hi, I'm working as a freelance photographer at an photography school.
We are working with 4 Leaf Aptus II-5 digital backs on different camera like Hasselblad 500, Mamiya RB67 and Cambo Ultima D.
They are 95% of the time used tethered to a iMac 2011 model, with OSX 10.11.6 using Capture One 9, one iMac runs 10.12.2 with Capture One 10.
Often we find big problems to connect the Aptus backs to Capture one, although we also use FireWire repeaters, but without succes. There is also no logic in it.
I used a back connected with an iMac on the 20th and 21st of February, my colleague wanted to use this combination on the 4th of March and couldn't get it connected. The back and the iMac weren't used in between those dates.
We use these backs for a few years now, i have to say it looks like we have not so many problems as we used to have, but still it's annoying, for us but also for the students.
Any one who has the same experience, or knows a good solution?
