The SP-810UZ has a CCD sensor type which is better than most similar spec digital cameras that have been on the market for around the same time as it. Most MILC digital 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 camera's sensor type (CCD) is actually the best sensor type amongst all MILC digital cameras that have been available for more than two years.
The worst sensor type across similar types of camera is MOS.
There are a number of other digital cameras that have a CCD sensor currently available which you might also want to look at including the Leica M Monochrom[plb_1983444_price] which has better reviews.
