The very best the SD10 can do concerning signal to noise ratio is 42 dB at
ISO 100 compared to 50dB at ISO 200 for the Canon EOS 1D Mark II (the very
best).


These are very interesting figures. Did they also test the Nikon D70
and Olympus E-1? What were the signal to noise ratios for those
cameras at ISO 100 and 200?


I'll show you what the SD10 produces at night exposure (ISO 100, 30sec)
and what the D70 produces (ISO 200 =lowest , 30 sec)
