Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Bought this Nikon Z50 to replace my D5500. Great camera, small compact and amazing photos. The 2 lens kits are all you need. I suggest you also buy a screen protector ($8 on EBay) and lens filters to protect the lenses.
