Is this only in the JPEG. I don't have the subscription to the mirrorless section but it seems Lloyd meant the 8-bit lossy compression. That would mean JPEG. It's interesting to know if it also happens in RAW, and I wonder why no one has noticed that before.
And RAW from Sony is compressed, but lossless. This is the same with any Sony cam I think, and I have not seen anyone complains about that.
Sony does not use a lossless raw any longer (except possibly for the A99 as mentioned below). I have been complaining about a possible issue with Sony's lossy raw compression and a few of us believe we have seen evidence of a lack of smooth tonal transitions in, for instance, skies which can look posterized when pushed in processing. I was not aware that Lloyd had proven there is an issue but if he has, it would not surprise me. As I have mentioned previously, my non-lossy Sony a900 24MP raws are the same size as the lossy raws from the A7r. On the A900, Sony did offer the choice of a lossless raw and a lossy raw. Since then, Sony only offers a lossy raw, though some A99 users say that camera actually records lossless raws when shot in single frame mode.
Btw, Sony does admit they use lossy raw compression but claim the difference between it and their older lossless compression is not visible.
