It’s broad vista ahead of Q.
Jul 24, 2014

This is partly in reply to the "Embarrassment" thread.

Many have been critical (from mildly to vehemently) of Sigma for abandoning the classic Foveon formula, or skeptical about Q. They seem to have neglected a couple of important facts:

1. Like any good technology, Foveon in classic 1:1:1 configuration is good only within certain parameters. There should be, for instance, a point beyond which any higher pixel density won’t yield more “dividend” in resolution, as unwanted side effects will outstrip any possible benefit. And since lower layers in Foveon sensor receive much less light, they reach the “breakeven” point much earlier. It’s reasonable to think that Merrill is close to that point. If Sigma wants to maintain its resolution lead and yet improve on other IQ measurements, they have to find new solution. And variable pixel size in different layers is indeed the most logical development for Foveon.

2. Human visual perception is a little more complicated than elementary math such as 1+1=2.

With these two facts in mind, it’s really not too hard to come to terms with the amazing IQ we are seeing from Quattro. Foveon engineers and Sigma management should instead be applauded for their innovation in taking advantage of the phenomenon in physics and human visual perception to achieved IQ comparable to M (similar sharpness and fine details, yet better colours and low light performance) using only 2/3 the amount of pixels.
