The DSC-H300 has a CCD sensor type which is better than the MOS sensor type found on most bridge camera digital cameras that have been on the market for a comparable time to it. 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 in fact the best sensor type across all bridge camera digital cameras that have been around for around the same time as the DSC-H300.
A MOS sensor type is the worst sensor type amongst similar types of camera.
We think you might also be interested in some of the alternative cameras that have a CCD sensor currently available including the Fujifilm FinePix SL240[plb_1349973_price] which has better reviews; or the Fujifilm S4500[plb_1353342_price] which is cheaper.
