Seems okay. We'll see how well it works in the field.

    It doesn't like re-chargeables. Buy alkalines if you are going to use AA batteries.

    I finally found an image of the AC power supply, showing it to be 9V 2A. It seemed fine with my 1.1A adapter but I'm not going to push that anymore.

    Re: GX 680III Update

    My instant film back came in today. Rummaging through some boxes I found an unopened pack of FP-100B, discontinued a few years ago it seems. The was framed vertically, the back does not rotate so imagine the 'wings' (formed by the actual shape of the opening in the camera back) being cropped off.

    It's a lot of unused area but what can you do. I thought it might be edifying for new comers to the camera.

    This is a 100mm f/4 wide open, with a bellows factor of +2/3, which I would have happily ignored but for Danny Burk's write up. : )

    FUJI BELLOWS EXTENSION

    The light was rather dim, heavy rain outside, this was a 1.6 sec exposure before compensating, to give you an idea of the light level. I removed the waist level viewfinder and used a 4x loupe and focusing was a breeze, snapping easily into focus, nothing like my experiences with 4x5. I love working with this camera.

    Re: GX 680III Update

    I been using these to connect to a strap.



    It works, but I don't have a lot of confidence that the loops will not loosen up and slip off. I use the strap very carefully. If I didn't have the other strap coming, I'd jimmy-up a clip/clasp/tie to keep the loop from loosening.

    Re: GX 680III Update

    You're probably already do so, but passing the clip through the loop first will create a self tightening knot. Even with that, I can see it not being fool proof. A metal clip with a jamming system is surely the way to go. It won't take much to jam it, a simple 3D printed part should suffice.

    Yes! Option "B" does work. A tight fit, but it works without any modifications. straight out of the bag. A rather ugly strap, but $27 beats $200. It has quick disconnects, so replacing the strap with something a bit more suave will be easy.

    As we know the 680 is one heavy sucker. One of the fitting slipped out today, but it may have been because it wasn't fully engaged. I did a lot of walking around and some climbing on some rocks with no problems after I reconnected the fitting.

    Sounds promising.

    I took receipt of a 65mm today. 4lbs 2 oz. Oh man.

    How are you transporting the beast? I'm still looking for a backpack solution I like.

    Re: GX 680III Update

    I've used a Think Thank Airport Addicted v2.0 so far, but it's really only suitable for the "S" version and it's not comfortable to carry for an extended period of time. The problem with most backpacks is that they are too shallow. However, F-Stop is introducing a new backpack designed for cine cameras these days. It's not cheap, but this may be the solution I've been looking for. I'll drop them a mail and ask how deep the insert is.

    I'm strapping it. I use a rather large backpack for the accessories. Those lens boxes take up a lot of room. I'm looking for some padded bags for the lenses. Strapping the camera isn't very practical for hikes and such. So I need to work on a better solution. I have a very large, waterproof, camera backpack. I'll see if it fit in that thing.

    Re: GX 680III Update

    I can't find any information on the little box shown here:

    Fuji Remote Release Second Battery | eBay

    Didn't even know it existed. Talk about rare. It's only half the necessary parts to function but reverse engineering it should be fun.

    Re: GX 680III Update

    Today I rearranged my decrepit but still kicking Tamrac Extreme, at least I think that's what they called it. I packed the camera with film back and lens into the base and surrounded it with another film back, 65mm, remote release, bellow hood, and stuffed the 90 angle finder into the outer pocket. Feels not much different than my D800E kit, which typically ran 35-40 lbs.

    I used a spare divider to add extra padding at the lower back, which had a cutout in it to allow for a focusing knob to protrude, lying on it's side rather than the base against my back, which was just too tall to zipper up.

    I'll be leaving the D800E at home on my next excursion. Should be very interesting.

    Nah... that's the cheap Model I/II strap. Prices don't get interesting before you find a Model III strap

    Re: GX 680III Update

    Where are all the GX680 People ? Is digital toys overtaking the serious task like making photographs with the GX680 ? I have aquired a new tripod head for my GX680 - the Manfrotto 410 Junior Geared Head. This is a cheap alternative to 'The Cube' but solid and well built. My other reflection is that the GX680 is a cheap Technical camera although very heavy. But it's good to get exercise when outside photographing. I use my GX680 weekly and don't bother to do digi other than scanning and printing. The GX680 is simply so much fun.

    Have to agree with you there. I found a pristine one some time ago and have acquired a full complement of lenses, 50-500. A dime on the dollar. The movements on every lens is what makes this so much fun. And there is still something about film. 30x40's look great. I am sure the day is coming when I will have to horde film in the freezer, but we are not there yet. My daily work has to be digital for convenience, but the GX680 is a thing of beauty.

    I decided that the 250mm will be the longest lens for me. Of course 300 is 300 and 500 so like but they are rare and more expensive. Then I don't want to stress the focusing mechanism.

    The resolution of 6x8 chromes or colnegs are quite good and like you said can be magnified a fair amount. I like the 6x8 aspect ratio for fitting on my precut printer paper.

    The limitations are in my opinion two - the camera IS heavy and bulky. Then when I used the B time setting for more than 30 seconds in the winter some odd things happened I believe.

    But what a camera ! It is perhaps the ultimate camera that uses affordable roll film. I do not need to use it handheld for my photography but for general landscape, macro and architecture and nature still lifes it is a very good camera.

    Re: GX 680III Update

    I've had a GX680 kit for a little over a year now and when I take a trip to relax it's what I bring along. The D810 stays at home. I find it to be one of the best engineered systems I've ever had the pleasure to shoot with. It really is an absolute joy to use. I also love the return to the inherently contemplative approach to shooting film as opposed to pointing and clicking, which is all too easy to fall into a pattern with when shooting digital.

    I'm not too happy to hear that Fuji discontinued FP100C. It was to be expected though.

    I've worked up a wireless remote for it. If anyone is interested in the details let me know.

    Re: GX 680III Update

    My working hours and travel have gone totally over the top the last year, and I'm selling off stuff that doesn't serve a specific purpose for me right now, including the much loved D810. I'm keeping the GX680 gear though, two bodies, AE viewfinder and all, and I hope to do a series of portraits in July, since I'm planning a few days off then.

    The GX680, a III and a IIIs in my case, is a totally lovely camera with fantastic lenses, and I find it much more of a joy to shoot than most of the digital wonders. Time is the limiting factor.

    Re: GX 680III Update

    If one hast to sell a GX680 I think it is likely being able to recoup the expenses in buying a GX680 if not having paid all to much in the purchase. Used gear don't depreciate very much. Excluded are those who bought them new in the 1980-2000:s.

    It's sad that the loss by selling digital can be substantial.

    Nice to hear that there are GX680:s in use !

    I suppose one has to salvage one piece of a GX680 remote.

    Can you describe the color leads and which to use if possible ?

    I would like to have a lockable and/or timed remote but don't want
    to mess up a useable remote.

    Re: GX 680III Update

    Sorry for the late response. I've dug into both the III and earlier version remote triggers. It's very simple to adapt the cable to a shutter release of your choosing. The Black and the White wires are all that's required to trigger the camera. The Red wire I believe is a wake signal to turn on the light meter in the AE finder so I've disregarded that. I'm also not entirely sure if I'm correct about the Red wire since I don't have the AE finder to test with.

    I wanted to be able to quickly change over from a wireless remote to a wired remote so I used 1/8" male and female connectors mid-cable. When I need long exposures I use a dirt cheap wired remote with a locking feature. When I want a wireless trigger I use a Vello Shutterboss wireless trigger. The wireless trigger does not allow for Bulb exposures, it's simply a quick single pulse operation without reworking the microprocessor.

    I had thought that a resistor would be required, and it may actually help, depending on the internal resistance of the trigger you choose, but things are working well without one in my set up.

    When the remote is depressed the voltage drops across the Black and White wires from +5V to Zero. Black is ground, White is +5V.

    Knowing that only the Black and White wires are required means it's simple to make a non III remote work on the III body, which I've also done.

    As a double check on your cord before you wire things up, if you check continuity with a meter you should see that Black and White should correspond to pins 1 and 2, respectively on the plug, counting clockwise with number 1 as the first position to the left of the largest of the three keys on the plug, at the bottom center. If you want to play around with the camera body itself, don't forget to reverse that order, Black being pin 8 and White being pin 7 on the body.

    The only trouble I had with my customizations was finding a connector that could accept the thick cord of the 680 remote. I also wanted something that looked less cheesy than the usual suspects for 1/8 connectors. Googling 1/8" jack images turned up the ones I'm using. They look good but could be built better as they lock together a bit wobbly, but still work fine.

    (edit: the connectors I was using were giving me trouble with maintaining contact so I swapped them out for some cheapos and things are working fine now).

    I've also made a custom AA battery holder from a cheap battery holder box and the cover on the 680 battery compartment. Let me know if you would like those details.

    Thanks

    Today I finally took the step to cut my remote cord.
    Seems to be working well with a Canon-type Intervalometer Timer.

    Re: GX 680III Update

    How long a time approximately can I expect the GX680III to operate with normal CR123A batteries ?

    I had some problems with tha AA battery case so I would like to use the CR123A:s.

    Thanks

    I can't answer your question since I mostly use AA batteries. Be aware however, that the GX680 III doesn't like rechargeable batteries, so if you have used those, that might be the source of your problem.
