Originally posted by jshurak I hear your endless debate on the amount of pixels, but I've also heard people mentioning the desire for bigger pixels. I'm not familiar with this. What's the difference?
there are two discussions going around, one for increased Mega Pixles the other for full frame sensors.
There are two different approaches to increasing the Mega Pixles, the first is to retain the same sensor size and just put bigger sensors, this is what is pushing the full frame club (dare I call it that) the other approach for increasing the Mega Pixle count is to keep the same image sensor size and make the individual sensors smaller.
The problem is, as individual sensors become smaller, the noise that the sensor increases, this is especially apparent at high ISO. Noise also increases with temperature.
The full frame club is pushing for full frame because the pictures would have less noise if each sensor was bigger, compared to the same Mega Pixle count from a smaller sensor. This is especially useful for shots that are done at low light
What you should expect is that for each new generation of sensor, the noise should reduce (for a given sensor size). Manufacturers are at present taking advantage of this by increasing the MP count, but soon that will taper off, and the emphasis will be to retain the same MP count and push image quality, especially at low light (High ISO).
