The Panasonic Lumix DMC-LZ40 has a CCD sensor type which is better than most cameras of a comparable age and type to it. Most cameras of this age and type 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.
A CCD sensor type is actually the best sensor type across all bridge cameras that were launched more than two years ago.
Across similar types of camera the worst sensor type is MOS.
