I reached out to Hasselblad support yesterday and they got back to me pretty quickly to say "…we will relay this information to our R&D team for further review. "I hoped that the "Remove checkerboard patterns" does the trick, but it doesn't. Also C1 can't do anything against.
I was in contact with HB regarding some Phocus issues with the "Remove checkerboard patterns" and thy did some updates in the last 2 Phocus versions. There is an update coming. Maybe they already know this Problem.

As I don't have a CFV100c I can not make my own files. I can't send HB your files without permission.
The camera in the article has a SK lens mounted to it. I'm not sure which one though. At the end of the article, they provide an email address to send your questions to. I reached out with our findings in this thread. I also asked what lenses they have tested and if they have seen any similar issues.Alpa did a blog write up but I haven't had time to read it, idk if they said anything about it or not:

NEW Hasselblad CFV 100C on ALPA cameras | ALPA Log
A Trifecta of Imaging Possibilities and a Revolutionary Digital Back for Technical/View Camera; Publication: Feb 09, 2024; Update: Jul 18, 2024www.alpa.swiss
Since Alpa no longer sells the SK XL lenses I doubt they would've tested them. At the end of the day I'm not sure it's fair to expect HB to have tested the SK lenses either since they are no longer made, but idk if the same issues pop up with Rodenstock lenses. We need to keep in mind, at least regarding most SK lenses, that they are legacy and no longer produced so there is a risk of lack of manufacturer support even with continued use and as technology develops. It's definitely worth contacting HB support and letting them know. Rodenstock should be a different story.
I couldn't get a tech cam demo from HB when I was interested in the H6D-100c (even after I bought the accessories needed to pair an H5D back with a tech cam out of my own pocket), and I'm not sure they are overly concerned with that market based on my experience and interaction with them regarding tech cams. From my own experience using tech cams in the field, I'm pretty convinced at this point that GetDPI is a large part of the tiny population of photographers and the only corner of the internet that cares about tech cams, or even knows what a tech cam is....aside from the folks at Arca, Cambo, Alpa, etc., maybe the Chinese market.
All that said it's still a bummer though. Seems it can be corrected in software so maybe they'll update Phocus, but just be careful with extreme movements in the meantime.
I chose to not cold-call, but deliver the message via my dealer. She's going to address this with Hasselblad. Maybe that's also an option for you?I reached out to Hasselblad support yesterday and they got back to me pretty quickly to say "…we will relay this information to our R&D team for further review. "
Feel free to send the files along, you have had success getting help from them.
That is unfortunate. The lines are a bit harder to see than on Warren's samples with the 35 XL, but I see them.i just rechecked a test shot i did a few weeks back and can confirm that it is an issue with the SK 43XL as well (unfortunately!!!)

it's most evident in the upper left corner, visible as dark horizontal stripes.
this was shot on an Rm3di with CVF100c and SK 43XL at f11, focused at infinity (decentered on the camera -5mm vertically and 8mm to the right)
i also did test shots with a Rodenstock Sironar 90 (symetrical design) and pushed it to the max shift position of the Rm3di and have zero "stripes" to report
The vertical line like looks like 'normal' sensor tiling.Have a look at the post by user Bokesan here: https://www.dpreview.com/forums/thread/4748591#forum-post-67549207 It's the 11th one down. He processed a file in Affinity with HDR. This reveals the problem in black and white, literally. There's the added problem of a vertical tiling line.
Normal is good!The vertical line like looks like 'normal' sensor tiling.
Yeah, if you crank everything up you can see it, but it's not an issue in 'normal' use.The vertical line like looks like 'normal' sensor tiling.
I played with your picture for while in RawTherapee 5.9.i just rechecked a test shot i did a few weeks back and can confirm that it is an issue with the SK 43XL as well (unfortunately!!!)
