    Újabb PR cikk, ami mehet majd a süllyesztőbe. A jelenlegi jobb CMOS szenzorok QE értéke (Quantum Efficiency) 50% körüli, a látható fény ekkora százalékát hasznosítják.

    "The reporter who wrote this story misunderstood the original Nature article. The performance boost was actually relative to previous graphene sensors, not relative to traditional tech. Apparently, even these new graphene sensors still stink on ice in terms of visible light performance when compared with CMOS. They're great for non-visible light, though. :)"

    Despite the poorly written article, this sensor tech is very *insensitive* compared to what you currently have for visible light technology. It's a 1000x improvement compared to previous wide-band graphene detectors, which can sense light from the visible out to 10um mid infrared (your camera can't do that). So no, this won't help your camera photograph at higher ISOs. And current camera sensors are within spitting distance of the theoretical physical limits on low light performance: while they've improved tremendously over the past couple decades, the noisiness of low-light pictures with the best current generation sensors is close to what you'll always be stuck with --- its the result of there being a finite number of photons, with sqrt(N) counting statistics fluctuations, available for even a "perfect" camera to see.
