Anyone got any sample footage from the A1U? I am looking at going from SD to HD! and I would like to know why this camrea is so cheap, but still so "raved" about!
Thanks,
Pat

I don't have A A1U but from what I,ve heard it's a good cam
but not that great in Low light.

CMOS is better in situation where you have a lot of lights (which is why the 1/4'' CMOS V1U can compete favorably against other 1/3'' CCD cams) but it's going to be worse in low light.
A quote from an article comparing CMOS and CCD
"In a CCD sensor sensor every pixel's charge is transferred through a very limited number of output nodes (often just one) to be converted to voltage, buffered, and sent off-chip as an analog signal. All of the pixel can be devoted to light capture, and the output's uniformity (a key factor in image quality) is high."
"In a CMOS sensor, each pixel has its own charge-to-voltage conversion, and the sensor often also includes amplifiers, noise-correction, and digitization circuits, so that the chip outputs digital bits. These other functions increase the design complexity and reduce the area available for light capture."
