Default CDD Resolution

Can anyone let me know wich one is better, a camera with 1/1.8" CCD or a 1/2.7" CDD?

Thanks

Generally speaking bigger CCD means less noise. So in this case 1/1.8" would be better. In real life the size is only just one matter. Of course there are also many other things to note when comparing CCDs.

Thank You.

I want to buy a Sony DSC-P72, or a Sony DSC-P8, but I just found a unique difference the P72 has 1/1.8" DCC and the P8 has a 1/2.7" CCD, and I don't know wich one is better.

You should also look at how many megapixels those CCDs have. But CCD size and MP are less important issues than how does the camera feel in your hands, ease of operation, and if it takes good pictures!

Here are two complications when saying that a larger CCD is better.

First, make sure you are comparing similar resolutions. What is really important is the size of the photo sensors on the CCD. The more resolution, the smaller the sensors, the less the light, the more the signal needs to be amplified, the more noise is amplified. Basicaly a 6mp 1/1.8" CCD is not going to be as noise free as a 2mp 1/2.7" CCD.

Again, how big are those sensors? Do they use more square micons for each sensor when they increase the CCD size, or do they just space them farther apart?

I don't know where you will find the dimensions for the sensors, or if they combine sensors, but this does seem like important information.
