Re: Quattro = ratio 1:1:4 .... ???

So, that's a change: ratio 1:1:4 for the number of red, green, and blue megapixels, respectively.

So does this mean the sensor is more sensitive towards blue? What's the advantage here really in simple words?

Best regards,

Until we actually see images this is guesswork, but by increasing the blue/top layer to 20mp we will get higher resolution.

I'm guessing that the green/middle and red/bottom layers had so much noise in the Merrill sensor than reducing the resolution to 4.9mp and interpolating in the final image has minimal quality loss.

Shooting for fun and memories.
