The Canon PowerShot SX400 IS has a CCD sensor type which is better than most bridge cameras that were launched around the same time as it. Most digital cameras that are a comparable age to 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 actually the best sensor type across all recently released bridge cameras.
The worst sensor type across similar types of digital camera is MOS.
It may also be worth also looking at one of the alternative cameras that have a CCD sensor currently available including the Medion Life X44022[plb_2800991_price] which has better reviews.
