The S (Type 006) has a better sensor type than most digital cameras that have been around for around the same time as it. This digital camera has a CCD sensor type, whereas most SLR cameras that were released more than two years ago have a MOS sensor type. CCD sensors produce high quality, low-noise images but consume a lot more power than CMOS sensors. CCD is the most common image sensor type used in digital cameras.
This digital camera's sensor type (CCD) is actually the best sensor type across all comparable spec cameras that were launched around the same time as the S (Type 006).
The worst sensor type across similar types of digital camera is MOS.
