What would more MP mean to you ?

Re: What would more MP mean to you ?

The problem with that is typically smaller pixels = less low light sensitivity.

If you look at CCD sensors for example, the usual thing is when pixels get smaller the QE (quantum  efficiency - a big word simply meaning sensitivity or efficiency of the sensor turning light into a signal to produce an image) goes down.

One exception I know of is a Sony ExHAD CCD sensor which has very small pixels and very high QE.

So if anyone can do it it would be Sony. It appears Sony provide Fuji with the base sensor at the moment (that could change with the organic sensor) so perhaps in a later model.

The organic sensor has wider dynamic range so perhaps this could be a feature of that sensor when it comes out - too early to know.

Fuji also has a patent for a Xtrans style pixel arrangement posted here recently that would have much better low light performance and that potentially could give you what you asked for.
