I'm hoping I can get a response from support for this. Here's a Google drive link to videos showing the problems.

I just purchased my first BM camera last summer, the Cinema Camera 6K. Everything seemed fine with it until I took it to my first shoot last October. The Iris was unseating randomly shown by an "*" and the inage shiftingup and down. So my short narrative consisted of my having to re shoot scenes multiple times as the image would shift up and down.
I got on the phone with someone here and they told me to narrow down the issue, whether it was the lense, or the lense adapter. Well, I only have the one lense, Sigma 24-70 EF mount, and an EF-L mount adapter. However, the issue resolved when I reset the camera settings. Issue resolved? Temporarily, but recently the issue came back, but I'll get to that later.
Soon after that, I started having an issue with battery. I mimicked my friend's setup, with an external v-mount battery. Supposedly it's supposed to be charging the internal battery, but I soon found out it wasn't. I had my camera setup to film my son's birth, and asked a friend to periodically check the external battery and hot-swap it when needed. Well, they found the camera bugging out and it stopped recording. The voltage would show the voltage of the internal, rather than the external. If it got too low, the camera would bug out, flash and fail to record. So I would take out the internal expecting it to run off the external. The camera would stay on, but still flash and fail to record. What?
Trying to put that off so I could be with my wife, I charge the internal. Only after replacing the camera with a fully charged internal, would the camera return to normal. My solution after that point was to only run off my external.
Some time after that, the iris issue came back. I tried resetting, nothing. I searched these forums and found similar issues, and tried them. One solution was to roll back an update, nothing. I'm now back to the recent firmware, and still nothing. I finally was able to pay a trip to my friend to work out the problem (we live in different states which is why it has taken so long for me to find a solition.) He set up his 6K with the same setup as mine. Same lense, and adapter. We tried swapping lenses, unblinking, etc. To try and replicate the issue. We could not get a consistent reproduction.
We then tried the battery issue. Consistently, with my external and internal connected, my 6K would draw power from the internal randomly. At attempting to hot-swap my camera would drop power, go black for a second, then recognize the internal. We then connected my external to his camera, hot-swapped and showed no loss of power on his. He then concluded that this is definitely an internal issue, an nothing that I could have caused. He suggested I report this here to the forum.
The Google drive has two videos. The two short ones show the iris unseating, and the longer one shows my friend and I testing the battery on both cameras and hot-swapping.
I would like to know what I can do to remedy this issue. This has been my first high-ticket purchase for filmmaking, and I haven't been able to properly utilize my equipment as it has been faulty from the start. It hasn't even been a full year and this whole thing has honestly been devastating me. I would appreciate any help from the support team at Black Magic.
Thanks, John
