What sort of effective ISO do they run at?
The reason I ask is that the gear I have is pretty much the best you can get for low light in the traditional photography world - are the dedicated CCD imagers really a step above that?
A combination of my lenses being f/1.4 to f/2.8 and the Canon 5D can do very good 800/1600 iso exposures - it can suck a lot of light in - I'd sure be interested if the ccd was better but it surprises me if they are
(of course I'm discounting research/university grade stuff when i say that)
thanks
