I have made it a point to email Sony once a week about the ever present star eater issue in the a7riii. They never truly gave us the ability to process true un adulterated raw data. I can see star colors and cores being eaten up in long exposures but just to get a second opinion, im curious what you think. Does this cropped image appear to have been negstively impacted by star eater? Other than the poor non round star profile created by the less than perfect gm 24-105 I see faint background stars which have been desaturated and foreground higher mag stars which were for some reason able to accumulate color data. I did not buy this camera to do astro work but thought it would be a bonus to get clean milkyway shots. After seeing how spatial filters impact thee images I decided to bust sonys balls about this issue. What do you think?
Plus a bonus Somys response to my star eater complaint after providing these images
Thank you for contacting Sony Digital Imaging Support Team.
I understand that you have some question about the star eater issue from the images you took using your ILCE7RM3 camera.
We are able to access the sample image you provided, the sample image of the sky is normal and star eater issue is not present. If the star eater issue is present you will not see any bright spot on that image. And also, we no longer received any star eater issue since that the new firmware update was released for our ILCE7RM2 cameras. The star eater issue happens with the ILCE7RM2 not with your ILCE7RM3 camera model.
Should you have any technical questions or concerns, please feel free to send us an email. Our support hours are Monday to Friday 10:00 AM - 9:00 PM; Saturday 10:00 AM - 7:00 PM EST; Closed on Sunday.

I applaud your efforts but am confused by your presentation of your case.
In the past compelling evidence was presented for offending camera models by taking images with settings known to trigger the spatial filtering,
compared with images where a known baseline reference (like with settings where the filtering was not triggered).
My experience of your links doesn't do this. I am missing something? Is it an animated GIF that isn't playing for me?????
I see a widefield, and a crop 'untitled.'
It also seems clear "Carl" doesn't understand the concepts involved, and wasn't visual persuaded by your images (or at least is parroting someone else who wasn't persuaded by your images)....
Seems you got some kind of audience with someone there at Sony, with an invite to continue to email.
If your links are your best case, I'd consider trying with a better presentation as if you were explaining it to a 5th grader....
There are many ways that are obvious that Sony hasn't eliminated the secondary unintended consequences of their spatial filtering algorithm,
but since you have access to the a7riii and want your point two be heard,
please work on the delivery. Take for starter's Wei Ho's suggestion......
I'd also advise word careful word choice. Sony and others are influencers are now using "star-eater"----but unfortunately the term is very results-oriented.
As Mark Shelley and Jim Kasson have made efforts to define it as a spatial filtering process,
IMO we need to help Sony admit what is going on is caused by an intentional data cooking process.
If say, Carl for example (imagine he wasn't just a parrot of scripted information posted on his computer screen),
had to address whether or not Sony in the a7rIII with the recent release was still intentionally cooking the data (process),
instead of answering about very vague or pixel-peeping dots results,
than he would have been less able to state "If the star eater issue is present you will not see any bright spot on that image."
Using the term "star-eater" has allowed at least Carl to frame the debate to a very specific set of results,
rather that the whole issue that
an intentional data-cooking is producing secondary unintended detrimental results in imaging stars that could otherwise with the same gear be imaged better....
I think those that want Sony to completely fix any negative effects are not being realistic.
Please can we just get Sony to see that there is a population of users that want Sony to give them the option
of whether Sony's latest spatial filtering data-cooking will apply to the desired images......
How about just saying "Hey Sony, I get you haven't been able to completely fix it.
Just give us a menu option so whatever current spatial filtering doesn't have to be applied to our photos of the stars........"
