Quantum Film Might Replace CMOS Sensors

An anonymous reader writes "Quantum film could replace conventional CMOS image sensors in digital cameras and are four times more sensitive than photographic film. The film, which uses embedded quantum dots instead of silver grains like photographic film, can image scenes at higher pixel resolutions. While the technology has potential for use in mobile phones, conventional digital cameras would also gain much higher resolution sensors by using quantum film material." The original (note: obnoxious interstitial ad) article at EE Times adds slightly more detail.

Re:Don't care about more pixels

I'm assuming you're french, and therefore used "objective" instead of lens. There are a lot of photogs that indeed will throw huge amounts of money at their hardware, but to be honest it's usually a useless investment.

Also, why you'd be talking about glass in a thread that is specifically aimed at sensors beats me. You don't need 700mm at f/1. Plus, any body that you use with some Canon L is necessarily going to be full-frame, meaning you don't need to be at ISO 50. With full-frame, you can without any problem go up to ISO 400 and not notice any noise -- especially with fast lenses.

To be honest, you sound more like the arrogant paps who don't understand a whole lot about photography than a decent photog. Maybe you too tape up your lens' controls, and just know that you need to be at x meters from your target to be in focus?

You say you want more portable glass. However, you're still asking for a 700mm lens. You do realise, that in order to have 700mm lens at f/1, you need an entrance pupil with 700/1 = 700mm worth of diameter? Yup, that's right, 70cm of diameter in order to achieve f/1. Not sure that's ever going to be portable, mate.

Didn't think anyone would call your bluff out here, eh?
