You need f1.5 in bright light, that is if you want less noise in pics, you got samples, see for yourselves.
What do you mean by the camera having two apertures? What is the mechanism by which the aperture changes? Can someone elaborate it?
I read these articles frequently, but always forget them. Thanks for the reminder, really does help the none photographer in me.
Still amazed that Sony have made such a half hearted attempt with their camera this year. Doubling the DRAM could have been the deal breaker. I know they have given it in 1080p now, but for half the time. Samsung deserve to be the biggest Android phone supplier. Something tells me that Google will step up further though. They appreciate that the camera aspect is a terrific selling point.
Kodak wasn't the first one in 2008 with variable aperture on a cameraphone. The Thai company Samart launched their i-mobile 902 in late 2006 and this also had two apertures. The camera sensor was Sony's ICX495 1/2.5" CCD which were also in some digicams like the Canon PowerShot S2. It also had a mechanical shutter, Xenon flash, lots of camera features like slow sync flash. But it was tricky to use. It was tuned for quality which meant that shooting handheld indoors was very difficult unless you had a few drinks before to steady your hands.

I think LG's KG920 came out around the same timeframe. It also used the same ICX495 sensor.
