These all, I repeat all have problems with colour and aliasing and moire due to the nature of the sensor.
There are ways to reduce these problems but nobody has yet avoided them all.
The sensor design is fundamentally at fault, it’s a pattern of RGB sensors with holes between the different colours.
These holes cause colour errors, someone has to guess what colour was in the hole, yeah I know they say they use sophisticated algorithms but that’s just a smart way of saying guesses.
The holes cause aliasing and moire which the manufacturers reduce with OLPF filters, optical low pass sound a lot better than diffusion doesn’t it?
Oh yeah, that’s what they’re doing, reducing the resolution to reduce the errors. Brilliant!
Just what I want, a camera with faulty colour and a diffused image…
