i remembered my first digital camera from olympus was c1400l using mmc card...which cost me $1500...now that ccd sensor is on every consumer phone camera...

these ccds will be very economical to produce and cheaply available...

if the pots are circular, then the surface area increase is not 50% but additional ~150%

Hi,

Not sure about the new D300s/D3s/D3x, but D300 and D3 still use the same noise reduction "unfriendly" RAW file.

Anyway, I don't think Nikon will stop their current method of producing the RAW file as this'll reduce the noise advantage over Canon DSLR. I just hope Canon don't follow the Nikon way of producing RAW file in the future.

Have a nice day.

May I know what kind of hack is that? And what additional functions does it bring?

Frankly, I prefer a full frame 5D Mark II (which I am using now) than a APS-H (1.3x crop) of the 1D Mark IV. Although it gives longer reach iif using photographic lenses. Anyway, in astrophotography, the additional fps is useless and the weight is a bane rather than a boon to an astrophotographer.
