Just wondering if anyone has heard news about whether Sony will start using the higher-resolution camera CCd's that are out (like the GL2, Panasonic's DXV100, etc.). From what I've heard, the PD150 had the best image but may need to play catch-up.
Anyone heard anything..... Bueller?
Thanks,

The CCD pixel count in the PD-150 is above the number of pixels needed to construct a 720 by 486 pixel color image.
The high pixel-count CCD's pay for that by generally having a lower sensitivity to light. It is the number of photons falling on a sensor that determines the luminance signal. That is, larger pixels, more light sensitivity all other things being equal (AOTBE).
It is just like silver-based film. Fast films are grainy because larger grains are more sensitive.
From what I hear, the PD-150 still has the best image and the best low light performance. Pretty unbeatable. Doesn't mean someone won't eventually beat its performance.
BTW, Sony probably makes the Panasonic CCD anyway. There are only 2 or 3 manufacturers of camcorder CCDs in Japan

yeah i think Mike is right
in real world no company builds up it's own camera till the end. sony does'nt make good lenses for opitcs, so they buy them in. sony is a good CCD maker, so why do not sell them?
sony guys told, that they found surprisingly DSR-300 CCD chips in JVC G500 cameras
as one of our customers says "i don't care what company made my camera, if it's sony"
the same is going on in computer world, you find only two main makers for pc processors
