Most all Sony cameras provide three NR methods:
1) NR set to off (first image), low (second image) or normal (not shown);
2) Multi-frame NR - shoots 3 frames in rapid succession and merges the images;
3) Handheld twilight - shoots 6 frames in rapid succession and merges the images.
The following 100% crops - images were taken in the order listed above, all at ISO 8000 with no pp, very low light indoor shots. The last image is full image resized to web with no other pp. The lighting was so low, that this represents an extreme situation for Sony NR.
It looks like HHT is the best of the lot. The 6 shots fire off in under one second. All shots taken without tripod and triggered with my finger, not a remote or timed release. It is incredible how the Sony software merges the shots so well when it is a certainty that there was some camera movement from frame to frame. The pano stitching is equally impressive.
