Good perspective on the relative merits of mono vs colour imaging.

My take on it is what people can afford. It is not an argument of what is best but but how much one wants to invest (waste according to SWMBO). Even my modified Canon 5DH cost many thousands of dollars. At least it can be used for terrestial photography and it really excels at low light.

I am sure as time goes by I will invest in a 'better' imaging sensor. Unless it can produce a markedly better result I will persevere with what I have.

Meanwhile I have worked out how to overcome the 12 bit limit on the Canon 5DH. I can also cool (-12 degC) the whole camera to minimise thermal noise and I have got a lot of experience and fun doing it.

I also think that if A Canon CMOS sensor was cooled to the same extent as any CCD it would leave it far behind. Without the Bayer filters the QE would be close as well. A 16bit or better A to D would also help.

There is never a 'correct' answer only the current 'best'.

The problem as always is that quality versus cost is a function that follows an inverse exponential.
