In the 1st close up, to me the 260 shows a more blotchy noise in the blue areas, especially the blue line running around the bottle, and some in the large blue areas below. Details to me look about the same.
In the 2nd crop, the shadow area below piece of food ( I assume that is what it is) is definitely cleaner on the 260, but again the blues show a bit of more noise.
Thanks for posting
The IQ 260 looks really good. Even the shadow on the grey paper is really quite clean for such a tough subject (textureless grey background and long exposures). It does show some patchyness and what looks like
very small amount of banding, but I'd atribute that to light reflecting off the glass.
If you consider how this will work with a typical night scene I think it's safe to say that the results will be quite brilliant.
