The P300's BSI (back side illuminated) CMOS sensor does pretty well in most shooting conditions and in normal use, image quality compares well to those of its peers with similar-sized sensors.

Nikon uses the acronym "BSI" sensor. You gotta love Nikon's acronyms, almost as good as CBS TV's "See BS" acronym for Columbia Broadcasting System. Even without the BS acronym, "backside illuminator" is a hoot.

BSI refers to the British Standards Institute which determined the B.S. system. It employed the same film speed numbering system as the American Standards Association- ASA.
