duqov: Can somebody point me to a website/formula where I could calculate which aperture I need if I want: 1) 1/2.3 sensor, 2) equivalent of 85mm FF view angle and 3) equivalent of 85mm FF, f=2.0 depth of field? Would it be about f=0.2? How big would such glass be? Still smaller than FF 85mm f=2.0 Why is nobody making such things?
As a Nokia 808 owner I am convinced that with small sensors inevitably getting better, things like that will surely become the future.
