For comparison, the Nikon D4 (a digital SLR) can shoot video at ISO 204,800, and it can resolve details in the dark beyond the ability of the eye, and I suspect this new sensor is more sensitive — or, at least, far more noise free — than that. EDIT: Judging by some photos I've taken of the night sky, with an f/2.8 lens and with a shutter speed of 1/50s, you need an ISO of around 300,000 to get enough brightness. If o…

Didn't he use the same lenses used by NASA on the cameras for the Apollo missions? I think the larger aperture gave better low-light exposure during the candlelit scene (and may have inadvertantly fuelled conspiracy nuts that think the moon landings were a hoax because they think the sunlight reflected off the regolith was a secondary light source).

I would love to see such a sensor for photos instead of video!

of course we would, but photographers wouldn't be too impressed with only capturing 1920(?)x1080 resolution.

This gains it's light gathering abilities by simply having much larger "pixels" on the sensor, which can collect more photons. This is the same principal used on the highest end canon eos body, the 1DX, which has slightly lower resolution than the 5DmkIII in order to gain sensitivity.

In a way it's kind of simple, isn't it? Having "only" Full HD on a 35 mm sensor simply means you have much larger individual potential wells, capturing more photons per pixel. What I'm really wondering about is the dynamic range - wouldn't that also drastically increase?

Too bad the whole camera business wasted a huge amount of resouces over ten years on a stupid tinier and tinier pixels race.

Given the choice between 24 MP with very high sensitivity or 2 MP with ridiculously high sensitivity, I'm not sure the industry is wrong.

Is this a color sensor? The high end astrophotography sensors tend to be monochromatic, with a filter wheel placed in front of the sensor. That way, each well has 3 times as much chance of seeing a photon.

Based on the incredible looks-like-daylight shot taken by moonlight, the answer is yes, this is a color sensor.

I always find it depressing when I take a picture by moonlight and it ends up looking very much like a picture taken by sunlight, as opposed to looking like the scene looks to our eyes. Always have to keep in mind that a CCD != rods and cones.

Sensitivity is nice but as far as I'm concerned, dynamic range is the main thing that's needed in digital photography. DSLR sensors have gotten much, much better over the last 10 years but there's still plenty of room for improvement.
