The DSC-W810 has a better sensor type than most comparable spec digital cameras that were launched in the last 12 months. This camera has a CCD sensor type, whereas most comparable spec digital cameras that have been around for around the same time as it 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 in fact the best sensor type amongst all Compact cameras that were released in the last year.
Amongst comparable types of digital camera the worst sensor type is MOS.
Alternative cameras that have a CCD sensor currently available that you might want to look at include the IXUS 177 (£94.92), or the IXUS 175 (£77.00) both from Canon or the Kodak Pixpro FZ43 (£54.99) which has better reviews.
