What do I need to get a Fuji GX680 working with CFV 100C?

[Steven M]

I bought this adapter on eBay. It’s coming from Japan.




What else do I need to get the CFV 100C working with the GX680?

I’ve seen a few references to the Kapture Group setup on here. I think I’ve even found one I can buy. Is the Kapture setup needed in order to work with the CFV 100C? Or was it only needed to work with the older Phase backs?

The challenge the Kapture Group adapter was overcoming was 1) providing a wake up signal prior to the capture and 2) overriding the behavior of the flash sync port to reflect the start/stop of the actual shutter speed

That adapter was required for Phase One backs that used a two-shot architecture. I don’t have any help to offer regarding what would be needed for a CFV.

Do note that 33x44 on a 680 is a very heavy crop.

Fun body that 680; good luck!

CFV does not need a wake up signal (or does not take advantage of a wake up signal to reduce power consumption and sensor heat, take your pick). you‘ll need the cable supplied with the back that will go from the flash in port on the XCD to the PC flash port on the body. Only thing I don’t know is if that adapter will still allow infinity focus but getting the CFV backs to work on about anything is just that cord then setting the right camera body setting in the menu-“Any-Flash Sync” or “Any- Electronic Shutter”

Treat it like you're connecting it to a 'dumb' technical camera - i.e. connect the sync socket on body to sync input of the CFV using a regular flash sync input cable (I think there's one supplied with the back).

You can also use it in electronic shutter mode without a cable, but you need to keep the lens in 'bulb' (open) mode and set the shutter speed on the back. You won't be able to use flash with electronic shutter; rolling shutter distortion may occur with fast-moving subjects, and banding can happen under flickering artificial lights.

I often use the electronic shutter with my Hasselblad and ALPA cameras, setting the shutter speed on the CFV50c II digital back instead of the shutters in my lenses. If the weather is nice for a landscape shot, it's the electronic shutter for me.

The digital back adapter arrived. All is well with getting the back on the camera.


I have the front adjustments all sorts out out of whack just experimenting. This is already really cool.

This is the first photo. I didn’t even get flash going. Just a modeling light, so forgive the exposure. I’m no pro. Just a guy that likes to tinker with photography.



I’m coming up on a small problem. After I take a photo, the BATT OK green LED and amber WARN LED flash alternating. The shutter is cocked, but I can’t take another photo until I power cycle the camera.

This is true in either position of the back adapter, and either position of the main camera switch (single, continue).

Any ideas on what I can do so it will take a second photo without the power cycle?

Of course the solution is right in front of me.. for anyone else that may run into this, there is a small interlock button on the mode selection knob. It slides away from the body, allowing the knob to rotate past the CONTINUE position into the CONSTANT position.



Now we’re cookin with gas!

Lastly (for now).. this is the slippery slope, right?!

 

[Steven M]

Once I had that sorted out I was able to get the flash working without any fuss. Using a Godox trigger.


This all just plain works!


The setup


This is all for product photography for my electrical testing tooling that I make.


I’m hooked! Next up is shooting with film on the same setup to see how that turns out.
