Aha, yes indeedy - and because the film image is grainy, there are not the
wide areas of continuous tone to be jpeg compressed.

Thanks Moose

Remember that you are looking at JPEGs, with lossy compression. 
2608x1948 pixels is 15,241,152 bytes, or about 15mb. The JPEG image is about
1.15mb, about a 10 to 1 reduction. You are almost always going to see some
compression artifacts at that level. Whether it is a result here of shooting
in HQ mode or later compression for the web, the place where JPEG
compression shows up first is in areas like sky.

So the banding you see doesn't really say anything about the capabilities of
the camera in tonal range.
