There are two primary styles of sensor in digital cameras today. There is the more traditional CCD which is common and the newer CMOS style of sensor. Both have their advantages and disadvantages as outlined below.
The sensor is important to consider as this is how the camera actually captures and stores all of your images. The CCD sensor is in most cameras. It stands for couple charged device – which doesn’t really explain its function at all.
Having the backing of history means it is in a good place as far as reliability and stability go. It’s been tested and improved over the years to what you will find today. The major advantages are that it offers the better quality point and has been improved on to the point that it is now equipped with technology to make it very fast and with a fantastic range.
If you’re looking at a Canon Rebel camera then you’ll be looking at the CMOS sensor. This is a newer type favored by Canon and stands for complementary metal-oxide semiconductor. Originally this chip wasn’t that great to use because it was very noisy however this has been improved greatly since its original release.
It has been improved to the level of beating out some CCDs in quality. One of the key advantages is that it uses less power which equals longer battery life. The disadvantages for both sensors vary and are pretty much opposite each other.
What one does well the other lacks. For example, CCD sensors are generally smaller than CMOS which means you can have a more compact camera body for simpler handling. However, the CMOS sensor is going to lead to larger cameras because of its increased size.
When it comes to choosing which sensor to go with you need to consider whether size is a factor. If so then the CCD may be more appropriate, however if you don’t mind the bulk then the better battery life and sensitivity of a CMOS may suit your needs.
