About the G11's sensor
Aug 19, 2009


I saw a lot of you talking about what the new CCD could be, so I guess I should post this:

Sony recently annnounced this as their most sensitive ccd for compacts. If you don't understand those specifications:
Sensitivity (G signal) - 3200K, 706 cd/m2, 1/30 s accumulation, F5.6

this is the voltage response to that specific light, and the higher it is, the less ampilification needed, the less noise there will be

Just for comparison, usually the ccd-s for compacts are aroudn 170mV! I don't know about canon sensors (since they're not made by sony, which datasheets are published), but the 12mpx sony aps-c sensor (used in nikon d90, d300, d5000) has 500mV green response! And for mobile phones the sensitivity is around 100mV (the new 12mpx 1/2.5" chip for mobile phones is 90mV)

Another important specification is "Saturation; Ta = 60°C, per pixel signal"

800mV, which refers to dynamic range, and I don't know this exactly but it's too around halfway between the conventional sensors and aps-c ones.

And this chip doesn't feature such a fast readout to enable 720p (well they can read out 690 lines they could have upsampled it of couse...)
Best regards, SteMa

Canon, you can... Nikon, unique...
