Thanks for confirming my results. Many have made the point that Raw is clearly sharper than jpeg. I've been puzzled by this as my tests always showed hardly any difference. On another test I did the jpeg showed a slight cluster of a few pixels on a bright highlight.

FYI the needle on the left was the RAW version.

The logic of the jpeg encoder is to first compress colour and preserve brightness and resolution. Then progressively reduce the number of brightness levels and resolution as the compression factor is increased.

It would be interesting to compare the difference in colour on RAW and fine jpeg.
