Updated, but not solved. The update will be here at the top in italics. Everything below italics is the original post.
I have been in contact with Canon Tech Support - first by email. Three different technicians, a lot of back and forth questions asking pretty much the same thing that is scattered through this post. No one had any suggestions, but just a lot of questions on what I could have been doing wrong, none that panned out though. Finally did the phone option, and got a little further. This tech let me send in RAW files, could actually see what the concern was. He was also an astro-photographer, so when I explained various things, he understood what I was talking about. He also confirmed that I was not crazy... there is zero EXIF data for IBIS, only IS through the lens, which did not apply here. So again, we do not know what caused this, or what to do.
I asked "Is this the type of movement one would see IF the IBIS was still on, while on a tripod?" He replied there would be movement, but he cannot find anything saying it would be a small rotational type of movement. So now we are both trying to do some homework to find out.
This brings up a question for anyone here... Do any of you have any idea what type of movement that YOU get in your camera if you leave IBIS on (with a lens that does not have IS) while on a tripod? Out of all of my cameras, this is the only one with IBIS, so I cannot test this out myself since the technician and I agreed this would need to be tested with a different camera. I'm stuck and at a point where I have zero other resources to figure this out.
Thanks!
I have a question on some night sky images I have been taking with the R6 Mk ll. I should mention first that I am not new to night sky photography. I've been doing it since pre-digital days. I've also shot a lot of night sky images with 4 different Pentax DSLRs, 3 different Canon DSLRs, and now 3 different Canon Mirrorless bodies. The R6 Mk ll is the first camera I've experienced the following with.
If you look at the two attached images, one is nice and clear, the other seems to have a bit of a rotation to the whole image. I've only shot night sky images a few times with this camera. Last month I saw about 10% of my images had this weird rotation. I wrote it off as shifting sand around the tripod. Last night I was out taking about 100 shots. Very sporadic, but roughly half of them look like this. This last one was taken in the parking lot (solid ground - no shifting sand).
Few notes:
* Camera set to Manual mode
* IS turned off in camera
* The tripod is solid, tight connections on legs and ball head, and far from being underrated for this gear weight.
* I've used two different lenses where this is happening. Rokinon 14mm F/2.8 EF mount... Venus Optics Laowa 15mm F/2 RF mount. Both of these lenses are full manual - no auto setting, so the camera is set to shoot without a lens.
Am I missing something in the settings that is new to this specific camera? I've never had this happen on any other camera. Also, I only see this in night sky shots, when on a tripod. Day shots, on a tripod are never a problem.
