| What are the differences, pros and cons of each, which is better? Can someone explain? |

| Besides the CCDs being cheaper(?) I think we should wait for a couple of our engineer-types to answer .... |

There are lots of articles on this topic on the internet. Kodak's analysis for digital cameras is here. For the most part, it probably just doesn't matter (although I didn't read the article and I'm no expert on the subject). There are excellent cameras that use each type of chip.
To some extent, the physical size of the chip (either type) is a more important factor than the type. Larger chips generally result in less noise. Edit- CCD sensors are supposed to yield higher quality images, but the overwhelming popularity of the CMOS-based Canon EOS 10D and Digital Rebel on this site would appear to contradict that assumption.

| Canon has an article with some good insight available here and another page here. They point out that CMOS uses about 1/5th the power of a CCD (which is one reason Canon DSLR's can take so many shots per battery charge), how much faster CMOS is than a CCD (CCD's operate sequentially), and the cost benefit of CMOS. Although "noise" is commonly listed as a problem with CMOS, Canon has basically solved that issue, as any pic from a 10D, D60 or 300D will show. They discuss that in this article. |

Erm... I'm not sure that is correct.
CCD devices do use MOS capacitors, but do not implement CMOS technology (the combination of NMOSFET and PMOSFET transistors).

CCDs are PITA to make, compared to CMOS. They are also a pain to power, integrate and generally use. This is one of the main reasons behind the increasing popularity of CMOS sensors.
As CMOS is about the main semiconductor technology right now, you can integrate everything else, right on the same substrate as the sensor. a CCD requires a different fab process and ends up being more expensive, more power hungry, more prone to noise, more costly to integrate, more expensive to package and a lot slower.

Hmmm... I'm wondering about the Canon 10D using the CMOS sensor and the Nikon D70 using a CCD sensor. I saw an article that said CCD's gave better quality at cost of speed but I always like to ask the "pros"... so what one of those sensors is the best do you think? The Nikon uses the Sony sensor I think...
Not trying to start a flame war here, just looking for unbiased facts if they exist. |

Like questions about 'which is the best camera' I have the same answer.
It's the one that gives _you_ the best pictures.

CMOS is a process, CCD a type of device of which CMOS can be a subset. |

Note that the red ribbon winner for Portrait was shot with a D70. There are plenty of Canon examples around. You be the judge. |

| I know that they are both great cameras, I have the 300D already, but was just wondering if they both had strong points, or if they basically are the same thing with different brands. |
