The FinePix SL 300 has a CCD sensor type which is better than the MOS sensor type found on most comparable spec digital cameras that were launched around the same time as 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.
A CCD sensor type is actually the best sensor type amongst all cameras that have been around for a similar time to the FinePix SL 300.
The worst sensor type amongst comparable types of digital camera is MOS.
It may also be worth also looking at one of the other digital cameras that have a CCD sensor currently available including the Fujifilm FinePix SL240[plb_1349973_price] which has better reviews; or the Sony DSC-H300[plb_1611594_price] which is cheaper.
