Originally posted by ddamski hose 50 mp are yummy as the ISO and dynamic range. And the sensor of the 42 mp has some potential,
50MP on 645z is different, the sensor has 4x bigger area than on APS. So the density is about 12.3 mp on APS.
The 42 mp sensor has smaller pixel than those on 16mp aps sensor. Although I have no doubt tech is progressing and the new sensor should have better low light performance than 16mp old pas sensor, I doubt it has dramatic improvement.
I want a FF first for the field of view, second for its high ISO perforce, but not really for higher resolution.
My computer processes 20MP JPG files well -- it is a mainstream PC, not too fancy, but not out of date either, I just upgraded. but is slow if I use Pentax Utility Software to process the RAW files from 16 or 20 mp cameras. I can not imagine what is going to happen if files are from 42mp sensor.
