Help with Error - Rookie trying Copal 0 shutter with IQ3 100MP

[Wall-H]

Hi All,

I'm trying to get a set up working for shoot and i'm tripping over one use case i've. I want to take picture via cable release connected to 120 Super Symmar HM copal 0.
This is on Cambo Actus and IQ3 digital back. i'm using 12 ping connector. and i don't have cable to give wake up signal so i'm using zero latency mode.

When i'm using this combination via Electronic shutter mode, everything is working fine. Problem is, i need to trigger flash to get this working and hence i'm trying to use shutter.
When i change the digital back electronic shutter off, cock the shutter, close the aperture, and click via cable, i can see picture (or scene getting exposed to sensor) but picture is not saved.
Another very annoying thing is when i go to zero latency mode and select RZ something as camera and turn off electronic shutter mode, i simply don't get menu to press the shutter button to wake it up like mentioned in this thread. https://www.getdpi.com/forum/index.php?threads/camif-abort-capture-iq4.74195/ (i'm not getting any errors by the way. Simply picture is not coming.)

If i change it back to Electronic shutter, picture comes up fine.

I did one more thing. I connected cable from lens to the flash trigger and when i'm pressing cable release, flash is getting triggered. so There is no issue with lens or communication origin from lens.
Since i see picture coming to digital back as in sometime low portion or sometimes most of picture, i think sensor can "see" it as well but, i do not know why it is not passing same message to flash or recording picture is something that is not working. Appreciate help.

Thanks,
Rahul

Have you tried firing without using zero latency just to see if that works? Fire the shutter, then quickly cock it and fire again. I think you have something like 4 seconds. That would at least tell you if the connections are good.

With IQ2 back and 8 pin sync cable running from shutter to digital back, digital back set to Mamiya RZD and zero latency, just cock the shutter and press cable release.

IQ4 has 12 pin, IQ3, IQ2 etc the older 8 pin connector. In your picture there appears to be 8 pin to mini plug adapter and a maybe wake up cable?

I never used wake up cable + adapter combo, but I would assume that you have to close the shutter, cock it, press the small button from wake up cable and finally press the cable release.

This way maybe:

Yes i did.
In both cases, digital back simply not taking picture. If i'm using Electronic shutter mode, it is taking picture but if i'm not using ES mode then it is not taking picture.
I was able to check all point except for the 12 pin connector which goes from IQ3 port to accept pin from lens.
I do not know how i can test that.

If you are using a 12 pin cable, I believe it will not work with the iq3. At least it doesn’t with my iq260. I have to use the older 8 pin cable. The 12 pin only works on my iq4.

I did that. In fact i saw the video you recommended. The part that is not working is when you press cable release, Picture should get recorded. It flashes on the back screen but picture count simply doesn't move forward.
Funny thing is, in electronic shutter mode, when i was taking picture, flash was getting triggered, (so i know flash connection is not an issue)
i can hear shutter, uploaded video here.

It could be the combo of wake-up cable + 8pin adapter. Do you have a PC to 8pin cable? Also try connecting your flash trigger to the copal lens to see if it’s functioning properly. If it doesn’t fire your strobes, it might be your lens.

i guess the IQ3 port has 8 pins and cable has 12. So i've wrong connector. I guess i've to just order part that takes the pin and gets it till 8 pin part ? only that will do ?

I don't have it. But i guess i've to order it. I think that is issue.

Yeah i tried this. When i put that pin to Controller, It fired flash so i can confirm the first part of that cable is working. I'd no way to test other part and that seem to be problem. I'll just order it and try if it works. God knows when i'll get that part in chicago but i'll keep group posted.

Looks like you have the wrong cable. I'm actually surprised the 12-pin head would even fit the 8 pin receptacle. Go figure. I think I have an 8-pin cables sitting in some drawer and would be happy to drop one in the mail to you if I can find it. However I'm about to head out of town so I can't get to this immediately. In the meantime, there's someone offering one for sale in the buy/sell forum. Whatever the case, I think you'll need to a wake-up cable to plug into it - I can't tell from your picture but if there's a little button on the end of the 2.5mm plug, that's what you press to wake up the back just before firing the leaf shutter and flash. Hope this helps.

yup. I wrote to someone who posted earlier and i got few other messages from friends on this site mentioning about they having it as well. I'll test again and keep this group posted but i think this is it. Unless something new errors out, i think this is going to be solution to my problem. Thank you @jng !!
