The star eater issue with Sony cameras was well documented in the past. I am wondering how the latest models fare in this regard.

Has Sony fixed this or made it less of a problem?


It's a feature of how they do their lossy Raw files - just save Raws as uncompressed or lossless compressed (as the camera allows).

That’s incorrect. It’s a problem of several brands and irrespective of raw format, compressed or not . You can Google about this; there are hundreds of threads all over the different forums. Some models have it, some not and it’s baked in hardware.

I think Sony has a particular issue but yes, part of the problem is indeed not related to lossy raw and I should have spent more time replying. What I was really saying the is Sony lossy raw encoding produces artefacts when you have large brightness variations in 16-pixel horizontal groups (of the same colour, so 32 pixel groups on the sensor) and you should consider not using lossy raw for Astro shots if you already have Sony.
