A couple of days ago someone posted a pano made by a Canon. It was very nice looking night pano and in strong moonlight it looked like if it was daylight. (ISO800 at 10s) So I went out in the swedish darkness hoping to do something with what we have. It was really really dark, no moon and few stars.
The Sigma can only do 30s so the picture came out 2.5 stop (ev) underexposed. So from ISO800 at 30s it becomes ISO 4800. The second shot is something like ISO2000 and you see how much less noise there is.
