Re: more pixels are better!

Image detail is affected by lens aberrations...

...and the size of the sensor.

(and many other references)

Technically, Dynamic Range is the differences between the smallest and largest recognizable signal that can be recorded by a pixel. Thus larger pixels have greater dynamic range than smaller pixels. However, this strict definition doesn't take into account the combined effect of pixels. I personally remain uncertain as to the effect of pixel size and density on dynamic range. I've seen examples that indicate larger pixels give more dynamic range for a given sensor size, and I've seen examples that indicate larger sensors give more dynamic range for a given pixel size.

Bottom line...bigger is better. You want better detail, get bigger lenses and bigger sensors.

Notice my reference to image detail rather than image quality. A quality image is something else entirely!
