sony hdv lowlight hierarchy
Based on the information released so far, am I right in assessing the sony HDV cam lowlight hierarchy (at 1/60 shutter speed and 18db gain) as follows:
FX1/Z1 - 3 lux FX7/V1 - 4 lux HC5/HC7 - 4 lux HC3 - 5 lux HC1 - 7 lux Sony's giving the HC5/HC7 a lux rating of 2 but that's at 1/30 shutter so at 1/60 I assume it's 4 lux, does that follow? I'd be surprised if the HC5/HC7 had the same lowlight as the FX7/V1 but unless I have my figures wrong they have the same lux rating ... Have I got this right? |

From what I've read and from my own experience with the FX1 and HC3, that looks about right.
Spot might be able to add feedback, since he gets to play with all these neat toys as soon as they are released. |

yup, I'd say that's correct, depending on whose lux rating you're using.
The HC5/7 are "mis-rated" due to the DSP and how they work vs how they're measured, but not so much so that I'd argue. DSP doesn't change the measurement, but does change what we actually see.

This isn't scientific, but my gut reaction is that the black stretch feature definitely helps in low light situations. I don't know how this impacts actual Lux calculations, but if I were shooting in dark places I'd want a Z1 instead of an FX1 or a V1 instead of an FX7.

Aren't the ratings of 3lux for the Z1U and 4lux for the V1U based on 1/30 as well? I'm almost positive it is... |

Getting more "low" out of low light shooting.
A nod to Boyd's observation--With Sony's A1u, I've learned to keep the black stretch on and if the subject is not moving much (I video a choir) I can dial the shutter speed down 30 instead of 60. Gives me a bit more exposure latitude.
