Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
I have read some disappointing reviews from buyers , the camera is meant for daylight photography. Keep the ISO low at 100 for daylight, for long zoom shot put the cam on tripod or firm place . I think this camera is capable of great picture quality with nice sharpness and color.
